* AddPlayerActivity manages the creation and editing of player profiles in the Oche Companion application.
* <p>
* This activity provides a comprehensive user interface for managing player information including:
* <ul>
* <li>Creating new player profiles with username and profile picture</li>
* <li>Editing existing player profiles</li>
* <li>Advanced image cropping functionality with pan and pinch-to-zoom controls</li>
* <li>Saving profile pictures to internal storage</li>
* </ul>
* </p>
* <p>
* The activity features two distinct UI modes:
* <ul>
* <li><strong>Form Mode:</strong> Standard profile editing with username input and profile picture selection</li>
* <li><strong>Crop Mode:</strong> Interactive image cropping interface with gesture controls for precise framing</li>
* </ul>
* </p>
* <p>
* <strong>Image Processing Pipeline:</strong>
* <ol>
* <li>User selects an image from their gallery</li>
* <li>Activity switches to Crop Mode with the selected image</li>
* <li>User can pan (drag) and pinch-to-zoom to frame the desired area</li>
* <li>A square crop overlay shows the final cutout area</li>
* <li>Upon confirmation, the cropped image is saved to internal storage</li>
* <li>Activity returns to Form Mode with the cropped image displayed</li>
* </ol>
* </p>
* <p>
* <strong>Usage:</strong>
* 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.
* </p>

* <li><strong>ImageView Fit-Center Scale:</strong> The automatic scaling applied by Android to fit the image in the view</li>

* <li>Calculate the fit-center scale applied by the ImageView</li>
* <li>Combine fit-center scale with user's manual zoom scale</li>
* <li>Determine the current position of the bitmap in screen space</li>
* <li>Get the crop box coordinates from the overlay</li>
* <li>Transform screen coordinates to bitmap pixel coordinates</li>

/**
* The main Room database class for the Oche Companion darts application.
* <p>
* 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.
* </p>
* <p>
* <strong>Room Database Architecture:</strong>
* Room is Android's SQLite object-relational mapping (ORM) library that provides
* an abstraction layer over SQLite, offering:
* <ul>
* <li>Compile-time SQL query verification</li>
* <li>Convenient annotation-based entity and DAO definitions</li>
* <li>Automatic conversion between SQLite and Java/Kotlin objects</li>
* <li>LiveData and Flow support for reactive UI updates</li>
* <li>Migration support for database schema changes</li>
* </ul>
* </p>
* <p>
* <strong>Database Entities:</strong>
* This database manages two primary tables:
* <ul>
* <li><strong>players:</strong> Squad roster with player profiles and career statistics
* (defined by {@link Player} entity)</li>
* <li><strong>matches:</strong> Completed match records with participant data and results
* (defined by {@link Match} entity)</li>
* </ul>
* </p>
* <p>
* <strong>Database Access Objects (DAOs):</strong>
* Database operations are performed through specialized DAO interfaces:
* <ul>
* <li>{@link PlayerDao}: CRUD operations for player management (insert, update, query)</li>
* <li>{@link MatchDao}: Match record operations (insert, query all, query last match)</li>
* </ul>
* </p>
* <p>
* <strong>Singleton Pattern Implementation:</strong>
* The class uses the thread-safe double-checked locking pattern to ensure a single
* database instance. This approach:
* <ul>
* <li>Prevents multiple database connections that waste resources</li>
* <li>Ensures data consistency across the application</li>
* <li>Reduces memory overhead by sharing one connection pool</li>
* <li>Thread-safe initialization prevents race conditions</li>
* </ul>
* </p>
* <p>
* <strong>Usage Example:</strong>
* <pre>
* // 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&lt;Player&gt; allPlayers = playerDao.getAllPlayers();
*
* // Insert a match
* Match match = new Match(System.currentTimeMillis(), "501", 2, participantJson);
* matchDao.insert(match);
*
* // Get recent matches
* List&lt;Match&gt; recentMatches = matchDao.getAllMatches();
* }).start();
* </pre>
* </p>
* <p>
* <strong>Database Versioning:</strong>
* Currently at version 2, indicating one schema change since initial creation.
* Version increments are required when:
* <ul>
* <li>Adding or removing tables</li>
* <li>Adding or removing columns</li>
* <li>Changing column types or constraints</li>
* <li>Modifying primary keys or indices</li>
* </ul>
* 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.
* </p>
* <p>
* <strong>Migration Strategy:</strong>
* For production releases, replace destructive migration with proper migration paths:
* <pre>
* 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();
* </pre>
* </p>
* <p>
* <strong>Database File Location:</strong>
* The SQLite database file "oche_companion_db" is stored in the app's private
* storage at:
* <pre>
* /data/data/com.aldo.apps.ochecompanion/databases/oche_companion_db
* </pre>
* This location is:
* <ul>
* <li>Private to the application (other apps cannot access)</li>
* <li>Automatically backed up with Auto Backup (if enabled)</li>
* <li>Cleared when the app is uninstalled</li>
* <li>Accessible for inspection via Android Studio Database Inspector</li>
* </ul>
* </p>
* <p>
* <strong>Schema Export:</strong>
* The {@code exportSchema = false} setting disables automatic schema JSON export.
* For production apps, consider enabling this:
* <pre>
* @Database(entities = {...}, version = 2, exportSchema = true)
* </pre>
* And specify the export directory in build.gradle:
* <pre>
* android {
* defaultConfig {
* javaCompileOptions {
* annotationProcessorOptions {
* arguments += ["room.schemaLocation": "$projectDir/schemas"]
* }
* }
* }
* }
* </pre>
* This creates version-controlled schema files for tracking changes and testing migrations.
* </p>
* <p>
* <strong>Threading Requirements:</strong>
* Room enforces that database operations occur on background threads:
* <ul>
* <li>Attempting database operations on the main thread throws {@link IllegalStateException}</li>
* <li>Use {@link Thread}, {@link java.util.concurrent.ExecutorService}, or Kotlin coroutines</li>
* <li>UI updates after database operations must use {@code runOnUiThread()} or similar</li>
* <li>Consider using LiveData or Flow for automatic thread handling and UI updates</li>
* </ul>
* </p>
* <p>
* <strong>Database Inspection:</strong>
* For debugging, you can inspect the database using:
* <ul>
* <li><strong>Android Studio Database Inspector:</strong> View > Tool Windows > Database Inspector</li>
* <li><strong>ADB:</strong> {@code adb shell} and SQLite command line</li>
* <li><strong>Third-party tools:</strong> DB Browser for SQLite (requires root or backup)</li>
* </ul>
* </p>
* <p>
* <strong>Performance Optimization:</strong>
* <ul>
* <li>Database queries are optimized with SQLite indices on primary keys</li>
* <li>Connection pooling is handled automatically by Room</li>
* <li>Consider adding custom indices for frequently queried columns:
* <pre>@Entity(indices = {@Index(value = {"username"})})</pre></li>
* <li>Use transactions for batch operations to improve performance</li>
* <li>Avoid N+1 query problems by using JOIN queries or @Relation</li>
* </ul>
* </p>
* <p>
* <strong>Testing:</strong>
* For unit testing, create an in-memory database:
* <pre>
* @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();
* }
* </pre>
* </p>
* <p>
* <strong>Data Backup and Restore:</strong>
* Consider implementing backup functionality:
* <ul>
* <li>Export database to external storage or cloud</li>
* <li>Use Android's Auto Backup for automatic cloud backup</li>
* <li>Provide manual export/import for user control</li>
* <li>Validate data integrity after restore operations</li>
* </ul>
* </p>
* <p>
* <strong>Security Considerations:</strong>
* <ul>
* <li>Database is stored in app's private directory (secure by default)</li>
* <li>For sensitive data, consider using SQLCipher for encryption</li>
* <li>Be cautious when exporting database (may contain user data)</li>
* <li>Validate and sanitize all data before insertion to prevent SQL injection
* (Room's parameterized queries provide protection)</li>
* </ul>
* </p>
* <p>
* <strong>Future Enhancements:</strong>
* Consider these improvements for future versions:
* <ul>
* <li>Add proper migration strategies instead of destructive migration</li>
* <li>Implement database encryption with SQLCipher</li>
* <li>Add support for exporting/importing data</li>
* <li>Create additional entities for tournaments, achievements, settings</li>
* <li>Implement multi-user support with user profiles table</li>
* <li>Add full-text search capabilities with FTS tables</li>
* </ul>

* 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&lt;Player&gt; squad = playerDao.getAllPlayers();
*
* // Update player stats
* Player player = playerDao.getPlayerById(5);

* playerDao.update(player);
* }
*
* // Update UI on main thread
* runOnUiThread(() -> updateSquadDisplay(squad));
* }).start();
* </pre>
* </p>
* <p>
* <strong>Thread Safety:</strong>
* 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}.
* </p>
* <p>
* <strong>DAO Lifecycle:</strong>
* The DAO instance is created once by Room and can be cached and reused:
* <pre>
* // 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);
* </pre>
* </p>
* <p>
* <strong>Common Usage Patterns:</strong>
* <pre>
* // Pattern 1: Simple query and UI update
* ExecutorService executor = Executors.newSingleThreadExecutor();
* executor.execute(() -> {
* List&lt;Player&gt; 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();
* </pre>
* </p>
* <p>
* <strong>Alternative Reactive Approaches:</strong>
* Consider using LiveData or Flow for automatic UI updates:
* <pre>
* // If PlayerDao had LiveData support:
* // @Query("SELECT * FROM players ORDER BY username ASC")
* // LiveData&lt;List&lt;Player&gt;&gt; getAllPlayersLive();
*
* // Usage in Activity/Fragment:
* db.playerDao().getAllPlayersLive().observe(this, players -> {
* // UI automatically updates when data changes
* adapter.setPlayers(players);
* });
* </pre>
* </p>
* <p>
* <strong>Error Handling:</strong>
* <pre>
* new Thread(() -> {
* try {
* playerDao.insert(player);
* runOnUiThread(() -> showSuccess());
* } catch (SQLiteConstraintException e) {
* Log.e(TAG, "Constraint violation", e);
* runOnUiThread(() -> showError("Failed to save player"));
* } catch (Exception e) {
* Log.e(TAG, "Database error", e);
* runOnUiThread(() -> showError("Unexpected error"));

/**
* Provides access to Match-related database operations.
* <p>
* This abstract method is implemented by Room at compile time, returning an
* instance of the {@link MatchDao} interface. The DAO provides methods for
* storing and retrieving match records, enabling match history tracking and
* statistical analysis.
* </p>
* <p>
* <strong>Available Operations:</strong>
* The returned MatchDao provides these methods:
* <ul>
* <li>{@link MatchDao#insert(Match)} - Save completed match to history</li>
* <li>{@link MatchDao#getAllMatches()} - Retrieve all matches ordered by most recent</li>
* <li>{@link MatchDao#getLastMatch()} - Get the most recently completed match</li>
* </ul>
* </p>
* <p>
* <strong>Usage Example:</strong>
* <pre>
* // Get database instance
* AppDatabase db = AppDatabase.getDatabase(context);
*
* // Get MatchDao
* MatchDao matchDao = db.matchDao();
*
* // Save completed match (background thread)
* new Thread(() -> {
* // Create match record with participant data
* String participantJson = buildParticipantData(players, scores);
* Match match = new Match(
* System.currentTimeMillis(),
* "501",
* 2,
* participantJson
* );
*
* // Insert into database
* matchDao.insert(match);
*
* // Get match history for display
* List&lt;Match&gt; allMatches = matchDao.getAllMatches();
*
* // Update UI with latest match
* Match lastMatch = matchDao.getLastMatch();
* runOnUiThread(() -> displayMatchRecap(lastMatch));
* }).start();
* </pre>
* </p>
* <p>
* <strong>Match History Display:</strong>
* <pre>
* // Load match history for main menu
* new Thread(() -> {
* List&lt;Match&gt; recentMatches = db.matchDao().getAllMatches();
*
* runOnUiThread(() -> {
* if (recentMatches.isEmpty()) {
* // Show empty state - no matches played yet
* showEmptyMatchHistory();
* } else {
* // Display most recent match in recap view
* Match lastMatch = recentMatches.get(0);
* matchRecapView.setMatch(lastMatch);
* }
* });
* }).start();
* </pre>
* </p>
* <p>
* <strong>Match Completion Flow:</strong>
* <pre>
* // After match ends, save to database
* private void saveMatchResult(List&lt;Player&gt; players, Map&lt;Player, Score&gt; scores) {
* new Thread(() -> {
* // Build participant data JSON
* JSONArray participants = new JSONArray();
* for (Player player : players) {
* JSONObject data = new JSONObject();
* data.put("id", player.id);
* data.put("username", player.username);
* data.put("rank", scores.get(player).rank);
* data.put("average", scores.get(player).average);

*
* // Create and save match
* Match match = new Match(

* </pre>
* </p>
* <p>
* <strong>Thread Safety:</strong>
* 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.
* </p>
* <p>
* <strong>Performance Considerations:</strong>
* <ul>
* <li>getAllMatches() loads all match records - consider pagination for users
* with hundreds of matches</li>
* <li>getLastMatch() uses LIMIT 1 for efficient querying</li>
* <li>Matches are ordered by timestamp DESC for chronological display</li>
* <li>Consider adding date range queries for filtering match history</li>
* </ul>
* </p>
* <p>
* <strong>Statistical Queries:</strong>
* <pre>
* // Get match history for analysis
* new Thread(() -> {
* List&lt;Match&gt; allMatches = db.matchDao().getAllMatches();
*
* // Calculate statistics
* int totalMatches = allMatches.size();
* Map&lt;String, Integer&gt; gameModeCount = new HashMap&lt;&gt;();
*
* for (Match match : allMatches) {
* gameModeCount.merge(match.gameMode, 1, Integer::sum);
* }
*
* // Display stats
* runOnUiThread(() -> showStatistics(totalMatches, gameModeCount));
* }).start();
* </pre>
* </p>
* <p>
* <strong>DAO Lifecycle:</strong>
* The DAO instance can be cached and reused throughout the app:
* <pre>
* // Cache in Application class or repository
* private MatchDao matchDao;
*
* public MatchDao getMatchDao() {
* if (matchDao == null) {

/**
* The singleton instance of the AppDatabase.
* <p>
* 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.
* </p>
* <p>
* <strong>Volatile Keyword:</strong>
* The volatile modifier guarantees:
* <ul>
* <li>Happens-before relationship: Writes to INSTANCE are visible to all threads</li>
* <li>Prevents instruction reordering that could break double-checked locking</li>
* <li>Ensures thread sees the fully constructed object, not a partially initialized one</li>
* <li>No caching of the variable value in CPU registers</li>
* </ul>
* </p>
* <p>
* <strong>Initialization State:</strong>
* <ul>
* <li><strong>null:</strong> Before first call to {@link #getDatabase(Context)}</li>
* <li><strong>non-null:</strong> After database is created, remains set for app lifetime</li>
* </ul>
* </p>
* <p>
* <strong>Memory Lifecycle:</strong>
* The database instance is retained in memory for the lifetime of the application
* process. It will be garbage collected only when:
* <ul>
* <li>The app process is terminated by Android</li>
* <li>The app is killed by the user</li>
* <li>System needs to reclaim memory and kills the app's process</li>
* </ul>
* </p>
* <p>
* <strong>Testing Considerations:</strong>
* For unit tests, you may need to reset the singleton:
* <pre>
* // 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;
* }
* }
* </pre>
* </p>
* <p>
* <strong>Why Singleton:</strong>
* Using a singleton for the database instance provides:
* <ul>
* <li>Single connection pool shared across the app</li>
* <li>Consistent data state across all components</li>
* <li>Reduced memory overhead (no duplicate instances)</li>
* <li>Prevention of conflicting database access</li>
* <li>Simplified database access (no need to pass instance around)</li>
* </ul>
* </p>
* <p>
* <strong>Thread Safety Analysis:</strong>
* The volatile keyword combined with synchronized block in {@link #getDatabase(Context)}
* ensures thread-safe lazy initialization:
* <pre>
* // 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
* </pre>
* </p>

* @see RoomDatabase

/**
* Gets the singleton instance of the AppDatabase, creating it if necessary.
* <p>
* 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.).
* </p>
* <p>
* <strong>Double-Checked Locking Pattern:</strong>
* The implementation uses two null checks to optimize performance:
* <ol>
* <li><strong>First check (unsynchronized):</strong> Fast path for when instance exists.
* Avoids expensive synchronization on subsequent calls.</li>
* <li><strong>Synchronized block:</strong> Ensures only one thread creates the instance.
* Prevents race conditions during initialization.</li>
* <li><strong>Second check (synchronized):</strong> Prevents multiple creation if several
* threads passed the first check simultaneously.</li>
* </ol>
* </p>
* <p>
* <strong>Usage Example:</strong>
* <pre>
* // 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&lt;Player&gt; 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);
* </pre>
* </p>
* <p>
* <strong>Context Parameter:</strong>
* The method accepts any Context but internally uses {@code context.getApplicationContext()}
* to avoid memory leaks. This means:
* <ul>
* <li>Activity context is safe to pass (converted to app context)</li>
* <li>Fragment context is safe to pass (converted to app context)</li>
* <li>Application context is ideal but not required</li>
* <li>No risk of leaking Activity or Fragment references</li>
* </ul>
* </p>
* <p>
* <strong>Database Builder Configuration:</strong>
* The database is created with these settings:
* <pre>
* 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();
* </pre>
* </p>
* <p>
* <strong>Destructive Migration Strategy:</strong>
* The {@code fallbackToDestructiveMigration()} setting means:
* <ul>
* <li><strong>Advantage:</strong> No need to write migration code during development</li>
* <li><strong>Disadvantage:</strong> All data is lost when database version changes</li>
* <li><strong>Development:</strong> Acceptable for testing and iteration</li>
* <li><strong>Production:</strong> Should be replaced with proper migrations:
* <pre>.addMigrations(MIGRATION_1_2, MIGRATION_2_3)</pre>
* </li>
* </ul>
* </p>
* <p>
* <strong>First Call Initialization:</strong>
* On the first call, this method will:
* <ol>
* <li>Create the SQLite database file in app's private storage</li>
* <li>Create all tables defined by entity classes (players, matches)</li>
* <li>Set up indices and constraints</li>
* <li>Initialize Room's internal structures</li>
* <li>Return the ready-to-use database instance</li>
* </ol>
* 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.
* </p>
* <p>
* <strong>Subsequent Calls:</strong>
* After initialization, subsequent calls:
* <ul>
* <li>Return immediately (fast path, no synchronization)</li>
* <li>No database access or initialization overhead</li>
* <li>Thread-safe from all threads</li>
* <li>Essentially free performance-wise</li>
* </ul>
* </p>
* <p>
* <strong>Thread Safety Guarantee:</strong>
* <pre>
* // 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
* </pre>
* </p>
* <p>
* <strong>Best Practices:</strong>
* <ul>
* <li>Call early in app lifecycle (Application.onCreate()) to avoid first-call delay</li>
* <li>Use application context when possible for clarity</li>
* <li>No need to cache the returned instance (method is fast)</li>
* <li>Safe to call repeatedly throughout the app</li>
* </ul>
* </p>
* <p>
* <strong>Proactive Initialization:</strong>
* <pre>
* public class OcheCompanionApplication extends Application {
* @Override
* public void onCreate() {
* super.onCreate();
*
* // Initialize database early to avoid delay on first access
* AppDatabase.getDatabase(this);
* }
* }
* </pre>
* </p>
* <p>
* <strong>Error Handling:</strong>
* In rare cases, database creation might fail due to:
* <ul>
* <li>Insufficient storage space</li>
* <li>Corrupted database file</li>
* <li>File system errors</li>
* </ul>
* Room will throw RuntimeException in these cases. Consider adding error handling:
* <pre>
* 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.
* }
* </pre>
* </p>
*
* @param context The application context used to create the database. While any
* Context type can be passed (Activity, Fragment, Service, etc.),
* the method internally uses {@code context.getApplicationContext()}
* to prevent memory leaks. Must not be null.
* @return The singleton AppDatabase instance, fully initialized and ready for use.
* Never returns null. The same instance is returned on all subsequent calls.
* @throws IllegalArgumentException if context is null (thrown by Room.databaseBuilder)
* @throws RuntimeException if database creation fails due to filesystem or other errors
* @see Room#databaseBuilder(Context, Class, String)
* @see RoomDatabase.Builder#fallbackToDestructiveMigration()

/**
* Data Access Object (DAO) interface for performing database operations on Match entities.
* <p>
* 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.
* </p>
* <p>
* <strong>Room Database Integration:</strong>
* 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.
* </p>
* <p>
* <strong>Key Features:</strong>
* <ul>
* <li>Insert completed match records into the database</li>
* <li>Retrieve complete match history sorted by most recent first</li>
* <li>Query the last played match for dashboard/recap displays</li>
* <li>Thread-safe operations managed by Room</li>
* </ul>
* </p>
* <p>
* <strong>Thread Safety:</strong>
* 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).
* </p>
* <p>
* <strong>Usage Example:</strong>
* <pre>
* // 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();
* </pre>
* </p>
* <p>
* <strong>Database Table:</strong>
* This DAO operates on the "matches" table, which is defined by the {@link Match}
* entity class with its {@code @Entity} annotation.
* </p>
*
* @see Match
* @see Dao
* @see com.aldo.apps.ochecompanion.database.AppDatabase

* Inserts a completed match record into the database.
* <p>
* 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.
* </p>
* <p>
* <strong>Threading:</strong>
* 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).
* </p>
* <p>
* <strong>Transaction Behavior:</strong>
* By default, Room wraps this operation in a transaction. If the insert fails, the
* transaction will be rolled back, maintaining database consistency.
* </p>
* <p>
* <strong>Conflict Strategy:</strong>
* 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.
* </p>
* <p>
* <strong>Return Value:</strong>
* While this method returns void, the {@code @Insert} annotation can be configured
* to return:
* <ul>
* <li>{@code long} - The row ID of the newly inserted match</li>
* <li>{@code Long} - Same as above, but nullable</li>
* <li>{@code long[]} or {@code Long[]} - For bulk inserts</li>
* <li>{@code List<Long>} - Alternative for bulk inserts</li>

* // Handle insert failure
* Log.e(TAG, "Failed to insert match", e);

*
* @param match The Match entity to persist. Must not be null. Should contain all

* </p>
* <p>
* <strong>SQL Query:</strong>
* Executes: {@code SELECT * FROM matches ORDER BY timestamp DESC}
* </p>
* <p>
* <strong>Sorting:</strong>
* Matches are ordered by the "timestamp" field in descending order (DESC), meaning:

* </p>
* <p>
* <strong>Performance Considerations:</strong>
* <ul>
* <li>This query loads ALL matches into memory, which could be problematic for
* large datasets (thousands of matches)</li>
* <li>Consider using pagination (e.g., {@code LIMIT} and {@code OFFSET}) for better
* performance with large history</li>
* <li>Consider using LiveData or Flow for reactive updates</li>

/**
* Data Access Object (DAO) interface for performing database operations on Player entities.
* <p>
* This interface defines the contract for accessing and manipulating player data in the
* Room database. It provides comprehensive CRUD (Create, Read, Update) operations for
* managing the squad roster. Room generates the implementation of this interface at
* compile time, handling all SQL generation, cursor management, and data mapping.
* </p>
* <p>
* <strong>Room Database Integration:</strong>
* The {@code @Dao} annotation marks this as a Room DAO interface. Room's annotation
* processor will automatically generate an implementation class that handles:
* <ul>
* <li>SQL query construction and execution</li>
* <li>SQLite connection management</li>
* <li>Result cursor handling and mapping to Player objects</li>
* <li>Transaction management and error handling</li>
* </ul>
* </p>
* <p>
* <strong>Key Features:</strong>
* <ul>
* <li><strong>Insert:</strong> Add new players to the squad roster</li>
* <li><strong>Update:</strong> Modify existing player information (username, profile picture, stats)</li>
* <li><strong>Query by ID:</strong> Retrieve a specific player for editing</li>
* <li><strong>Query All:</strong> Get the complete squad list, alphabetically sorted</li>
* </ul>
* </p>
* <p>
* <strong>Thread Safety:</strong>
* All database operations must be performed on a background thread to avoid blocking
* the main UI thread. Room enforces this requirement by default and will throw an
* {@link IllegalStateException} if database operations are attempted on the main thread
* (unless explicitly configured to allow it, which is not recommended).
* </p>
* <p>
* <strong>Usage Example:</strong>
* <pre>
* // Get DAO instance from database
* PlayerDao playerDao = AppDatabase.getDatabase(context).playerDao();
*
* // Insert a new player (background thread)
* new Thread(() -> {
* Player newPlayer = new Player("John Doe", "/path/to/pic.jpg");
* playerDao.insert(newPlayer);
* }).start();
*
* // Query all players (background thread)
* new Thread(() -> {
* List&lt;Player&gt; players = playerDao.getAllPlayers();
* runOnUiThread(() -> updateUI(players));
* }).start();
*
* // Update existing player (background thread)
* new Thread(() -> {
* Player player = playerDao.getPlayerById(playerId);
* player.username = "New Name";
* playerDao.update(player);
* }).start();
* </pre>
* </p>
* <p>
* <strong>Database Table:</strong>
* This DAO operates on the "players" table, which is defined by the {@link Player}
* entity class with its {@code @Entity} annotation.
* </p>
* <p>
* <strong>Missing Operations:</strong>
* Note that this DAO does not currently include a DELETE operation. If player deletion
* is required, consider adding:
* <pre>
* @Delete
* void delete(Player player);
*
* // or
* @Query("DELETE FROM players WHERE id = :playerId")
* void deleteById(int playerId);
* </pre>

/**
* Inserts a new Player entity into the database.
* <p>
* This method persists a new player to the "players" table, adding them to the
* squad roster. Room will handle the actual SQL INSERT operation and automatically
* generate a primary key ID for the player if the ID field is configured with
* {@code @PrimaryKey(autoGenerate = true)}.
* </p>
* <p>
* <strong>Threading:</strong>
* This operation must be performed on a background thread. Attempting to call this
* on the main thread will result in an {@link IllegalStateException} (unless Room
* is explicitly configured to allow main thread queries, which is not recommended).
* </p>
* <p>
* <strong>Transaction Behavior:</strong>
* By default, Room wraps this operation in a database transaction. If the insert
* fails for any reason, the transaction will be rolled back, ensuring database
* consistency and atomicity.
* </p>
* <p>
* <strong>Conflict Strategy:</strong>
* The default conflict strategy is {@code OnConflictStrategy.ABORT}, which means
* if a conflict occurs (e.g., duplicate primary key), the insert will fail with
* an exception. This can be customized by adding a parameter to the {@code @Insert}
* annotation:
* <pre>
* @Insert(onConflict = OnConflictStrategy.REPLACE)
* void insert(Player player);
* </pre>
* </p>
* <p>
* <strong>Auto-Generated ID:</strong>
* 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).
* </p>
* <p>
* <strong>Usage Example:</strong>
* <pre>
* Player newPlayer = new Player("Alice", "/path/to/profile.jpg");
* newPlayer.careerAverage = 45.5;
*
* new Thread(() -> {
* try {
* playerDao.insert(newPlayer);
* // After insert, newPlayer.id will contain the auto-generated ID
* Log.d(TAG, "Inserted player with ID: " + newPlayer.id);
* } catch (Exception e) {
* Log.e(TAG, "Failed to insert player", e);
* }
* }).start();
* </pre>
* </p>
* <p>
* <strong>Validation:</strong>
* Ensure the player object contains all required fields before insertion:
* <ul>
* <li>Username should not be null or empty</li>
* <li>Profile picture URI can be null (default avatar will be used)</li>
* <li>Career average should be initialized (default to 0.0 if not set)</li>
* </ul>
* </p>
*
* @param player The Player object to be inserted into the database. Must not be null.
* Should contain valid username and optionally profile picture URI.
* @throws IllegalStateException if called on the main thread (Room's default behavior)
* @throws android.database.sqlite.SQLiteConstraintException if a constraint is violated
* @throws android.database.sqlite.SQLiteException if the database operation fails

* identifies the player to update using the primary key ID field in the provided
* Player object. All fields of the player will be updated to match the provided values.
* </p>
* <p>
* <strong>Primary Key Matching:</strong>
* Room uses the {@code @PrimaryKey} field (typically "id") to identify which
* database row to update. The player object must have a valid ID that exists in
* the database, or the update will have no effect.
* </p>
* <p>
* <strong>Threading:</strong>
* This operation must be performed on a background thread. Attempting to call this
* on the main thread will result in an {@link IllegalStateException} (unless Room
* is explicitly configured to allow main thread queries, which is not recommended).
* </p>
* <p>
* <strong>Transaction Behavior:</strong>
* By default, Room wraps this operation in a database transaction. If the update
* fails, the transaction will be rolled back, preventing partial updates and
* maintaining database consistency.
* </p>
* <p>
* <strong>Conflict Strategy:</strong>
* The default conflict strategy is {@code OnConflictStrategy.ABORT}. This can be
* customized if needed:

* </p>
* <p>
* <strong>Return Value:</strong>
* While this method returns void, the {@code @Update} annotation can be configured
* to return {@code int} indicating the number of rows updated (typically 1 for
* successful single-player updates, 0 if no matching player was found).
* </p>
* <p>
* <strong>Usage Example:</strong>
* <pre>
* // Typical update flow: query, modify, update
* new Thread(() -> {

* <p>
* <strong>SQL Query:</strong>

* }
* </pre>
* </p>

* } else {
* // Update RecyclerView adapter with player list
* playerAdapter.updatePlayers(allPlayers);

* </p>
* <p>
* <strong>Common Use Cases:</strong>
* <ul>
* <li>Displaying the squad roster in {@link com.aldo.apps.ochecompanion.MainMenuActivity}</li>
* <li>Populating player selection lists when creating a new match</li>
* <li>Showing all players in management/roster views</li>
* <li>Calculating squad-wide statistics</li>
* </ul>
* </p>
* <p>
* <strong>Alternative Implementations:</strong>
* Consider using LiveData for automatic UI updates:
* <pre>
* @Query("SELECT * FROM players ORDER BY username ASC")
* LiveData&lt;List&lt;Player&gt;&gt; getAllPlayersLive();
* </pre>
* Or Flow for Kotlin coroutines:
* <pre>
* @Query("SELECT * FROM players ORDER BY username ASC")

/**
* Represents a completed match or game leg in the Oche Companion application.
* <p>
* This entity class stores comprehensive information about a finished darts match,
* including the game mode played, completion timestamp, participant count, and
* detailed performance data for all players involved. The Match entity serves as
* the primary record for match history and statistics tracking.
* </p>
* <p>
* <strong>Room Database Entity:</strong>
* The {@code @Entity} annotation designates this class as a Room database table.
* Match records are stored in the "matches" table and can be queried using
* {@link com.aldo.apps.ochecompanion.database.dao.MatchDao} methods.
* </p>
* <p>
* <strong>Serializable Interface:</strong>
* This class implements {@link Serializable} to allow Match objects to be passed
* between Android components using Intent extras or Bundle arguments. This is
* useful when navigating to match detail screens or sharing match data between
* activities.
* </p>
* <p>
* <strong>Data Structure:</strong>
* Match data is stored with the following components:
* <ul>
* <li><strong>ID:</strong> Auto-generated primary key for database uniqueness</li>
* <li><strong>Timestamp:</strong> Unix epoch time marking match completion</li>
* <li><strong>Game Mode:</strong> The variant of darts played (e.g., "501", "301", "Cricket")</li>
* <li><strong>Player Count:</strong> Number of participants (supports 1v1 and group matches)</li>
* <li><strong>Participant Data:</strong> JSON-serialized performance metrics for all players</li>
* </ul>
* </p>
* <p>
* <strong>Participant Data Format:</strong>
* The {@code participantData} field contains a JSON array with detailed player performance:
* <pre>
* [
* {
* "id": 1,
* "username": "John Doe",
* "rank": 1,
* "score": 501,
* "average": 92.4,
* "highestCheckout": 170
* },
* {
* "id": 2,
* "username": "Jane Smith",
* "rank": 2,
* "score": 420,
* "average": 81.0,
* "highestCheckout": 120
* }
* ]
* </pre>
* This structure allows for flexible storage of various statistics while maintaining
* database normalization (avoiding separate tables for each match-player relationship).
* </p>
* <p>
* <strong>Game Mode Support:</strong>
* The application supports multiple darts game variants:
* <ul>
* <li><strong>501:</strong> Standard countdown game starting at 501 points</li>
* <li><strong>301:</strong> Faster countdown game starting at 301 points</li>
* <li><strong>Cricket:</strong> Number-based strategy game (15-20 and bulls)</li>
* <li><strong>Around the Clock:</strong> Sequential number hitting game</li>
* <li>Custom game modes can be added by extending the gameMode field</li>
* </ul>
* </p>
* <p>
* <strong>Match Types:</strong>
* The system supports different match configurations:
* <ul>
* <li><strong>1v1 Matches:</strong> Two-player head-to-head games (playerCount = 2)</li>
* <li><strong>Group Matches:</strong> Three or more players (playerCount >= 3)</li>
* <li><strong>Solo Practice:</strong> Single player practice sessions (playerCount = 1)</li>
* </ul>
* The UI adapts based on player count, showing specialized layouts for each match type.
* </p>
* <p>
* <strong>Usage Example:</strong>
* <pre>
* // 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&lt;Match&gt; 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);
* </pre>
* </p>
* <p>
* <strong>Database Relationships:</strong>
* While this entity doesn't use Room's {@code @Relation} annotations, it maintains
* logical relationships through the participant data:
* <ul>
* <li>Each match references multiple players via IDs in participantData JSON</li>
* <li>Player objects are stored separately in the "players" table</li>
* <li>The denormalized JSON approach optimizes read performance for match history</li>
* <li>Updates to player usernames won't automatically reflect in historical matches</li>
* </ul>
* </p>
* <p>
* <strong>Performance Considerations:</strong>
* <ul>
* <li>JSON parsing adds minimal overhead for typical match sizes (2-8 players)</li>
* <li>The timestamp field can be indexed for efficient chronological queries</li>
* <li>Consider paginating match history for users with hundreds of matches</li>
* <li>The Serializable interface has some overhead; consider Parcelable for better performance</li>
* </ul>
* </p>
* <p>
* <strong>Data Integrity:</strong>
* <ul>
* <li>The auto-generated ID ensures each match is uniquely identifiable</li>
* <li>Timestamp should always be positive and in milliseconds (Unix epoch)</li>
* <li>Player count should match the number of entries in participantData JSON</li>
* <li>Game mode string should be validated against supported game types</li>
* </ul>
* </p>
* <p>
* <strong>Future Enhancements:</strong>
* Consider adding these fields for expanded functionality:
* <ul>
* <li><strong>duration:</strong> Match duration in seconds for time tracking</li>
* <li><strong>location:</strong> Venue or location where match was played</li>
* <li><strong>notes:</strong> User-added comments or observations</li>
* <li><strong>isRanked:</strong> Boolean flag for competitive vs casual matches</li>
* <li><strong>tournamentId:</strong> Reference to tournament entity for organized play</li>
* </ul>

* <strong>Format:</strong>
* The timestamp is stored as a {@code long} value representing milliseconds.
* This is the standard Java/Android time format obtained via:
* <pre>
* long timestamp = System.currentTimeMillis();
* </pre>
* </p>
* <p>
* <strong>Example Values:</strong>
* <ul>
* <li>1737158400000L = January 17, 2025, 00:00:00 UTC</li>
* <li>1704067200000L = January 1, 2024, 00:00:00 UTC</li>
* </ul>
* </p>
* <p>
* <strong>Conversion Examples:</strong>
* <pre>
* // Convert to Date object
* Date matchDate = new Date(match.timestamp);
*
* // Format for display
* SimpleDateFormat sdf = new SimpleDateFormat("MMM dd, yyyy HH:mm", Locale.getDefault());
* String displayDate = sdf.format(matchDate);
*
* // Calculate time ago
* long hoursAgo = (System.currentTimeMillis() - match.timestamp) / (1000 * 60 * 60);
*
* // Use with Calendar
* Calendar calendar = Calendar.getInstance();
* calendar.setTimeInMillis(match.timestamp);
* int dayOfMonth = calendar.get(Calendar.DAY_OF_MONTH);
* </pre>
* </p>
* <p>
* <strong>Sorting:</strong>
* Matches can be ordered by timestamp to show most recent first:
* <pre>
* @Query("SELECT * FROM matches ORDER BY timestamp DESC LIMIT 10")
* List&lt;Match&gt; getRecentMatches();
* </pre>
* </p>
* <p>
* <strong>Validation:</strong>
* The timestamp should always be:
* <ul>
* <li>Positive (non-zero)</li>
* <li>Not in the future (unless testing)</li>
* <li>Reasonable (not before app creation date)</li>
* </ul>
* </p>
* <p>
* <strong>Timezone Considerations:</strong>
* While the timestamp is stored in UTC (Unix epoch), display formatting should
* consider the user's local timezone for proper date/time presentation.

/**
* The name or identifier of the game variant that was played in this match.
* <p>
* 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.
* </p>
* <p>
* <strong>Supported Game Modes:</strong>
* <ul>
* <li><strong>"501":</strong> The classic countdown game starting at 501 points.
* Players subtract their scores and must finish exactly on zero with a double.</li>
* <li><strong>"301":</strong> A faster variant starting at 301 points, following
* the same rules as 501 but requiring quicker gameplay.</li>
* <li><strong>"Cricket":</strong> Strategic game focusing on numbers 15-20 and
* the bullseye. Players must "close" numbers by hitting them three times.</li>
* <li><strong>"Around the Clock":</strong> Sequential game where players must
* hit numbers 1-20 in order, then finish with a bullseye.</li>
* <li><strong>"Killer":</strong> Multiplayer elimination game where each player
* has a designated number and tries to eliminate opponents.</li>
* </ul>
* </p>
* <p>
* <strong>String Format:</strong>
* Game mode strings should be:
* <ul>
* <li>Non-null and non-empty</li>
* <li>Consistent in naming (avoid "501", "Five-Oh-One", "501 Game" variations)</li>
* <li>Preferably using predefined constants to avoid typos</li>
* </ul>
* </p>
* <p>
* <strong>Recommended Usage:</strong>
* <pre>
* // Define constants for game modes
* public static final String GAME_MODE_501 = "501";
* public static final String GAME_MODE_301 = "301";
* public static final String GAME_MODE_CRICKET = "Cricket";
*
* // Use constants when creating matches
* Match match = new Match(
* System.currentTimeMillis(),
* GAME_MODE_501, // Instead of hardcoded "501"
* 2,
* participantJson
* );
* </pre>
* </p>
* <p>
* <strong>UI Adaptation:</strong>
* The game mode affects how matches are displayed:
* <pre>
* switch (match.gameMode) {
* case "501":
* case "301":
* // Show countdown score display
* // Highlight checkout attempts
* break;
* case "Cricket":
* // Show cricket scoreboard with marks
* // Display closed numbers
* break;
* case "Around the Clock":
* // Show sequential progress indicator
* break;
* }
* </pre>
* </p>
* <p>
* <strong>Filtering and Statistics:</strong>
* Game mode enables targeted queries and statistics:
* <pre>
* // Get all 501 matches
* @Query("SELECT * FROM matches WHERE gameMode = '501'")
* List&lt;Match&gt; get501Matches();
*
* // Calculate average score by game mode
* Map&lt;String, Double&gt; averagesByMode = calculateAveragesByGameMode();
* </pre>
* </p>
* <p>
* <strong>Extensibility:</strong>
* New game modes can be added without schema changes:
* <ul>
* <li>Simply use a new string identifier</li>
* <li>Implement game-specific logic in the game engine</li>
* <li>Update UI to handle the new mode</li>
* <li>Ensure participant data JSON includes mode-specific metrics</li>
* </ul>
* </p>
* <p>
* <strong>Validation:</strong>
* Consider validating game mode before inserting matches:
* <pre>
* private static final Set&lt;String&gt; VALID_GAME_MODES = new HashSet&lt;&gt;(
* Arrays.asList("501", "301", "Cricket", "Around the Clock", "Killer")
* );
*
* if (!VALID_GAME_MODES.contains(gameMode)) {
* throw new IllegalArgumentException("Invalid game mode: " + gameMode);
* }
* </pre>
* </p>

/**
* The total number of players who participated in this match.
* <p>
* This field indicates how many individuals competed in the match, which
* determines the match type and affects how the UI displays the results.
* The player count must match the number of player entries in the
* {@link #participantData} JSON array.
* </p>
* <p>
* <strong>Valid Range:</strong>
* <ul>
* <li><strong>1:</strong> Solo practice session (single player)</li>
* <li><strong>2:</strong> Head-to-head match (1v1 duel)</li>
* <li><strong>3+:</strong> Group match or multiplayer game</li>
* </ul>
* Typically ranges from 1 to 8 players, though the system can support more.
* </p>
* <p>
* <strong>Match Type Determination:</strong>
* The player count affects UI rendering and game logic:
* <pre>
* if (match.playerCount == 1) {
* // Show solo practice UI
* // Display personal stats only
* // No ranking or comparison
* } else if (match.playerCount == 2) {
* // Show 1v1 layout (MatchRecapView.setup1v1State)
* // Display winner/loser clearly
* // Show head-to-head comparison
* } else {
* // Show group match layout (MatchRecapView.setupGroupState)
* // Display ranked list of all players
* // Show leaderboard-style results
* }
* </pre>
* </p>
* <p>
* <strong>Data Consistency:</strong>
* The player count should always match the participant data:
* <pre>
* // Validate consistency
* JSONArray participants = new JSONArray(match.participantData);
* if (participants.length() != match.playerCount) {
* Log.w(TAG, "Mismatch: playerCount=" + match.playerCount +
* " but participantData has " + participants.length() + " entries");
* }
* </pre>
* </p>
* <p>
* <strong>Performance Implications:</strong>
* <ul>
* <li>Higher player counts require more complex UI layouts</li>
* <li>Sorting and ranking algorithms scale with player count</li>
* <li>JSON parsing time increases with more participants</li>
* <li>Consider pagination for matches with many players</li>
* </ul>
* </p>
* <p>
* <strong>Usage in Queries:</strong>
* <pre>
* // Get all 1v1 matches
* @Query("SELECT * FROM matches WHERE playerCount = 2")
* List&lt;Match&gt; getDuelMatches();
*
* // Get group matches only
* @Query("SELECT * FROM matches WHERE playerCount >= 3")
* List&lt;Match&gt; getGroupMatches();
* </pre>
* </p>
* <p>
* <strong>Statistical Analysis:</strong>
* Player count enables performance tracking by match type:
* <pre>
* // Calculate win rate in 1v1 matches
* double winRate1v1 = calculateWinRate(playerId, 2);
*
* // Calculate average placement in group matches
* double avgPlacement = calculateAveragePlacement(playerId, 3);
* </pre>
* </p>
* <p>
* <strong>Validation:</strong>
* Always validate player count before creating a match:
* <pre>
* if (playerCount < 1) {
* throw new IllegalArgumentException("playerCount must be at least 1");
* }
* if (playerCount > MAX_PLAYERS) {
* throw new IllegalArgumentException("Too many players: " + playerCount);

* Using JSON serialization allows flexible storage of different metrics without
* requiring separate database tables for each match-player relationship.
* </p>
* <p>
* <strong>JSON Structure:</strong>
* The participant data is stored as a JSON array of player objects:
* <pre>
* [
* {
* "id": 1, // Player database ID
* "username": "John Doe", // Player display name
* "rank": 1, // Final placement (1 = winner)
* "score": 501, // Final score or points
* "average": 92.4, // Three-dart average
* "highestCheckout": 170, // Largest finish
* "dartsThrown": 45, // Total darts thrown
* "profilePictureUri": "/path/to/pic.jpg" // Profile image
* },
* {
* "id": 2,

* "highestCheckout": 120,
* "dartsThrown": 51,
* "profilePictureUri": "/path/to/pic2.jpg"
* }
* ]
* </pre>
* </p>
* <p>
* <strong>Required Fields:</strong>
* Each participant object must contain:
* <ul>
* <li><strong>id:</strong> Player database ID for linking to Player entity</li>
* <li><strong>username:</strong> Display name at time of match (snapshot)</li>
* <li><strong>rank:</strong> Final placement (1 = winner, 2 = second, etc.)</li>
* </ul>
* </p>
* <p>
* <strong>Optional Fields:</strong>
* Additional metrics that may be included:
* <ul>
* <li><strong>score:</strong> Final score or remaining points</li>
* <li><strong>average:</strong> Three-dart average throughout the match</li>
* <li><strong>highestCheckout:</strong> Largest checkout/finish</li>
* <li><strong>dartsThrown:</strong> Total number of darts thrown</li>
* <li><strong>profilePictureUri:</strong> Profile image path (snapshot)</li>
* <li><strong>180s:</strong> Number of maximum scores (180) hit</li>
* <li><strong>checkoutPercentage:</strong> Success rate on finish attempts</li>
* </ul>
* </p>
* <p>
* <strong>Parsing Example:</strong>
* <pre>
* try {
* JSONArray participants = new JSONArray(match.participantData);
*
* for (int i = 0; i &lt; participants.length(); i++) {
* JSONObject player = participants.getJSONObject(i);
*
* int playerId = player.getInt("id");
* String username = player.getString("username");
* int rank = player.getInt("rank");
* double average = player.optDouble("average", 0.0);
*
* // Use the data to populate UI
* displayPlayerResult(username, rank, average);
* }
* } catch (JSONException e) {
* Log.e(TAG, "Failed to parse participant data", e);
* }
* </pre>
* </p>
* <p>
* <strong>Building Participant Data:</strong>
* <pre>
* // Create JSON array when match ends
* JSONArray participants = new JSONArray();
*
* for (Player player : matchPlayers) {
* JSONObject playerData = new JSONObject();
* playerData.put("id", player.id);
* playerData.put("username", player.username);
* playerData.put("rank", player.finalRank);
* playerData.put("score", player.finalScore);
* playerData.put("average", player.calculateAverage());
* playerData.put("highestCheckout", player.highestCheckout);
* playerData.put("profilePictureUri", player.profilePictureUri);
*
* participants.put(playerData);
* }
*
* String participantDataString = participants.toString();
* Match match = new Match(timestamp, gameMode, playerCount, participantDataString);
* </pre>
* </p>
* <p>
* <strong>Why JSON Instead of Relations:</strong>
* <ul>
* <li><strong>Performance:</strong> Single query retrieves complete match data</li>
* <li><strong>Historical Accuracy:</strong> Captures player data as it was at match time</li>
* <li><strong>Flexibility:</strong> Can store game-specific metrics without schema changes</li>
* <li><strong>Simplicity:</strong> Avoids complex join queries and relationship management</li>
* <li><strong>Immutability:</strong> Match data remains unchanged if player profiles are updated</li>
* </ul>
* </p>
* <p>
* <strong>Data Integrity:</strong>
* <ul>
* <li>Array length should match {@link #playerCount}</li>
* <li>Ranks should be sequential (1, 2, 3, ...) without gaps</li>
* <li>Player IDs should reference valid players (though not enforced by foreign key)</li>
* <li>JSON must be well-formed and parseable</li>
* </ul>
* </p>
* <p>
* <strong>Snapshot Advantage:</strong>
* 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.
* </p>
* <p>
* <strong>Sorting Participants:</strong>
* Usually pre-sorted by rank before serialization, but can be sorted after parsing:
* <pre>
* // Sort by rank after parsing
* Collections.sort(playerList, (p1, p2) ->
* Integer.compare(p1.rank, p2.rank));
* </pre>
* </p>
* <p>
* <strong>Null Handling:</strong>
* 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.

* no need to set it manually. All parameters are required to create a valid match.
* </p>
* <p>
* <strong>Constructor Parameters:</strong>
* Each parameter serves a specific purpose in defining the match:
* <ul>
* <li><strong>timestamp:</strong> Records when the match was completed for chronological ordering</li>
* <li><strong>gameMode:</strong> Identifies which darts variant was played</li>
* <li><strong>playerCount:</strong> Specifies how many players participated</li>

* }).start();
* </pre>
* </p>
* <p>
* <strong>Parameter Validation:</strong>
* While the constructor doesn't enforce validation, consider checking parameters
* before construction:
* <pre>
* // Validate before creating match
* if (timestamp <= 0) {
* throw new IllegalArgumentException("Invalid timestamp");
* }
* if (gameMode == null || gameMode.isEmpty()) {
* throw new IllegalArgumentException("Game mode is required");

* throw new IllegalArgumentException("Invalid JSON format", e);
* }
*
* // Create match after validation
* Match match = new Match(timestamp, gameMode, playerCount, participantData);
* </pre>
* </p>
* <p>
* <strong>Field Initialization:</strong>
* The constructor initializes all fields except {@code id}:
* <ul>
* <li><strong>id:</strong> Remains 0 (default) until Room assigns auto-generated value</li>
* <li><strong>timestamp:</strong> Set to the provided value (milliseconds since epoch)</li>
* <li><strong>gameMode:</strong> Set to the provided game identifier string</li>
* <li><strong>playerCount:</strong> Set to the provided player count</li>
* <li><strong>participantData:</strong> Set to the provided JSON string</li>
* </ul>
* </p>
* <p>
* <strong>Database Insertion:</strong>
* After construction, insert the match using the DAO:
* <pre>
* // 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();
* });
* });
* </pre>
* </p>
* <p>
* <strong>Immutability Consideration:</strong>
* Once created and inserted, match data should generally be treated as immutable
* (historical record). If corrections are needed, consider whether to:
* <ul>
* <li>Update the existing match (rare, only for data corrections)</li>
* <li>Delete and recreate (for significant errors)</li>
* <li>Leave as-is and add a note field (preserves history)</li>
* </ul>
* </p>
* <p>
* <strong>Thread Safety:</strong>
* The constructor itself is thread-safe, but database insertion must occur on
* a background thread due to Room's main thread restrictions.
* </p>
*
* @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",

/**
* Model class representing a darts match with multiple participants.
* <p>
* This class serves as a data container for match information in the Oche Companion app,
* maintaining a collection of players participating in a single darts game session.
* It provides convenient methods for accessing player information by position and
* retrieving match statistics.
* </p>
* <p>
* <strong>Key Features:</strong>
* <ul>
* <li>Support for matches with any number of players (1v1, group matches, etc.)</li>
* <li>Position-based player access for ordered operations</li>
* <li>Convenient retrieval of player names and career averages</li>
* <li>Flexible construction with varargs or default empty initialization</li>
* </ul>
* </p>
* <p>
* <strong>Match Types:</strong>
* This class supports different match configurations:
* <ul>
* <li><strong>1v1 Match:</strong> Exactly 2 players for head-to-head competition</li>
* <li><strong>Group Match:</strong> 3 or more players for multi-player games</li>
* <li><strong>Solo Practice:</strong> Single player for practice sessions (if supported)</li>
* </ul>
* </p>
* <p>
* <strong>Player Ordering:</strong>
* Players are stored in the order they are added. This ordering is significant for:
* <ul>
* <li>Displaying players in consistent positions (left/right, top/bottom)</li>
* <li>Turn order during gameplay</li>
* <li>Result display and leaderboards</li>
* </ul>
* </p>
* <p>
* <strong>Usage Examples:</strong>
* <pre>
* // Create a 1v1 match
* Match match = new Match(player1, player2);
*
* // Create a group match
* Match groupMatch = new Match(player1, player2, player3, player4);
*
* // Create an empty match and add players later
* Match emptyMatch = new Match();
* // (Note: No public add method currently, consider adding if needed)
* </pre>
* </p>
* <p>
* <strong>Design Notes:</strong>
* <ul>
* <li>The class is mutable in that it stores player references, but doesn't provide
* methods to add/remove players after construction</li>
* <li>Player data (names, averages) is accessed directly from Player objects</li>
* <li>Currently focused on displaying match information rather than tracking live gameplay</li>
* </ul>

* which establishes their position indices for future queries.
* </p>
* <p>
* <strong>Varargs Convenience:</strong>
* The varargs parameter allows flexible calling patterns:
* <pre>
* // 1v1 match
* Match match1 = new Match(player1, player2);
*
* // Group match
* Match match2 = new Match(player1, player2, player3, player4);
*

* Match match3 = new Match(player1);
*
* // From array
* Player[] playerArray = {player1, player2, player3};
* Match match4 = new Match(playerArray);
* </pre>
* </p>
* <p>
* <strong>Player Ordering:</strong>
* Players are stored in the exact order they are passed. For example:
* <ul>
* <li>First player: position 0</li>
* <li>Second player: position 1</li>
* <li>And so on...</li>
* </ul>
* This ordering is important for methods like {@link #getPlayerNameByPosition(int)}.
* </p>
* <p>
* <strong>Logging:</strong>
* Each player addition is logged at debug level for troubleshooting and verification.
* </p>
* <p>
* <strong>Null Safety:</strong>
* This constructor does not explicitly check for null players. Callers should ensure
* all provided Player objects are non-null to avoid NullPointerExceptions in
* subsequent operations.
* </p>
*

* Custom view that provides a visual cropping guide overlay for image selection.
* <p>
* This view is designed for use in the Oche Companion app's image cropping interface,
* specifically within the {@link com.aldo.apps.ochecompanion.AddPlayerActivity}.
* It creates a semi-transparent dark overlay across the entire view with a transparent
* square "window" in the center, allowing users to see exactly which portion of their
* image will be captured as their profile picture.
* </p>
* <p>
* <strong>Visual Design:</strong>
* <ul>
* <li>Dark semi-transparent mask (85% opacity Midnight Black) covers the entire view</li>
* <li>Transparent square cutout in the center shows the crop area</li>
* <li>Crop box is 80% of the view's width, maintaining a square aspect ratio</li>
* <li>Automatically centers the crop box within the view</li>
* </ul>
* </p>
* <p>
* <strong>Technical Implementation:</strong>
* The overlay uses a {@link Path} with clockwise and counter-clockwise rectangles to create
* a "hole punch" effect. 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.
* </p>
* <p>
* <strong>Usage:</strong>
* This view is typically overlaid on top of an {@link android.widget.ImageView} in crop mode.
* The parent activity can retrieve the crop rectangle coordinates via {@link #getCropRect()}
* to perform the actual pixel-level cropping calculations.

* Custom hero-style button component for initiating quick match sessions.
* <p>
* This prominent interactive view is designed to be the primary call-to-action on the
* dashboard, providing users with a fast and intuitive way to start a new match with
* pre-configured settings. The component features a distinctive visual design with:
* <ul>
* <li>A large, bold primary label (e.g., "QUICK START")</li>
* <li>A secondary descriptive subtext showing game mode and rules</li>
* <li>Hero-style prominent appearance matching dashboard mockups</li>
* </ul>
* </p>
* <p>
* <strong>Design Philosophy:</strong>
* This button follows the "hero component" design pattern, where a single large,
* visually distinctive element serves as the primary action on a screen. This makes
* it immediately obvious to users how to start playing without navigating through
* multiple menus or configuration screens.
* </p>
* <p>
* <strong>Key Features:</strong>
* <ul>
* <li>Dual-text hierarchy with main title and descriptive subtitle</li>
* <li>Automatic text uppercasing for visual consistency</li>
* <li>Convenience method for updating game context (mode and rules)</li>
* <li>Built-in clickable and focusable configuration for accessibility</li>
* <li>Efficient merge-tag layout inflation pattern</li>
* </ul>
* </p>
* <p>
* <strong>Usage Example:</strong>
* <pre>
* QuickStartButton button = findViewById(R.id.quickStartButton);
* button.setMainText("Quick Start");
* button.updateContext("501", "Double Out");
* button.setOnClickListener(v -> startMatch());

/**
* Convenience method to update the subtitle based on game mode and rules.
* <p>
* 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.
* </p>
* <p>
* <strong>Formatting Behavior:</strong>
* <ul>
* <li>If rules are provided: Displays "[MODE] - [RULES]" (e.g., "501 - DOUBLE OUT")</li>
* <li>If rules are empty/null: Displays only "[MODE]" (e.g., "501")</li>
* </ul>
* </p>
* <p>
* <strong>Example Usage:</strong>
* <pre>
* // 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"
* </pre>
* </p>
* <p>
* <strong>Advantages over setSubText:</strong>
* <ul>
* <li>Provides consistent formatting across the app</li>
* <li>Handles null/empty rules gracefully</li>
* <li>Reduces code duplication in calling code</li>
* <li>Makes intent clearer (semantic method name)</li>
* </ul>
* </p>
* <p>
* <strong>Implementation Details:</strong>
* The method uses {@link StringBuilder} for efficient string concatenation,
* especially useful if called frequently. It checks if rules are empty using
* {@link TextUtils#isEmpty(CharSequence)} which handles both null and empty strings.
* </p>
*
* @param mode The game mode identifier (e.g., "501", "301", "Cricket").
* Should not be null or empty as this is the primary information.
* @param rules Optional summary of game rules (e.g., "Double Out", "Single In/Double Out").
* Can be null or empty, in which case only the mode is displayed.
* @see #setSubText(String)
* @see TextUtils#isEmpty(CharSequence)
* @see StringBuilder
*/

# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.
