+ * This activity provides a comprehensive user interface for managing player information including: + *

    + *
  • Creating new player profiles with username and profile picture
    • + *
  • Editing existing player profiles
    • + *
  • Advanced image cropping functionality with pan and pinch-to-zoom controls
    • + *
  • Saving profile pictures to internal storage
    • + *
+ *

+ *

+ * The activity features two distinct UI modes: + *

    + *
  • Form Mode: Standard profile editing with username input and profile picture selection
    • + *
  • Crop Mode: Interactive image cropping interface with gesture controls for precise framing
    • + *
+ *

+ *

+ * Image Processing Pipeline: + *

    + *
  1. User selects an image from their gallery
    2. + *
  2. Activity switches to Crop Mode with the selected image
    3. + *
  3. User can pan (drag) and pinch-to-zoom to frame the desired area
    4. + *
  4. A square crop overlay shows the final cutout area
    5. + *
  5. Upon confirmation, the cropped image is saved to internal storage
    6. + *
  6. Activity returns to Form Mode with the cropped image displayed
    7. + *
+ *

+ *

+ * Usage: + * To edit an existing player, pass the player ID via intent extra using {@link #EXTRA_PLAYER_ID}. + * If no extra is provided, the activity operates in "create new player" mode. + *

+ * + * @see AppCompatActivity + * @see Player + * @see CropOverlayView + * @see AppDatabase + * @author Oche Companion Development Team + * @version 1.0 + * @since 1.0 + */ +public class AddPlayerActivity extends AppCompatActivity { + + /** + * Tag for logging and debugging purposes. + * Used to identify log messages originating from this activity. + */ + private static final String TAG = "Oche_AddPlayer"; + + /** + * Intent extra key for passing an existing player's ID for editing. + *

  1. Original Image Dimensions: The actual pixel dimensions of the source bitmap

  4. User Scale (Zoom): The scale factor from user pinch-to-zoom gestures

+ *

+ *

+ * Algorithm Overview: + *

    + *
  1. Decode the full bitmap from the URI
    2. + *
  2. Calculate the fit-center scale applied by the ImageView
    3. + *
  3. Combine fit-center scale with user's manual zoom scale
    4. + *
  4. Determine the current position of the bitmap in screen space
    5. + *
  5. Get the crop box coordinates from the overlay
    6. + *
  6. Transform screen coordinates to bitmap pixel coordinates
    7. + *
  7. Apply bounds checking to ensure valid crop dimensions
    8. + *
  8. Extract the cropped region and save to internal storage

  9. Update the profile picture preview with the cropped image

+ * This activity provides a high-performance, professional-grade scoring interface optimized for + * rapid dart entry during live gameplay. It features a specialized numeric keyboard with dynamic + * visual feedback, real-time checkout route suggestions, and strict enforcement of standard darts + * rules including Double Out finish requirements and bust conditions. + *

+ *

+ * Game Features: + *

    + *
  • Dynamic Keyboard: Bottom-anchored number pad (1-20 + Bull) with visual + * highlighting based on selected multiplier (Single, Double, Triple)
    • + *
  • Smart Checkout Engine: Real-time route suggestions for finishes up to 170
    • + *
  • Double Out Enforcement: Game can only be won by hitting a double or bullseye
    • + *
  • Bust Detection: Automatically detects and handles bust conditions (score < 0, + * score = 1, or finishing on non-double)
    • + *
  • Live Statistics: Displays current player's leg average in real-time
    • + *
  • Turn Tracking: Visual indicators show all three darts of the current turn
    • + *
+ *

+ *

+ * X01 Game Rules Enforced: + *

    + *
  • Players start at a predefined score (501, 301, etc.)
    • + *
  • Scores are subtracted with each dart throw
    • + *
  • Game must finish exactly on zero (no negative scores)
    • + *
  • Final dart must be a double (Double Out rule)
    • + *
  • Leaving a score of 1 is a bust (impossible to finish)
    • + *
  • Scoring below 0 is a bust (turn ends, score reverts)

+ *

+ * Game Flow: + *

    + *
  1. Activity is started with player list and starting score (e.g., 501)
    2. + *
  2. First player begins their turn
    3. + *
  3. Player selects multiplier (1×, 2×, or 3×)
    4. + *
  4. Player taps number on keyboard to register dart
    5. + *
  5. Score updates immediately, checkout routes appear when applicable
    6. + *
  6. After 3 darts or winning/busting, turn ends (auto or via Submit)
    7. + *
  7. Next player's turn begins automatically
    8. + *
  8. Game continues until a player finishes exactly on 0 with a double
    9. + *
+ *

+ *

+ * Usage Example: + * 

+ * // Start a 501 game with two players
+ * ArrayList<Player> players = new ArrayList<>();
+ * players.add(player1);
+ * players.add(player2);
+ * GameActivity.start(context, players, 501);
+ * 
+ * // Or start a 301 game
+ * GameActivity.start(context, players, 301);
+ *
+ *

+ *

+ * Bust Conditions: + * A turn results in a bust (score reverts, turn ends) when: + *

    + *
  • Negative Score: Dart causes score to go below 0
    • + *
  • Score of 1: Impossible to finish (no double equals 1)
    • + *
  • Zero on Non-Double: Finishing dart must be a double
    • + *
+ * Example: Player on 32 hits single 16, leaving 16. Then hits single 16 = BUST (not a double). + *

+ *

+ * Multiplier System: + *

    + *
  • Single (1×): Normal value (e.g., 20 = 20 points)
    • + *
  • Double (2×): Double value (e.g., 20 = 40 points), red highlight
    • + *
  • Triple (3×): Triple value (e.g., 20 = 60 points), blue highlight
    • + *
  • Bull (25): Single bull = 25, Double bull = 50
    • + *
+ * Note: Multiplier resets to 1× after each dart for safety. + *

+ *

+ * Checkout Engine: + * Provides optimal finishing routes when player is within checkout range (≤170): + *

    + *
  • Direct doubles for scores ≤40
    • + *
  • Setup dart suggestions to leave common doubles
    • + *
  • Pre-calculated routes for classic checkouts (170, 141, etc.)
    • + *
  • Intelligent logic to avoid leaving score of 1
    • + *
+ *

+ *

+ * Performance Optimizations: + *

    + *
  • Keyboard buttons cached in list for rapid style updates
    • + *
  • Score calculations done immediately (no database queries during play)
    • + *
  • UI updates triggered only on state changes
    • + *
  • Minimal layout inflation (keyboard built once)
    • + *
+ *

+ *

+ * Future Enhancements: + * Consider adding: + *

    + *
  • Match statistics (180s, checkout percentage, etc.)
    • + *
  • Undo turn (not just undo dart)
    • + *
  • Pause/resume functionality
    • + *
  • Sound effects for checkouts and busts
    • + *
  • Throw history visualization
    • + *
  • Practice mode with AI opponent

+ *

+ * Three-Dart Average Calculation: + * 

+     * Average = ((startingScore - remainingScore) / dartsThrown) × 3

+     * Example:
+     * Starting score: 501
+     * Remaining score: 201
+     * Darts thrown: 30
+     * Points scored: 501 - 201 = 300
+     * Average: (300 / 30) × 3 = 30.0
+     *
+ * Displayed as "AVG: 30.0" in the UI. + *

+ *

+ * Current Target Calculation: + * The target score considers darts thrown but not yet submitted: + * 

+     * currentTarget = remainingScore - sumOfCurrentTurnDarts

  1. Direct Doubles: For scores ≤40 and even, suggest immediate double

  2. Bullseye: For score of 50, suggest BULL (double bull)

  5. Fallback: Generic high-score route (T20 Route)
    6. + *
+ *

+ *

+ * Key Rule: Never suggests a route that would leave a score of 1, as + * this is impossible to finish (no double equals 1). + *

+     * getRoute(40, 2) → "D20"           (Direct double)
+     * getRoute(41, 2) → "1 • D20"       (Setup dart to leave 40)

  • Generic advice: "T20 Route" (for high scores)
    • + *
+ * The bullet character (•) separates individual darts in multi-dart routes. + *

+ *

+ * Algorithm Steps: + *

    + *
  1. Check for direct double finish (score ≤40, even) → "D[N]"
    2. + *
  2. Check for bullseye finish (score = 50) → "BULL"
    3. + *
  3. If multiple darts available and odd score: + *
      + *
    • Try to leave common double (32→D16, 40→D20, 16→D8)
      • + *
    • Default: suggest 1 to leave even score for double

  5. Fallback to generic "T20 Route" for high scores (>60)
    6. + *
  6. Return null if no route available
    7. + *
+ *

+ *

+ * Setup Dart Logic: + * When score is odd with 2+ darts left, suggests setup darts to leave doubles: + * 

+         * Score 41: Suggest "1 • D20" (leaves 40)
+         * Score 39: Suggest "7 • D16" (leaves 32)
+         * Score 47: Suggest "7 • D20" (leaves 40)
+         *
+ * Prioritizes leaving 32 (D16) or 40 (D20) as these are common target doubles. + *

+ *

+ * Example Calls: + * 

+         * CheckoutEngine.getRoute(32, 1);   // Returns "D16"
+         * CheckoutEngine.getRoute(50, 1);   // Returns "BULL"

+ * This abstract class serves as the central database access point, managing all + * data persistence for players, matches, and related statistics. It implements + * the Singleton design pattern to ensure only one database instance exists + * throughout the application lifecycle, preventing resource conflicts and ensuring + * data consistency. + *

+ *

+ * Room Database Architecture: + * Room is Android's SQLite object-relational mapping (ORM) library that provides + * an abstraction layer over SQLite, offering: + *

    + *
  • Compile-time SQL query verification
    • + *
  • Convenient annotation-based entity and DAO definitions
    • + *
  • Automatic conversion between SQLite and Java/Kotlin objects
    • + *
  • LiveData and Flow support for reactive UI updates
    • + *
  • Migration support for database schema changes
    • + *
+ *

+ *

+ * Database Entities: + * This database manages two primary tables: + *

    + *
  • players: Squad roster with player profiles and career statistics + * (defined by {@link Player} entity)
    • + *
  • matches: Completed match records with participant data and results + * (defined by {@link Match} entity)
    • + *
+ *

+ *

+ * Database Access Objects (DAOs): + * Database operations are performed through specialized DAO interfaces: + *

    + *
  • {@link PlayerDao}: CRUD operations for player management (insert, update, query)
    • + *
  • {@link MatchDao}: Match record operations (insert, query all, query last match)
    • + *
+ *

+ *

+ * Singleton Pattern Implementation: + * The class uses the thread-safe double-checked locking pattern to ensure a single + * database instance. This approach: + *

    + *
  • Prevents multiple database connections that waste resources
    • + *
  • Ensures data consistency across the application
    • + *
  • Reduces memory overhead by sharing one connection pool
    • + *
  • Thread-safe initialization prevents race conditions
    • + *
+ *

+ *

+ * Usage Example: + * 

+ * // Get database instance (can be called from any activity/fragment)
+ * AppDatabase db = AppDatabase.getDatabase(context);
+ * 
+ * // Access DAOs for database operations
+ * PlayerDao playerDao = db.playerDao();
+ * MatchDao matchDao = db.matchDao();
+ * 
+ * // Perform database operations (must be on background thread)
+ * new Thread(() -> {
+ *     // Insert a new player
+ *     Player player = new Player("John Doe", "/path/to/pic.jpg");
+ *     playerDao.insert(player);
+ *     
+ *     // Query all players
+ *     List<Player> allPlayers = playerDao.getAllPlayers();
+ *     
+ *     // Insert a match
+ *     Match match = new Match(System.currentTimeMillis(), "501", 2, participantJson);
+ *     matchDao.insert(match);
+ *     
+ *     // Get recent matches
+ *     List<Match> recentMatches = matchDao.getAllMatches();
+ * }).start();
+ *
+ *

+ *

+ * Database Versioning: + * Currently at version 2, indicating one schema change since initial creation. + * Version increments are required when: + *

    + *
  • Adding or removing tables
    • + *
  • Adding or removing columns
    • + *
  • Changing column types or constraints
    • + *
  • Modifying primary keys or indices
    • + *
+ * The {@code fallbackToDestructiveMigration()} strategy means schema changes will + * drop and recreate all tables, losing existing data. This is acceptable during + * development but should be replaced with proper migrations for production. + *

+ *

+ * Migration Strategy: + * For production releases, replace destructive migration with proper migration paths: + * 

+ * static final Migration MIGRATION_1_2 = new Migration(1, 2) {
+ *     @Override
+ *     public void migrate(@NonNull SupportSQLiteDatabase database) {
+ *         // Example: Add new column to players table
+ *         database.execSQL("ALTER TABLE players ADD COLUMN wins INTEGER NOT NULL DEFAULT 0");
+ *     }
+ * };
+ * 
+ * INSTANCE = Room.databaseBuilder(context.getApplicationContext(),
+ *                 AppDatabase.class, "oche_companion_db")
+ *         .addMigrations(MIGRATION_1_2)  // Add migration instead of destructive
+ *         .build();
+ *
+ *

+ *

+ * Database File Location: + * The SQLite database file "oche_companion_db" is stored in the app's private + * storage at: + * 

+ * /data/data/com.aldo.apps.ochecompanion/databases/oche_companion_db
+ *
+ * This location is: + *
    + *
  • Private to the application (other apps cannot access)
    • + *
  • Automatically backed up with Auto Backup (if enabled)
    • + *
  • Cleared when the app is uninstalled
    • + *
  • Accessible for inspection via Android Studio Database Inspector
    • + *
+ *

+ *

+ * Schema Export: + * The {@code exportSchema = false} setting disables automatic schema JSON export. + * For production apps, consider enabling this: + * 

+ * @Database(entities = {...}, version = 2, exportSchema = true)
+ *
+ * And specify the export directory in build.gradle: + * 
+ * android {
+ *     defaultConfig {
+ *         javaCompileOptions {
+ *             annotationProcessorOptions {
+ *                 arguments += ["room.schemaLocation": "$projectDir/schemas"]
+ *             }
+ *         }
+ *     }
+ * }
+ *
+ * This creates version-controlled schema files for tracking changes and testing migrations. + *

+ *

+ * Threading Requirements: + * Room enforces that database operations occur on background threads: + *

    + *
  • Attempting database operations on the main thread throws {@link IllegalStateException}
    • + *
  • Use {@link Thread}, {@link java.util.concurrent.ExecutorService}, or Kotlin coroutines
    • + *
  • UI updates after database operations must use {@code runOnUiThread()} or similar
    • + *
  • Consider using LiveData or Flow for automatic thread handling and UI updates
    • + *
+ *

+ *

+ * Database Inspection: + * For debugging, you can inspect the database using: + *

    + *
  • Android Studio Database Inspector: View > Tool Windows > Database Inspector
    • + *
  • ADB: {@code adb shell} and SQLite command line
    • + *
  • Third-party tools: DB Browser for SQLite (requires root or backup)
    • + *
+ *

+ *

+ * Performance Optimization: + *

    + *
  • Database queries are optimized with SQLite indices on primary keys
    • + *
  • Connection pooling is handled automatically by Room
    • + *
  • Consider adding custom indices for frequently queried columns: + * 
    @Entity(indices = {@Index(value = {"username"})})
    • + *
  • Use transactions for batch operations to improve performance
    • + *
  • Avoid N+1 query problems by using JOIN queries or @Relation
    • + *
+ *

+ *

+ * Testing: + * For unit testing, create an in-memory database: + * 

+ * @Before
+ * public void createDb() {
+ *     Context context = ApplicationProvider.getApplicationContext();
+ *     db = Room.inMemoryDatabaseBuilder(context, AppDatabase.class)
+ *             .allowMainThreadQueries()  // OK for tests
+ *             .build();
+ *     playerDao = db.playerDao();
+ * }
+ * 
+ * @After
+ * public void closeDb() {
+ *     db.close();
+ * }
+ *
+ *

+ *

+ * Data Backup and Restore: + * Consider implementing backup functionality: + *

    + *
  • Export database to external storage or cloud
    • + *
  • Use Android's Auto Backup for automatic cloud backup
    • + *
  • Provide manual export/import for user control
    • + *
  • Validate data integrity after restore operations
    • + *
+ *

+ *

+ * Security Considerations: + *

    + *
  • Database is stored in app's private directory (secure by default)
    • + *
  • For sensitive data, consider using SQLCipher for encryption
    • + *
  • Be cautious when exporting database (may contain user data)
    • + *
  • Validate and sanitize all data before insertion to prevent SQL injection + * (Room's parameterized queries provide protection)
    • + *
+ *

+ *

+ * Future Enhancements: + * Consider these improvements for future versions: + *

    + *
  • Add proper migration strategies instead of destructive migration
    • + *
  • Implement database encryption with SQLCipher
    • + *
  • Add support for exporting/importing data
    • + *
  • Create additional entities for tournaments, achievements, settings
    • + *
  • Implement multi-user support with user profiles table
    • + *
  • Add full-text search capabilities with FTS tables
    • + *

+ * This abstract method is implemented by Room at compile time, returning an + * instance of the {@link PlayerDao} interface. The DAO (Data Access Object) + * provides methods for all player-related database operations including + * creating, reading, updating, and managing player records. + *

+ *

+ * Available Operations: + * The returned PlayerDao provides these methods: + *

    + *
  • {@link PlayerDao#insert(Player)} - Add new player to squad
    • + *
  • {@link PlayerDao#update(Player)} - Update existing player information
    • + *
  • {@link PlayerDao#getPlayerById(int)} - Retrieve specific player by ID
    • + *
  • {@link PlayerDao#getAllPlayers()} - Get all players sorted alphabetically
    • + *
+ *

+ *

+ * Usage Example: + * 

+     * // Get database instance
+     * AppDatabase db = AppDatabase.getDatabase(context);
+     * 
+     * // Get PlayerDao
+     * PlayerDao playerDao = db.playerDao();
+     * 
+     * // Perform operations on background thread
+     * new Thread(() -> {
+     *     // Create and insert new player
+     *     Player newPlayer = new Player("Alice", "/path/to/pic.jpg");
+     *     playerDao.insert(newPlayer);
+     *     
+     *     // Query all players
+     *     List<Player> squad = playerDao.getAllPlayers();
+     *     
+     *     // Update player stats
+     *     Player player = playerDao.getPlayerById(5);
+     *     if (player != null) {
+     *         player.careerAverage = 85.5;
+     *         player.matchesPlayed++;
+     *         playerDao.update(player);
+     *     }
+     *     
+     *     // Update UI on main thread
+     *     runOnUiThread(() -> updateSquadDisplay(squad));
+     * }).start();
+     *
+ *

+ *

+ * Thread Safety: + * While the DAO instance itself is thread-safe and can be reused across multiple + * threads, all database operations must be performed on background threads to + * comply with Room's threading policy. Attempting to execute queries on the + * main thread will result in an {@link IllegalStateException}. + *

+ *

+ * DAO Lifecycle: + * The DAO instance is created once by Room and can be cached and reused: + * 

+     * // Good: Reuse DAO instance
+     * PlayerDao playerDao = db.playerDao();
+     * // Use playerDao for multiple operations
+     * 
+     * // Also fine: Get DAO each time (Room caches internally)
+     * db.playerDao().insert(player1);
+     * db.playerDao().insert(player2);
+     *
+ *

+ *

+ * Common Usage Patterns: + * 

+     * // Pattern 1: Simple query and UI update
+     * ExecutorService executor = Executors.newSingleThreadExecutor();
+     * executor.execute(() -> {
+     *     List<Player> players = db.playerDao().getAllPlayers();
+     *     runOnUiThread(() -> adapter.setPlayers(players));
+     * });
+     * 
+     * // Pattern 2: Insert and navigate
+     * new Thread(() -> {
+     *     Player player = new Player("John", picUri);
+     *     db.playerDao().insert(player);
+     *     runOnUiThread(() -> {
+     *         Toast.makeText(context, "Player added", Toast.LENGTH_SHORT).show();
+     *         finish();
+     *     });
+     * }).start();
+     * 
+     * // Pattern 3: Edit flow (query, modify, update)
+     * new Thread(() -> {
+     *     Player player = db.playerDao().getPlayerById(playerId);
+     *     if (player != null) {
+     *         player.username = newName;
+     *         player.profilePictureUri = newPicUri;
+     *         db.playerDao().update(player);
+     *         runOnUiThread(() -> Toast.makeText(context, "Updated", Toast.LENGTH_SHORT).show());
+     *     }
+     * }).start();
+     *
+ *

+ *

+ * Alternative Reactive Approaches: + * Consider using LiveData or Flow for automatic UI updates: + * 

+     * // If PlayerDao had LiveData support:

+ * Available Operations: + * The returned MatchDao provides these methods: + *

    + *
  • {@link MatchDao#insert(Match)} - Save completed match to history

+ * Thread Safety: + * Like PlayerDao, the MatchDao instance is thread-safe and can be reused across + * threads. However, all database operations must execute on background threads. + * Room will throw an {@link IllegalStateException} if database operations are + * attempted on the main thread. + *

+ *

+ * Performance Considerations: + *

    + *
  • getAllMatches() loads all match records - consider pagination for users + * with hundreds of matches
    • + *
  • getLastMatch() uses LIMIT 1 for efficient querying
    • + *
  • Matches are ordered by timestamp DESC for chronological display
    • + *
  • Consider adding date range queries for filtering match history
    • + *
+ *

+ *

+ * Statistical Queries: + * 

+     * // Get match history for analysis
+     * new Thread(() -> {
+     *     List<Match> allMatches = db.matchDao().getAllMatches();
+     *     
+     *     // Calculate statistics
+     *     int totalMatches = allMatches.size();
+     *     Map<String, Integer> gameModeCount = new HashMap<>();
+     *     
+     *     for (Match match : allMatches) {
+     *         gameModeCount.merge(match.gameMode, 1, Integer::sum);
+     *     }
+     *     
+     *     // Display stats
+     *     runOnUiThread(() -> showStatistics(totalMatches, gameModeCount));
+     * }).start();
+     *
+ *

+ *

+ * DAO Lifecycle: + * The DAO instance can be cached and reused throughout the app: + * 

+     * // Cache in Application class or repository
+     * private MatchDao matchDao;
+     * 
+     * public MatchDao getMatchDao() {

+ * This static field holds the single database instance for the entire application. + * Using the volatile keyword ensures proper visibility across threads in the + * double-checked locking pattern, preventing potential issues where one thread's + * changes might not be visible to other threads. + *

+ *

+ * Volatile Keyword: + * The volatile modifier guarantees: + *

    + *
  • Happens-before relationship: Writes to INSTANCE are visible to all threads
    • + *
  • Prevents instruction reordering that could break double-checked locking
    • + *
  • Ensures thread sees the fully constructed object, not a partially initialized one
    • + *
  • No caching of the variable value in CPU registers
    • + *
+ *

+ *

+ * Initialization State: + *

    + *
  • null: Before first call to {@link #getDatabase(Context)}
    • + *
  • non-null: After database is created, remains set for app lifetime
    • + *
+ *

+ *

+ * Memory Lifecycle: + * The database instance is retained in memory for the lifetime of the application + * process. It will be garbage collected only when: + *

    + *
  • The app process is terminated by Android
    • + *
  • The app is killed by the user
    • + *
  • System needs to reclaim memory and kills the app's process
    • + *
+ *

+ *

+ * Testing Considerations: + * For unit tests, you may need to reset the singleton: + * 

+     * // In test teardown (requires reflection or test-only setter)
+     * @After
+     * public void tearDown() {
+     *     // Close database
+     *     if (AppDatabase.INSTANCE != null) {
+     *         AppDatabase.INSTANCE.close();
+     *         // Reset singleton (would need package-private setter)
+     *         AppDatabase.INSTANCE = null;
+     *     }
+     * }
+     *
+ *

+ *

+ * Why Singleton: + * Using a singleton for the database instance provides: + *

    + *
  • Single connection pool shared across the app
    • + *
  • Consistent data state across all components
    • + *
  • Reduced memory overhead (no duplicate instances)
    • + *
  • Prevention of conflicting database access
    • + *
  • Simplified database access (no need to pass instance around)
    • + *
+ *

+ *

+ * Thread Safety Analysis: + * The volatile keyword combined with synchronized block in {@link #getDatabase(Context)} + * ensures thread-safe lazy initialization: + * 

+     * // Thread 1 checks: INSTANCE == null (true)
+     * // Thread 1 enters synchronized block
+     * // Thread 1 creates database instance
+     * // Thread 1 assigns to INSTANCE (volatile write)
+     * 
+     * // Thread 2 checks: INSTANCE == null (false, sees Thread 1's write)
+     * // Thread 2 returns existing instance without entering synchronized block
+     *
+ *

+ * + * @see #getDatabase(Context) + * @see RoomDatabase + */ + private static volatile AppDatabase INSTANCE; + + /** + * Gets the singleton instance of the AppDatabase, creating it if necessary. + *

+ * This method implements the thread-safe double-checked locking pattern to ensure + * only one database instance is created, even when called simultaneously from + * multiple threads. The method is safe to call from any thread and can be invoked + * from any component (Activity, Fragment, Service, etc.). + *

+ *

+ * Double-Checked Locking Pattern: + * The implementation uses two null checks to optimize performance: + *

    + *
  1. First check (unsynchronized): Fast path for when instance exists. + * Avoids expensive synchronization on subsequent calls.
    2. + *
  2. Synchronized block: Ensures only one thread creates the instance. + * Prevents race conditions during initialization.
    3. + *
  3. Second check (synchronized): Prevents multiple creation if several + * threads passed the first check simultaneously.
    4. + *
+ *

+ *

+ * Usage Example: + * 

+     * // From Activity
+     * public class MainActivity extends AppCompatActivity {
+     *     @Override
+     *     protected void onCreate(Bundle savedInstanceState) {
+     *         super.onCreate(savedInstanceState);
+     *         
+     *         // Get database instance
+     *         AppDatabase db = AppDatabase.getDatabase(this);
+     *         
+     *         // Use DAOs for database operations
+     *         new Thread(() -> {
+     *             List<Player> players = db.playerDao().getAllPlayers();
+     *             runOnUiThread(() -> displayPlayers(players));
+     *         }).start();
+     *     }
+     * }
+     * 
+     * // From Fragment
+     * AppDatabase db = AppDatabase.getDatabase(requireContext());
+     * 
+     * // From Service
+     * AppDatabase db = AppDatabase.getDatabase(getApplicationContext());
+     * 
+     * // From anywhere with Context
+     * AppDatabase db = AppDatabase.getDatabase(context);
+     *
+ *

+ *

+ * Context Parameter: + * The method accepts any Context but internally uses {@code context.getApplicationContext()} + * to avoid memory leaks. This means: + *

    + *
  • Activity context is safe to pass (converted to app context)
    • + *
  • Fragment context is safe to pass (converted to app context)
    • + *
  • Application context is ideal but not required
    • + *
  • No risk of leaking Activity or Fragment references
    • + *
+ *

+ *

+ * Database Builder Configuration: + * The database is created with these settings: + * 

+     * Room.databaseBuilder(
+     *     context.getApplicationContext(),          // App context to prevent leaks
+     *     AppDatabase.class,                        // Database class
+     *     "oche_companion_db"                       // Database file name
+     * )
+     * .fallbackToDestructiveMigration()            // Drop tables on version change
+     * .build();
+     *
+ *

+ *

+ * Destructive Migration Strategy: + * The {@code fallbackToDestructiveMigration()} setting means: + *

    + *
  • Advantage: No need to write migration code during development
    • + *
  • Disadvantage: All data is lost when database version changes
    • + *
  • Development: Acceptable for testing and iteration
    • + *
  • Production: Should be replaced with proper migrations: + * 
    .addMigrations(MIGRATION_1_2, MIGRATION_2_3)
    + *
    • + *
+ *

+ *

+ * First Call Initialization: + * On the first call, this method will: + *

    + *
  1. Create the SQLite database file in app's private storage
    2. + *
  2. Create all tables defined by entity classes (players, matches)
    3. + *
  3. Set up indices and constraints
    4. + *
  4. Initialize Room's internal structures
    5. + *
  5. Return the ready-to-use database instance
    6. + *
+ * This initialization is typically fast (< 100ms) but happens on the calling thread, + * so consider calling from a background thread if concerned about main thread performance. + *

+ *

+ * Subsequent Calls: + * After initialization, subsequent calls: + *

    + *
  • Return immediately (fast path, no synchronization)
    • + *
  • No database access or initialization overhead
    • + *
  • Thread-safe from all threads
    • + *
  • Essentially free performance-wise
    • + *
+ *

+ *

+ * Thread Safety Guarantee: + * 

+     * // Safe to call from multiple threads simultaneously
+     * Thread thread1 = new Thread(() -> {
+     *     AppDatabase db = AppDatabase.getDatabase(context);
+     *     db.playerDao().insert(player1);
+     * });
+     * 
+     * Thread thread2 = new Thread(() -> {
+     *     AppDatabase db = AppDatabase.getDatabase(context);
+     *     db.playerDao().insert(player2);
+     * });
+     * 
+     * thread1.start();
+     * thread2.start();
+     * // Both threads will use the same database instance
+     *
+ *

+ *

+ * Best Practices: + *

    + *
  • Call early in app lifecycle (Application.onCreate()) to avoid first-call delay
    • + *
  • Use application context when possible for clarity
    • + *
  • No need to cache the returned instance (method is fast)
    • + *
  • Safe to call repeatedly throughout the app
    • + *
+ *

+ *

+ * Proactive Initialization: + * 

+     * public class OcheCompanionApplication extends Application {
+     *     @Override
+     *     public void onCreate() {
+     *         super.onCreate();
+     *         
+     *         // Initialize database early to avoid delay on first access
+     *         AppDatabase.getDatabase(this);
+     *     }
+     * }
+     *
+ *

+ *

+ * Error Handling: + * In rare cases, database creation might fail due to: + *

    + *
  • Insufficient storage space
    • + *
  • Corrupted database file
    • + *
  • File system errors
    • + *
+ * Room will throw RuntimeException in these cases. Consider adding error handling: + * 
+     * try {
+     *     AppDatabase db = AppDatabase.getDatabase(context);
+     *     // Use database
+     * } catch (Exception e) {
+     *     Log.e(TAG, "Failed to open database", e);
+     *     // Show error to user, attempt recovery, etc.
+     * }
+     *
+ *

+ * This interface defines the contract for accessing and manipulating match data in the + * Room database. It provides methods for inserting new match records and querying match + * history. Room generates the implementation of this interface at compile time. + *

+ *

+ * Room Database Integration: + * The {@code @Dao} annotation indicates that this is a Room DAO interface. Room will + * automatically generate an implementation class that handles all the database operations, + * SQLite connections, cursor management, and data mapping. + *

+ *

+ * Key Features: + *

    + *
  • Insert completed match records into the database
    • + *
  • Retrieve complete match history sorted by most recent first
    • + *
  • Query the last played match for dashboard/recap displays
    • + *
  • Thread-safe operations managed by Room
    • + *
+ *

+ *

+ * Thread Safety: + * All database operations should be performed on a background thread to avoid blocking + * the main UI thread. Room enforces this for most operations on main thread and will + * throw an exception if database operations are attempted on the main thread (unless + * explicitly configured otherwise). + *

+ *

+ * Usage Example: + * 

+ * // Get DAO instance from database
+ * MatchDao matchDao = AppDatabase.getDatabase(context).matchDao();
+ * 
+ * // Insert a new match (on background thread)
+ * new Thread(() -> {
+ *     matchDao.insert(newMatch);
+ * }).start();
+ * 
+ * // Query last match (on background thread)
+ * new Thread(() -> {
+ *     Match lastMatch = matchDao.getLastMatch();
+ *     // Use lastMatch on UI thread
+ *     runOnUiThread(() -> displayMatch(lastMatch));
+ * }).start();
+ *
+ *

+ *

+ * Database Table: + * This DAO operates on the "matches" table, which is defined by the {@link Match} + * entity class with its {@code @Entity} annotation. + *

+ * + * @see Match + * @see Dao + * @see com.aldo.apps.ochecompanion.database.AppDatabase + * @author Oche Companion Development Team + * @version 1.0 + * @since 1.0 + */ +@Dao +public interface MatchDao { + + /** + * Inserts a completed match record into the database. + *

+ * This method persists a new match entry to the "matches" table. The match should + * represent a completed game with all necessary information (players, scores, timestamp, etc.). + * Room will handle the actual SQL INSERT operation and auto-increment primary keys if configured. + *

+ *

+ * Threading: + * This operation must be performed on a background thread. Attempting to call this + * on the main thread will result in an exception (unless Room is configured to allow + * main thread queries, which is not recommended). + *

+ *

+ * Transaction Behavior: + * By default, Room wraps this operation in a transaction. If the insert fails, the + * transaction will be rolled back, maintaining database consistency. + *

+ *

+ * Conflict Strategy: + * The default conflict strategy is {@code OnConflictStrategy.ABORT}, which means if + * a conflict occurs (e.g., primary key violation), the insert will fail with an exception. + * This can be customized by adding a parameter to the {@code @Insert} annotation. + *

+ *

+ * Return Value: + * While this method returns void, the {@code @Insert} annotation can be configured + * to return: + *

    + *
  • {@code long} - The row ID of the newly inserted match
    • + *
  • {@code Long} - Same as above, but nullable
    • + *
  • {@code long[]} or {@code Long[]} - For bulk inserts
    • + *
  • {@code List} - Alternative for bulk inserts
    • + *
+ *

+     * Match match = new Match(...);
+     * match.setTimestamp(System.currentTimeMillis());

  • SQLite connection management
    • + *
  • Result cursor handling and mapping to Player objects
    • + *
  • Transaction management and error handling
    • + *
+ *

+ *

+ * Key Features: + *

    + *
  • Insert: Add new players to the squad roster
    • + *
  • Update: Modify existing player information (username, profile picture, stats)
    • + *
  • Query by ID: Retrieve a specific player for editing
    • + *
  • Query All: Get the complete squad list, alphabetically sorted
    • + *
+ *

+ * Auto-Generated ID: + * After insertion, if the Player entity's ID field is auto-generated, the passed + * player object's ID field will be updated with the generated value (assuming the + * ID field is not final). + *

+ *     "highestCheckout": 120
+ *   }
+ * ]
+ *
+ * This structure allows for flexible storage of various statistics while maintaining + * database normalization (avoiding separate tables for each match-player relationship). + *

+ *

+ * Game Mode Support: + * The application supports multiple darts game variants: + *

    + *
  • 501: Standard countdown game starting at 501 points
    • + *
  • 301: Faster countdown game starting at 301 points
    • + *
  • Cricket: Number-based strategy game (15-20 and bulls)
    • + *
  • Around the Clock: Sequential number hitting game
    • + *
  • Custom game modes can be added by extending the gameMode field
    • + *
+ *

+ *

+ * Match Types: + * The system supports different match configurations: + *

    + *
  • 1v1 Matches: Two-player head-to-head games (playerCount = 2)
    • + *
  • Group Matches: Three or more players (playerCount >= 3)
    • + *
  • Solo Practice: Single player practice sessions (playerCount = 1)
    • + *
+ * The UI adapts based on player count, showing specialized layouts for each match type. + *

+ *

+ * Usage Example: + * 

+ * // Create a new match record after game completion
+ * String participantJson = buildParticipantJson(players, finalScores, rankings);
+ * Match newMatch = new Match(
+ *     System.currentTimeMillis(),  // Current time
+ *     "501",                        // Game mode
+ *     2,                            // Two players
+ *     participantJson               // Serialized player data
+ * );
+ * 
+ * // Insert into database (on background thread)
+ * new Thread(() -> {
+ *     matchDao.insert(newMatch);
+ *     // After insert, newMatch.id will contain the auto-generated ID
+ * }).start();
+ * 
+ * // Query and display matches
+ * new Thread(() -> {
+ *     List<Match> recentMatches = matchDao.getAllMatches();
+ *     runOnUiThread(() -> updateMatchRecapUI(recentMatches));
+ * }).start();
+ * 
+ * // Pass match to detail activity
+ * Intent intent = new Intent(this, MatchDetailActivity.class);
+ * intent.putExtra("match_object", matchToView); // Uses Serializable
+ * startActivity(intent);
+ *
+ *

+ *

+ * Database Relationships: + * While this entity doesn't use Room's {@code @Relation} annotations, it maintains + * logical relationships through the participant data: + *

    + *
  • Each match references multiple players via IDs in participantData JSON
    • + *
  • Player objects are stored separately in the "players" table
    • + *
  • The denormalized JSON approach optimizes read performance for match history
    • + *
  • Updates to player usernames won't automatically reflect in historical matches
    • + *
+ *

+ *

+ * Performance Considerations: + *

    + *
  • JSON parsing adds minimal overhead for typical match sizes (2-8 players)
    • + *
  • The timestamp field can be indexed for efficient chronological queries
    • + *
  • Consider paginating match history for users with hundreds of matches
    • + *
  • The Serializable interface has some overhead; consider Parcelable for better performance
    • + *
+ *

+ *

+ * Data Integrity: + *

    + *
  • The auto-generated ID ensures each match is uniquely identifiable
    • + *
  • Timestamp should always be positive and in milliseconds (Unix epoch)
    • + *
  • Player count should match the number of entries in participantData JSON
    • + *
  • Game mode string should be validated against supported game types
    • + *
+ *

+ *

+ * Future Enhancements: + * Consider adding these fields for expanded functionality: + *

    + *
  • duration: Match duration in seconds for time tracking
    • + *
  • location: Venue or location where match was played
    • + *
  • notes: User-added comments or observations
    • + *
  • isRanked: Boolean flag for competitive vs casual matches
    • + *
  • tournamentId: Reference to tournament entity for organized play

+ * This field specifies which darts game mode was used, allowing the application + * to display appropriate statistics, rules, and UI elements for that particular + * game type. The game mode determines scoring rules, win conditions, and the + * overall structure of the match. + *

+ *

+ * Supported Game Modes: + *

    + *
  • "501": The classic countdown game starting at 501 points. + * Players subtract their scores and must finish exactly on zero with a double.
    • + *
  • "301": A faster variant starting at 301 points, following + * the same rules as 501 but requiring quicker gameplay.
    • + *
  • "Cricket": Strategic game focusing on numbers 15-20 and + * the bullseye. Players must "close" numbers by hitting them three times.
    • + *
  • "Around the Clock": Sequential game where players must + * hit numbers 1-20 in order, then finish with a bullseye.
    • + *
  • "Killer": Multiplayer elimination game where each player + * has a designated number and tries to eliminate opponents.
    • + *
+ *

+ *

+ * String Format: + * Game mode strings should be: + *

    + *
  • Non-null and non-empty
    • + *
  • Consistent in naming (avoid "501", "Five-Oh-One", "501 Game" variations)
    • + *
  • Preferably using predefined constants to avoid typos
    • + *
+ *

+ *

+ * Recommended Usage: + * 

+     * // Define constants for game modes
+     * public static final String GAME_MODE_501 = "501";
+     * public static final String GAME_MODE_301 = "301";

+     * @Query("SELECT * FROM matches WHERE gameMode = '501'")
+     * List<Match> get501Matches();
+     * 
+     * // Calculate average score by game mode
+     * Map<String, Double> averagesByMode = calculateAveragesByGameMode();
+     *
+ *

+ *

+ * Extensibility: + * New game modes can be added without schema changes: + *

    + *
  • Simply use a new string identifier
    • + *
  • Implement game-specific logic in the game engine
    • + *
  • Update UI to handle the new mode
    • + *
  • Ensure participant data JSON includes mode-specific metrics

    + *
  • 1: Solo practice session (single player)
    • + *
  • 2: Head-to-head match (1v1 duel)
    • + *
  • 3+: Group match or multiplayer game

+     * }
+     *
+ *

+ *

+ * Performance Implications: + *

    + *
  • Higher player counts require more complex UI layouts
    • + *
  • Sorting and ranking algorithms scale with player count
    • + *
  • JSON parsing time increases with more participants
    • + *
  • Consider pagination for matches with many players

+ *

+ * Usage in Queries: + * 

+     * // Get all 1v1 matches
+     * @Query("SELECT * FROM matches WHERE playerCount = 2")
+     * List<Match> getDuelMatches();
+     * 
+     * // Get group matches only
+     * @Query("SELECT * FROM matches WHERE playerCount >= 3")
+     * List<Match> getGroupMatches();
+     *
+ *

+ *

+ * Statistical Analysis: + * Player count enables performance tracking by match type: + * 

+     * // Calculate win rate in 1v1 matches
+     * double winRate1v1 = calculateWinRate(playerId, 2);
+     * 
+     * // Calculate average placement in group matches
+     * double avgPlacement = calculateAveragePlacement(playerId, 3);
+     *
+ *

+ *

+ * Validation: + * Always validate player count before creating a match: + *

+ * Building Participant Data: + * 

+     * // Create JSON array when match ends
+     * JSONArray participants = new JSONArray();
+     * 
+     * for (Player player : matchPlayers) {
+     *     JSONObject playerData = new JSONObject();

+     * Match match = new Match(timestamp, gameMode, playerCount, participantDataString);
+     *
+ *

+ *

+ * Why JSON Instead of Relations: + *

    + *
  • Performance: Single query retrieves complete match data
    • + *
  • Historical Accuracy: Captures player data as it was at match time
    • + *
  • Flexibility: Can store game-specific metrics without schema changes
    • + *
  • Simplicity: Avoids complex join queries and relationship management
    • + *
  • Immutability: Match data remains unchanged if player profiles are updated
    • + *
+ *

+ *

+ * Data Integrity: + *

    + *
  • Array length should match {@link #playerCount}
    • + *
  • Ranks should be sequential (1, 2, 3, ...) without gaps
    • + *
  • Player IDs should reference valid players (though not enforced by foreign key)
    • + *
  • JSON must be well-formed and parseable
    • + *
+ *

+ *

+ * Snapshot Advantage: + * Storing username and profile picture in the match data (rather than just ID) + * preserves the historical record. If a player later changes their username from + * "John Doe" to "JD_Pro", the old match will still show "John Doe" as they were + * known at that time. + *

+ *

+ * Sorting Participants: + * Usually pre-sorted by rank before serialization, but can be sorted after parsing: + * 

+     * // Sort by rank after parsing
+     * Collections.sort(playerList, (p1, p2) -> 
+     *     Integer.compare(p1.rank, p2.rank));
+     *
+ *

+ *

+ * Null Handling: + * This field should never be null. If a match has no valid participant data, + * consider using an empty array "[]" or not creating the match at all. + *

+     *     2,                                 // Number of players
+     *     participants.toString()            // Serialized participant data

+     *     Log.d(TAG, "Match saved with ID: " + completedMatch.id);
+     * }).start();
+     *
+ *

+ *

+ * Parameter Validation: + * While the constructor doesn't enforce validation, consider checking parameters + * before construction: + * 

+     * // Validate before creating match
+     * if (timestamp <= 0) {
+     *     throw new IllegalArgumentException("Invalid timestamp");
+     * }
+     * if (gameMode == null || gameMode.isEmpty()) {
+     *     throw new IllegalArgumentException("Game mode is required");
+     * }
+     * if (playerCount < 1) {
+     *     throw new IllegalArgumentException("At least one player required");
+     * }
+     * if (participantData == null || participantData.isEmpty()) {
+     *     throw new IllegalArgumentException("Participant data is required");
+     * }
+     * 
+     * // Validate JSON format
+     * try {
+     *     JSONArray test = new JSONArray(participantData);
+     *     if (test.length() != playerCount) {
+     *         throw new IllegalArgumentException("Player count mismatch");
+     *     }
+     * } catch (JSONException e) {
+     *     throw new IllegalArgumentException("Invalid JSON format", e);
+     * }
+     * 
+     * // Create match after validation
+     * Match match = new Match(timestamp, gameMode, playerCount, participantData);
+     *
+ *

+ *

+ * Field Initialization: + * The constructor initializes all fields except {@code id}: + *

    + *
  • id: Remains 0 (default) until Room assigns auto-generated value
    • + *
  • timestamp: Set to the provided value (milliseconds since epoch)
    • + *
  • gameMode: Set to the provided game identifier string
    • + *
  • playerCount: Set to the provided player count
    • + *
  • participantData: Set to the provided JSON string
    • + *
+ *

+ *

+ * Database Insertion: + * After construction, insert the match using the DAO: + * 

+     * // Get DAO instance
+     * MatchDao matchDao = AppDatabase.getDatabase(context).matchDao();
+     * 
+     * // Insert on background thread (required by Room)
+     * ExecutorService executor = Executors.newSingleThreadExecutor();
+     * executor.execute(() -> {
+     *     matchDao.insert(completedMatch);
+     *     
+     *     // Update UI on main thread
+     *     runOnUiThread(() -> {
+     *         Toast.makeText(context, "Match saved!", Toast.LENGTH_SHORT).show();
+     *         refreshMatchHistory();
+     *     });
+     * });
+     *
+ *

+ *

+ * Immutability Consideration: + * Once created and inserted, match data should generally be treated as immutable + * (historical record). If corrections are needed, consider whether to: + *

    + *
  • Update the existing match (rare, only for data corrections)
    • + *
  • Delete and recreate (for significant errors)
    • + *
  • Leave as-is and add a note field (preserves history)
    • + *
+ *

+ *

+ * Thread Safety: + * The constructor itself is thread-safe, but database insertion must occur on + * a background thread due to Room's main thread restrictions. + *

+ * + * @param timestamp The Unix epoch timestamp in milliseconds indicating when the match + * was completed. Should be positive and not in the future. Typically + * obtained via {@link System#currentTimeMillis()}. + * @param gameMode The identifier for the darts game variant played (e.g., "501", + * "301", "Cricket"). Should match one of the supported game modes. + * Must not be null or empty. + * @param playerCount The total number of players who participated in the match. + * Must be at least 1. Should match the number of entries in + * the participantData JSON array. + * @param participantData A JSON-formatted string containing an array of player + * performance objects.

+ * This entity class stores comprehensive information about each player in the squad, + * including their identity, profile picture, and career statistics. Player objects + * serve as the foundation for roster management, match participation tracking, and + * statistical analysis throughout the application. + *

+ *

+ * Room Database Entity: + * The {@code @Entity} annotation designates this class as a Room database table. + * Player records are stored in the "players" table and can be queried, inserted, + * updated, and managed using {@link com.aldo.apps.ochecompanion.database.dao.PlayerDao} + * methods. + *

+ *

+ * Data Structure: + * Each player record contains: + *

    + *
  • ID: Auto-generated unique identifier for database operations
    • + *
  • Username: Display name shown throughout the application
    • + *
  • Profile Picture URI: File path to the player's avatar image
    • + *
  • Career Average: Overall three-dart average across all matches
    • + *
  • Matches Played: Total count of completed matches
    • + *
+ *

+ *

+ * Player Lifecycle: + *

    + *
  1. Creation: Player is created via {@link com.aldo.apps.ochecompanion.AddPlayerActivity} + * with username and optional profile picture
    2. + *
  2. Roster Display: Players appear in the squad list on the main menu
    3. + *
  3. Match Participation: Players are selected for matches, their performance + * is recorded
    4. + *
  4. Statistics Update: Career stats are updated after each match completion
    5. + *
  5. Profile Editing: Username and picture can be modified through edit interface
    6. + *
+ *

+ *

+ * Usage Example: + * 

+ * // Create a new player
+ * Player newPlayer = new Player("John Doe", "/path/to/profile.jpg");
+ * newPlayer.careerAverage = 85.5;  // Optional initial stats
+ * newPlayer.matchesPlayed = 0;     // Starts at 0 by default
+ * 
+ * // Insert into database (background thread required)
+ * new Thread(() -> {
+ *     playerDao.insert(newPlayer);
+ *     // After insert, newPlayer.id contains the auto-generated ID
+ *     Log.d(TAG, "Player created with ID: " + newPlayer.id);
+ * }).start();
+ * 
+ * // Query and display players
+ * new Thread(() -> {
+ *     List<Player> allPlayers = playerDao.getAllPlayers();
+ *     runOnUiThread(() -> updateSquadUI(allPlayers));
+ * }).start();
+ * 
+ * // Update player statistics after match
+ * new Thread(() -> {
+ *     Player player = playerDao.getPlayerById(playerId);
+ *     player.matchesPlayed++;
+ *     player.careerAverage = calculateNewAverage(player, matchAverage);
+ *     playerDao.update(player);
+ * }).start();
+ *
+ *

+ *

+ * Profile Picture Management: + * Profile pictures are stored as URI strings pointing to local files in the app's + * private storage. This approach: + *

    + *
  • Avoids bloating the database with binary data
    • + *
  • Allows efficient image loading with Glide or Picasso
    • + *
  • Enables easy image replacement without database updates
    • + *
  • Supports null values for players without custom avatars (default avatar shown)
    • + *
+ *

+ *

+ * Career Statistics: + * The {@code careerAverage} field tracks the player's overall performance: + *

    + *
  • Calculated as three-dart average across all completed matches
    • + *
  • Updated after each match using weighted or running average algorithm
    • + *
  • Displayed in player cards and comparison views
    • + *
  • Used for skill-based matchmaking or handicap calculations
    • + *
+ *

+ *

+ * Match Count Tracking: + * The {@code matchesPlayed} counter: + *

    + *
  • Increments by 1 after each completed match
    • + *
  • Provides context for statistical significance (100 matches vs 5 matches)
    • + *
  • Enables filtering of experienced vs. new players
    • + *
  • Used in achievement and milestone tracking
    • + *
+ *

+ *

+ * Database Relationships: + * While this entity doesn't use explicit Room relations, players are referenced in: + *

    + *
  • {@link Match} entities via player IDs in participantData JSON
    • + *
  • RecyclerView adapters for squad and player selection displays
    • + *
  • Match creation flows where players are chosen from the roster
    • + *
+ *

+ *

+ * Thread Safety: + * All database operations on Player objects must be performed on background threads + * to comply with Room's threading requirements. Direct field access is not + * thread-safe; use proper synchronization if accessing from multiple threads. + *

+ *

+ * Validation Considerations: + * When creating or updating players, consider validating: + *

    + *
  • Username is not null or empty
    • + *
  • Username length is within reasonable bounds (e.g., 1-30 characters)
    • + *
  • Profile picture URI points to a valid, accessible file (if not null)
    • + *
  • Career average is non-negative and realistic (typically 0-120 for darts)
    • + *
  • Matches played count is non-negative
    • + *
+ *

+ *

+ * Future Enhancements: + * Consider adding these fields for expanded functionality: + *

    + *
  • wins/losses: Win-loss record tracking
    • + *
  • highestCheckout: Best finish/checkout across career
    • + *
  • favourite Game Mode: Most-played game variant
    • + *
  • createdDate: Timestamp when player was added to squad
    • + *
  • nickname: Alternative display name or alias
    • + *
  • skillRating: ELO or skill-based rating system
    • + *
+ *

+ *

+ * UI Integration: + * Players are displayed in various UI components: + *

    + *
  • {@link com.aldo.apps.ochecompanion.ui.adapter.MainMenuPlayerAdapter} - Squad roster grid
    • + *
  • {@link com.aldo.apps.ochecompanion.ui.view.PlayerItemView} - Individual player cards
    • + *
  • {@link com.aldo.apps.ochecompanion.AddPlayerActivity} - Player creation/editing form
    • + *
  • Match setup screens - Player selection for new matches
    • + *
+ *

+ *

+ * Performance Notes: + *

    + *
  • Player queries are fast due to indexed primary key (ID)
    • + *
  • Consider adding index on username for search functionality: + * {@code @Entity(indices = {@Index(value = {"username"})})}
    • + *
  • Profile picture URIs keep queries lightweight compared to storing images directly
    • + *
  • The simple schema makes inserts, updates, and queries efficient

+ * This field serves as the player's permanent identifier throughout the application + * and is used for all database operations, match participation tracking, and + * cross-referencing with match records. + *

+ *

+ * Auto-Generation: + * The {@code @PrimaryKey(autoGenerate = true)} annotation instructs Room to: + *

    + *
  • Automatically assign a unique ID when a new player is inserted
    • + *
  • Increment the ID value sequentially (1, 2, 3, ...)
    • + *
  • Update the Player object's ID field after successful insertion
    • + *
  • Use this ID as the primary key for update and query operations
    • + *
+ *

+ *

+ * Initial State: + * Before database insertion, this field has a default value of 0. After the + * player is inserted via {@link com.aldo.apps.ochecompanion.database.dao.PlayerDao#insert(Player)}, + * Room automatically populates this field with the generated ID value. + *

+ *

+ * Usage Examples: + * 

+     * // Before insertion
+     * Player player = new Player("Alice", "/path/to/pic.jpg");
+     * Log.d(TAG, "ID before insert: " + player.id);  // Output: 0
+     * 
+     * // Insert into database
+     * playerDao.insert(player);
+     * Log.d(TAG, "ID after insert: " + player.id);   // Output: 15 (or next available ID)
+     * 
+     * // Use ID to query specific player
+     * Player retrieved = playerDao.getPlayerById(player.id);
+     * 
+     * // Use ID in match participant data
+     * JSONObject participantData = new JSONObject();
+     * participantData.put("id", player.id);  // Reference this player in match
+     *
+ *

+ *

+ * Uniqueness and Permanence: + * SQLite's AUTOINCREMENT mechanism ensures: + *

    + *
  • No two players will ever have the same ID
    • + *
  • IDs are never reused, even after player deletion
    • + *
  • ID sequence continues across app restarts
    • + *
  • Historical match references remain valid
    • + *
+ *

+ *

+ * Cross-References: + * The player ID is stored in: + *

    + *
  • {@link Match#participantData} JSON arrays to link match participants
    • + *
  • Intent extras when navigating to {@link com.aldo.apps.ochecompanion.AddPlayerActivity} + * for editing
    • + *
  • Adapter item positions for click handling and UI updates
    • + *
+ *

+ *

+ * Integer Range: + * Using {@code int} supports up to 2,147,483,647 players, which is far beyond + * any realistic squad size. If migrating to multi-user cloud sync in the future, + * consider using {@code long} or UUID strings for globally unique identifiers. + *

+ * + * @see PrimaryKey + * @see com.aldo.apps.ochecompanion.database.dao.PlayerDao#getPlayerById(int) + * @see com.aldo.apps.ochecompanion.database.dao.PlayerDao#insert(Player) + */ + @PrimaryKey(autoGenerate = true) + public int id; + + /** + * The display name of the player shown throughout the application. + *

+ * This field stores the player's chosen name or alias, which appears in squad + * lists, player selection screens, match results, leaderboards, and all other + * UI components where the player is identified. The username serves as the + * primary human-readable identifier for each player. + *

+ *

+ * Display Locations: + * The username is prominently shown in: + *

    + *
  • Squad roster grid on the main menu
    • + *
  • Player cards in {@link com.aldo.apps.ochecompanion.ui.view.PlayerItemView}
    • + *
  • Match recap views showing participant names
    • + *
  • Player selection lists when creating new matches
    • + *
  • Edit player form in {@link com.aldo.apps.ochecompanion.AddPlayerActivity}
    • + *
  • Match history and statistical comparisons
    • + *
+ *

+ *

+ * Character Guidelines: + * While not enforced by the database schema, usernames should ideally: + *

    + *
  • Be non-null and non-empty (required for meaningful identification)
    • + *
  • Contain 1-30 characters (reasonable display length)
    • + *
  • Support Unicode characters (international names, emojis)
    • + *
  • Avoid leading/trailing whitespace (trim before saving)
    • + *
  • Be unique within the squad (not enforced, but recommended for UX)
    • + *
+ *

+ *

+ * Validation Example: + * 

+     * // Recommended validation before creating player
+     * private boolean isValidUsername(String username) {
+     *     if (username == null || username.trim().isEmpty()) {
+     *         showError("Username cannot be empty");
+     *         return false;
+     *     }
+     *     
+     *     String trimmed = username.trim();
+     *     if (trimmed.length() > 30) {
+     *         showError("Username too long (max 30 characters)");
+     *         return false;
+     *     }
+     *     
+     *     // Optional: Check for duplicate names
+     *     if (isUsernameTaken(trimmed)) {
+     *         showError("Username already exists in squad");
+     *         return false;
+     *     }
+     *     
+     *     return true;
+     * }
+     * 
+     * // Use validated username
+     * String validUsername = username.trim();
+     * Player player = new Player(validUsername, profilePicUri);
+     *
+ *

+ *

+ * Editing Usernames: + * Players can change their username via the edit interface: + * 

+     * // Load player for editing
+     * Player player = playerDao.getPlayerById(playerId);
+     * player.username = "New Name";
+     * playerDao.update(player);
+     * 
+     * // Note: Historical match records store username snapshots,
+     * // so past matches will still show the old name
+     *
+ *

+ *

+ * Database Storage: + * Stored as TEXT in SQLite, supporting any valid UTF-8 string. Room handles + * all string encoding/decoding automatically. Consider adding an index if + * implementing username search: + * 

+     * @Entity(tableName = "players",
+     *        indices = {@Index(value = {"username"}, name = "index_username")})
+     *
+ *

+ *

+ * Null Handling: + * This field should never be null in practice. If a player somehow has a null + * username, the UI should display a placeholder like "Unnamed Player" or + * "Player #[ID]" to prevent blank spaces or crashes. + *

+ *

+ * Case Sensitivity: + * SQLite comparisons are case-insensitive by default for ASCII characters. + * "John" and "john" are considered different usernames, but queries like + * {@code WHERE username = 'john'} will match "JOHN" or "John" unless + * {@code COLLATE BINARY} is specified. + *

+ *

+ * International Support: + * The field fully supports Unicode characters, allowing names in any language: + *

    + *
  • Chinese: 王明
    • + *
  • Arabic: محمد
    • + *
  • Cyrillic: Иван
    • + *
  • Emoji: John 🎯
    • + *
+ * Ensure UI fonts support these characters for proper display. + *

+ * + * @see com.aldo.apps.ochecompanion.AddPlayerActivity + * @see com.aldo.apps.ochecompanion.ui.view.PlayerItemView#bind(Player) + */ + public String username; + + /** + * The file system path (URI) to the player's profile picture image. + *

+ * This field stores a string representation of the file path where the player's + * avatar or profile picture is located in the app's private storage. Rather than + * storing image data directly in the database (which would bloat it), we store + * only the path reference and load the image on-demand using image loading + * libraries like Glide. + *

+ *

+ * Storage Strategy: + * Profile pictures are stored as local files because: + *

    + *
  • Database Efficiency: Avoiding BLOB storage keeps database + * size small and queries fast
    • + *
  • Image Loading: Glide and Picasso efficiently cache and + * load images from file paths
    • + *
  • Easy Replacement: Updating the image file doesn't require + * database updates
    • + *
  • Memory Management: Images aren't loaded into memory until + * needed for display
    • + *
+ *

+ *

+ * File Path Format: + * The URI typically follows this pattern: + * 

+     * /data/data/com.aldo.apps.ochecompanion/files/profile_pictures/player_123_20250128.jpg
+     *
+ * Or uses content URI format: + * 
+     * content://media/external/images/media/456
+     *
+ *

+ *

+ * Image Creation Flow: + * 

+     * // In AddPlayerActivity, after user crops image:
+     * File outputFile = new File(getFilesDir(), "profile_pictures/player_" + 
+     *                           System.currentTimeMillis() + ".jpg");
+     * 
+     * // Save cropped bitmap to file
+     * try (FileOutputStream out = new FileOutputStream(outputFile)) {
+     *     croppedBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
+     * }
+     * 
+     * // Store file path in player object
+     * String profilePicUri = outputFile.getAbsolutePath();
+     * Player player = new Player(username, profilePicUri);
+     * playerDao.insert(player);
+     *
+ *

+ *

+ * Loading Images with Glide: + * 

+     * // In PlayerItemView or adapter
+     * if (player.profilePictureUri != null && !player.profilePictureUri.isEmpty()) {
+     *     // Load custom profile picture
+     *     Glide.with(context)
+     *          .load(new File(player.profilePictureUri))
+     *          .placeholder(R.drawable.default_avatar)
+     *          .error(R.drawable.default_avatar)
+     *          .circleCrop()
+     *          .into(profileImageView);
+     * } else {
+     *     // Show default avatar
+     *     profileImageView.setImageResource(R.drawable.default_avatar);
+     * }
+     *
+ *

+ *

+ * Null and Empty Values: + * This field can be null or empty, indicating the player has no custom profile + * picture. In such cases, the UI should display a default avatar image: + *

    + *
  • Generic silhouette or icon
    • + *
  • Player's initials in a colored circle
    • + *
  • Default darts-themed avatar
    • + *
+ *

+ *

+ * File Management: + * Consider these file management practices: + *

    + *
  • Deletion: When a player is deleted or changes their picture, + * clean up old image files to prevent storage bloat
    • + *
  • Validation: Verify file exists before attempting to load
    • + *
  • Error Handling: Gracefully fall back to default avatar if + * file is missing or corrupted
    • + *
  • Format: Support common formats (JPEG, PNG, WebP)
    • + *
+ *

+ *

+ * File Cleanup Example: + * 

+     * // When updating player's profile picture
+     * Player player = playerDao.getPlayerById(playerId);
+     * String oldPicturePath = player.profilePictureUri;
+     * 
+     * // Set new picture
+     * player.profilePictureUri = newPicturePath;
+     * playerDao.update(player);
+     * 
+     * // Delete old picture file
+     * if (oldPicturePath != null && !oldPicturePath.isEmpty()) {
+     *     File oldFile = new File(oldPicturePath);
+     *     if (oldFile.exists()) {
+     *         oldFile.delete();
+     *     }
+     * }
+     *
+ *

+ *

+ * Image Optimization: + * Profile pictures should be: + *

    + *
  • Resized to reasonable dimensions (e.g., 500x500 pixels max)
    • + *
  • Compressed to balance quality and file size (JPEG quality 85-90)
    • + *
  • Cropped to square aspect ratio for consistent display
    • + *
  • Stored in app's private storage for security and isolation
    • + *
+ *

+ *

+ * Migration Consideration: + * If implementing cloud sync in the future, consider: + *

    + *
  • Uploading images to cloud storage (Firebase Storage, S3)
    • + *
  • Storing cloud URLs instead of local file paths
    • + *
  • Implementing offline caching with local fallbacks
    • + *
  • Supporting both local and remote image sources

+ * This field represents the player's overall skill level and consistency, + * calculated as the average score per three darts thrown throughout their + * entire match history. In darts, the three-dart average is the standard + * metric for measuring player performance and ability. + *

+ *

+ * Calculation Method: + * The career average is typically calculated using one of these approaches: + *

    + *
  • Running Average: (Total points scored) / (Total darts thrown / 3)
    • + *
  • Weighted Average: Recent matches weighted more heavily than older ones
    • + *
  • Match Average of Averages: Average of individual match averages
    • + *
+ *

+ *

+ * Update Example: + * 

+     * // After a match completes, update player's career average
+     * Player player = playerDao.getPlayerById(playerId);
+     * 
+     * // Method 1: Simple running average
+     * double totalPoints = player.careerAverage * player.matchesPlayed;
+     * totalPoints += matchAverage;  // Add this match's average
+     * player.matchesPlayed++;
+     * player.careerAverage = totalPoints / player.matchesPlayed;
+     * 
+     * // Method 2: Weighted average (70% old, 30% new)
+     * player.careerAverage = (player.careerAverage * 0.7) + (matchAverage * 0.3);
+     * player.matchesPlayed++;
+     * 
+     * playerDao.update(player);
+     *
+ *

+ *

+ * Typical Value Ranges: + * Three-dart averages in darts typically fall within these ranges: + *

    + *
  • 0-40: Beginner player, still learning fundamentals
    • + *
  • 40-60: Casual player, recreational skill level
    • + *
  • 60-80: Experienced player, competitive at local level
    • + *
  • 80-100: Advanced player, regional competitive level
    • + *
  • 100+: Professional or semi-professional level
    • + *
+ * World-class professionals maintain averages of 100-105+. + *

+ *

+ * Display Format: + * 

+     * // Format for display in UI
+     * String displayAverage = String.format(Locale.getDefault(), "%.1f", 
+     *                                      player.careerAverage);
+     * // Example output: "85.3"
+     * 
+     * // Or with context
+     * String statText = "Average: " + displayAverage + " ppd";
+     * // Example output: "Average: 85.3 ppd" (points per dart)
+     *
+ *

+ *

+ * Default Value: + * Initialized to 0.0 by default, indicating no match history yet. When displaying + * a player with 0.0 average and 0 matches played, consider showing placeholder + * text like "No matches yet" or "N/A" instead of "0.0". + *

+ *

+ * Statistical Significance: + * The reliability of the career average increases with match count: + * 

+     * if (player.matchesPlayed < 5) {
+     *     // Low sample size - show with disclaimer
+     *     displayText = player.careerAverage + " (limited data)";
+     * } else if (player.matchesPlayed < 20) {
+     *     // Moderate sample size
+     *     displayText = player.careerAverage + " (" + player.matchesPlayed + " matches)";
+     * } else {
+     *     // Reliable sample size
+     *     displayText = String.valueOf(player.careerAverage);
+     * }
+     *
+ *

+ *

+ * Comparison and Ranking: + * Used to rank players in leaderboards and skill-based groupings: + * 

+     * // Sort players by skill level
+     * List<Player> rankedPlayers = new ArrayList<>(allPlayers);
+     * Collections.sort(rankedPlayers, (p1, p2) -> 
+     *     Double.compare(p2.careerAverage, p1.careerAverage));  // Descending
+     * 
+     * // Find players in similar skill range for balanced matches
+     * double targetAverage = 75.0;
+     * double tolerance = 10.0;
+     * List<Player> similarSkill = players.stream()
+     *     .filter(p -> Math.abs(p.careerAverage - targetAverage) <= tolerance)
+     *     .collect(Collectors.toList());
+     *
+ *

+ *

+ * Data Integrity: + *

    + *
  • Should never be negative (minimum 0.0)
    • + *
  • Realistically shouldn't exceed 120 (theoretical maximum ~180)
    • + *
  • Should be 0.0 if matchesPlayed is 0
    • + *
  • Precision to 1-2 decimal places is sufficient
    • + *
+ *

+ *

+ * Alternative Metrics: + * Future enhancements might track additional averages: + *

    + *
  • First 9 darts average (excludes checkout phase)
    • + *
  • Per-game-mode averages (501 average, Cricket average)
    • + *
  • Recent form average (last 10 matches only)
    • + *
  • Peak average (highest match average achieved)
    • + *
+ *

+ * + * @see #matchesPlayed + * @see com.aldo.apps.ochecompanion.ui.view.PlayerItemView#bind(Player) + */ + public double careerAverage = 0.0; + + /** + * The total number of matches this player has completed. + *

+ * This counter tracks how many times the player has participated in and + * finished a match. It provides context for statistical significance, + * enables experience-based features, and supports achievement tracking. + * The count increases by 1 after each match completion, regardless of + * the outcome (win, loss, or placement in group matches). + *

+ *

+ * Update Pattern: + * 

+     * // After completing a match
+     * Player player = playerDao.getPlayerById(playerId);
+     *

+     * 
+     * playerDao.update(player);
+     *
+ *

+ *

+ * Default Value: + * Initialized to 0 by default, indicating a newly created player who hasn't + * yet participated in any matches. This is appropriate for new squad members + * added through {@link com.aldo.apps.ochecompanion.AddPlayerActivity}. + *

+ *

+ * Display Usage: + * 

+     * // Show experience level in player profile
+     * String experienceText;

+     *     showDisclaimer("Statistics based on limited match history");
+     * }
+     *
+ *

+ *

+ * Experience-Based Features: + * Match count enables various gameplay features: + *

    + *
  • Achievements: Unlock badges at 10, 50, 100, 500 matches
    • + *
  • Ranking Eligibility: Require minimum matches for leaderboards
    • + *
  • Skill Confidence: More matches = more reliable average
    • + *
  • Veteran Status: Display special icons for experienced players
    • + *
+ *

+ *

+ * Statistical Significance Example: + * 

+     * // Determine if statistics are reliable
+     * public String getSkillReliability(Player player) {
+     *     if (player.matchesPlayed == 0) {
+     *         return "No data";

+     *         return "Moderate data";
+     *     } else {
+     *         return "Reliable data";
+     *     }
+     * }
+     *
+ *

+ *

+ * Filtering and Queries: + * 

+     * // Get experienced players only
+     * @Query("SELECT * FROM players WHERE matchesPlayed >= 20 ORDER BY careerAverage DESC")
+     * List<Player> getExperiencedPlayers();
+     * 
+     * // Get players who need more matches for stats
+     * @Query("SELECT * FROM players WHERE matchesPlayed < 10")
+     * List<Player> getNewPlayers();
+     *
+ *

+ *

+ * Data Consistency: + * The match count should align with the player's career average: + *

    + *
  • If matchesPlayed = 0, careerAverage should be 0.0
    • + *
  • If careerAverage > 0, matchesPlayed should be > 0
    • + *
  • Both values should increase together after each match
    • + *
+ *

+ *

+ * Validation: + * 

+     * // Validate data consistency
+     * if (player.matchesPlayed < 0) {
+     *     Log.e(TAG, "Invalid match count: " + player.matchesPlayed);
+     *     player.matchesPlayed = 0;
+     * }
+     * 
+     * if (player.matchesPlayed == 0 && player.careerAverage != 0.0) {
+     *     Log.w(TAG, "Inconsistent data: 0 matches but non-zero average");
+     *     player.careerAverage = 0.0;
+     * }
+     *
+ *

+ *

+ * Match Type Consideration: + * This counter increments regardless of match type: + *

    + *
  • 1v1 head-to-head matches
    • + *
  • Group matches (3+ players)
    • + *
  • Solo practice sessions (if tracked)
    • + *
  • Tournament games
    • + *
+ * Consider adding separate counters for different match types if detailed + * tracking is needed. + *

+ *

+ * UI Presentation: + * Match count is typically displayed alongside the career average: + * 

+     * // In player card or profile
+     * averageText.setText(String.format("%.1f avg", player.careerAverage));
+     * matchesText.setText(player.matchesPlayed + " matches");
+     * 
+     * // Or combined
+     * statsText.setText(String.format("%.1f avg • %d matches", 
+     *                   player.careerAverage, player.matchesPlayed));
+     *
+ *

+ *

+ * Maximum Value: + * Using {@code int} supports up to 2,147,483,647 matches, which is essentially + * unlimited for any realistic usage. Even playing 10 matches per day, it would + * take 588,000+ years to overflow. + *

+ * + * @see #careerAverage + * @see com.aldo.apps.ochecompanion.database.objects.Match + */ + public int matchesPlayed = 0; + + /** + * Constructs a new Player with the specified username and profile picture. + *

+ * This constructor creates a player object ready for insertion into the database. + * The player's ID will be auto-generated by Room upon insertion, and statistical + * fields (careerAverage, matchesPlayed) are initialized to their default values + * of 0.0 and 0 respectively. + *

+ *

+ * Required Parameters: + *

    + *
  • username: The player's display name (should be non-null)
    • + *
  • profilePictureUri: Path to profile image (can be null for + * default avatar)
    • + *
+ *

+ *

+ * Usage Examples: + * 

+     * // Create player with custom profile picture
+     * String picturePath = "/data/data/app/files/profile_pics/player_123.jpg";
+     * Player player1 = new Player("John Doe", picturePath);

+     *     // careerAverage is 0.0, matchesPlayed is 0
+     * }).start();
+     *
+ *

+ *

+ * Parameter Validation: + * While the constructor doesn't enforce validation, it's recommended to validate + * parameters before construction: + * 

+     * // Validate before creating player
+     * String trimmedName = username.trim();
+     * if (trimmedName.isEmpty()) {
+     *     throw new IllegalArgumentException("Username cannot be empty");

+     * 
+     * // Validate profile picture path if provided
+     * if (profilePictureUri != null && !profilePictureUri.isEmpty()) {
+     *     File pictureFile = new File(profilePictureUri);
+     *     if (!pictureFile.exists()) {
+     *         Log.w(TAG, "Profile picture file does not exist: " + profilePictureUri);
+     *         // Decide whether to use null or keep invalid path

+     * }
+     * 
+     * // Create player with validated data
+     * Player player = new Player(trimmedName, profilePictureUri);
+     *
+ *

+ *

+ * Field Initialization: + * After construction, the player object has these values: + *

    + *
  • id: 0 (will be auto-generated on insert)
    • + *
  • username: Set to provided value
    • + *
  • profilePictureUri: Set to provided value (can be null)
    • + *
  • careerAverage: 0.0 (default initialization)
    • + *
  • matchesPlayed: 0 (default initialization)
    • + *
+ *

+ *

+ * Typical Creation Flow: + * 

+     * // In AddPlayerActivity after user completes form
+     * 
+     * // 1. Get username from input
+     * String username = usernameEditText.getText().toString().trim();
+     * 
+     * // 2. Get profile picture path (or null if no picture selected)
+     * String profilePicUri = (croppedImageFile != null) ? 
+     *                        croppedImageFile.getAbsolutePath() : null;
+     * 
+     * // 3. Create player object
+     * final Player newPlayer = new Player(username, profilePicUri);
+     * 
+     * // 4. Insert into database on background thread
+     * new Thread(() -> {
+     *     playerDao.insert(newPlayer);
+     *     
+     *     runOnUiThread(() -> {
+     *         Toast.makeText(this, "Player added to squad!", Toast.LENGTH_SHORT).show();
+     *         finish();  // Return to main menu
+     *     });
+     * }).start();
+     *
+ *

+ *

+ * Alternative Construction Approach: + * For more complex initialization, create and then modify: + * 

+     * // Create base player
+     * Player player = new Player("Alice Johnson", profilePath);
+     * 
+     * // Set initial statistics if importing from another system
+     * player.careerAverage = 78.5;  // Imported average
+     * player.matchesPlayed = 42;     // Imported match count
+     * 
+     * // Insert with pre-populated stats
+     * playerDao.insert(player);
+     *
+ *

+ *

+ * Null Handling: + * The constructor accepts null for profilePictureUri, which is valid and indicates + * no custom profile picture. The UI should display a default avatar in this case. + * However, passing null for username will create a player with a null name, which + * should be avoided as it causes UI issues. + *

+ *

+ * Database Insertion: + * Remember that the Player object is not persisted until explicitly inserted: + * 

+     * Player player = new Player("Tom", null);
+     * // player exists only in memory at this point
+     * 
+     * playerDao.insert(player);
+     * // now player is persisted in database and player.id is set
+     *
+ *

+ *

+ * Room Constructor Requirements: + * Room requires this constructor to instantiate Player objects when reading from + * the database. The constructor parameters must match the entity fields (excluding + * the auto-generated ID and default-initialized fields). + *

+ * + * @param username The display name for the player. Should be non-null, non-empty, + * and ideally 1-30 characters. Supports Unicode for international + * names. This will be shown throughout the app in player lists, + * match results, and statistics. + * @param profilePictureUri The file system path or content URI to the player's + * profile picture. Can be null or empty string, in which + * case the UI will display a default avatar. Should point + * to a valid image file if provided. + * @see #id + * @see #username + * @see #profilePictureUri + * @see #careerAverage + * @see #matchesPlayed + * @see com.aldo.apps.ochecompanion.AddPlayerActivity + * @see com.aldo.apps.ochecompanion.database.dao.PlayerDao#insert(Player) + */ + public Player(final String username, final String profilePictureUri) { + // Initialize the player's identity fields with provided values + // Statistical fields (careerAverage, matchesPlayed) use their default values (0.0 and 0) + // The id field remains 0 and will be auto-generated by Room upon database insertion + this.username = username; + this.profilePictureUri = profilePictureUri; + } + + + + /** + * Parcelable constructor used by the CREATOR to reconstruct the object. + * @param in The Parcel containing the serialized data. + */ + protected Player(final Parcel in) { + id = in.readInt(); + username = in.readString(); + profilePictureUri = in.readString(); + careerAverage = in.readDouble(); + matchesPlayed = in.readInt(); + } + + /** + * Required CREATOR field for Parcelable implementation. + */ + public static final Creator CREATOR = new Creator() { + @Override + public Player createFromParcel(Parcel in) { + return new Player(in); + } + + @Override + public Player[] newArray(int size) { + return new Player[size]; + } + }; + + @Override + public int describeContents() { + return 0; + } + + /** + * Flattens the object into a Parcel. + */ + @Override + public void writeToParcel(Parcel dest, int flags) { + dest.writeInt(id); + dest.writeString(username); + dest.writeString(profilePictureUri); + dest.writeDouble(careerAverage); + dest.writeInt(matchesPlayed); + } + + /** + * Returns a string representation of this Player object for debugging and logging. + *

+ * Field Inclusion: + * All fields are included in the string representation: + *

    + *
  • id: Shows the database ID (0 before insertion)
    • + *
  • username: Enclosed in single quotes to show exact value

  • profilePictureUri: Full path string in single quotes
    • + *
  • careerAverage: Shown with decimal precision

+     *
+ *

+ *

+ * Not for UI Display: + * This method is NOT intended for user-facing text. For UI display, format + * individual fields appropriately: + *

+     *                   player.careerAverage, player.matchesPlayed));
+     *
+ *

+ *

+ * Logging Best Practices: + * 

+     * // Verbose logging for detailed debugging
+     * Log.v(TAG, "Player loaded: " + player);
+     * 
+     * // Debug logging for development
+     * Log.d(TAG, "Updated player stats: " + player);
+     * 
+     * // Error logging with context

+     * // Conditional logging
+     * if (BuildConfig.DEBUG) {
+     *     Log.d(TAG, "All players: " + players.toString());
+     * }
+     *
+ *

+ *

+ * Performance Note: + * String concatenation in toString() creates temporary objects. Avoid calling + * toString() in performance-critical loops unless necessary. For production builds, + * consider using Timber or similar libraries that can be disabled in release builds. + *

+ *

+ * Privacy Consideration: + * Be cautious when logging player data in production: + *

    + *
  • Username is personally identifiable information

  • Profile picture paths might reveal device file structure
    • + *
  • Consider redacting sensitive info in production logs
    • + *
  • Ensure logs don't leak to crash reporting services unintentionally

    + *
  • The class is mutable in that it stores player references, but doesn't provide + * methods to add/remove players after construction

+ *

+ * Position Indexing: + * Positions are zero-based indices: + *

    + *
  • Dark semi-transparent mask (85% opacity Midnight Black) covers the entire view

  • Transparent square cutout in the center shows the crop area

  • Crop box is 80% of the view's width, maintaining a square aspect ratio

  • Automatically centers the crop box within the view

The outer rectangle (entire view) is drawn clockwise, while the + * inner rectangle (crop area) is drawn counter-clockwise. This winding direction technique + * causes the inner rectangle to subtract from the outer one, creating a transparent window. + *

+ * This method provides a structured way to update the button's subtitle by combining + * game mode and rules information into a formatted string. It handles the concatenation + * logic and properly formats the output with a separator between mode and rules. + *

+ *

+ * Formatting Behavior: + *

    + *
  • If rules are provided: Displays "[MODE] - [RULES]" (e.g., "501 - DOUBLE OUT")
    • + *
  • If rules are empty/null: Displays only "[MODE]" (e.g., "501")
    • + *
+ *

+ *

+ * Example Usage: + * 

+     * // With rules
+     * button.updateContext("501", "Double Out");
+     * // Results in: "501 - DOUBLE OUT"
+     * 
+     * // Without rules
+     * button.updateContext("301", null);
+     * // Results in: "301"
+     * 
+     * button.updateContext("Cricket", "");
+     * // Results in: "CRICKET"
+     *
+ *

+ *

+ * Advantages over setSubText: + *

    + *
  • Provides consistent formatting across the app
