I’ve applied the changes from Chapter 5 of the book and everything builds correctly and runs. But, when I try to start a game, the following exception is being thrown:

android.database.sqlite.SQLiteConstraintException: UNIQUE constraint failed: game_statuses.gameId, game_statuses.playerId (code 1555 SQLITE_CONSTRAINT_PRIMARYKEY)

Any suggestion on what to check in the project code?
