Background Music

The app includes looped background music functionality that can be toggled by the user from the Settings screen.

How It Works

The BackgroundMusicPlayer singleton in utility/settings/BackgroundMusicPlayer.kt manages all music playback operations using Android's MediaPlayer.

Lifecycle:

  • Initialization:

    • BackgroundMusicPlayer.initialize(context) is called once in SettingFragment.onViewCreated() to set up the MediaPlayer.
    • It loads the R.raw.drums_sound audio and prepares it to loop.

  • Start/Pause:

    • Users can start or pause the music (via a toggle switch, currently commented out).
    • startMusic() plays the music if not already playing.
    • pauseMusic() stops it temporarily.

  • Stop:

    • stopMusic() is used to permanently stop and release the media player.

  • Volume:

    • Default volume is 0.5 (range: 0.0 - 1.0).
    • Can be increased or decreased using UI buttons (currently commented out).
    • Changes are applied live and persisted in SharedPreferences.

Accessibility

The volume level is announced when adjusted to improve accessibility for visually impaired users.
