The actual replacement for everything audio_service plugin wrapped.
Media3 owns the foreground-service lifecycle, MediaSession token,
notification card, lock-screen surface, Bluetooth/AVRCP routing,
Pixel Watch tile, and Android Auto adapter natively — no plugin
layer between us and the platform.
Service shape (~25 LOC):
- @AndroidEntryPoint MediaSessionService
- @Inject PlayerFactory builds ExoPlayer in onCreate
- onGetSession returns the live MediaSession to any binding
controller (system UI, Wear OS companion, MediaController3 clients)
- onTaskRemoved keeps playing while audio is active (standard
media-app behavior); otherwise stopSelf so notification clears
- onDestroy releases session + player
Compare with flutter_client/lib/player/audio_handler.dart's 1000+ LOC
across MinstrelAudioHandler + the soft-teardown / stall-watchdog /
recovery machinery. Media3 owns most of that natively; we'll get to
the small portions we still need (queue management, position
reporting facade) in 6.3.
Manifest registration: foregroundServiceType="mediaPlayback" +
MediaSessionService intent-filter. MediaButtonReceiver is registered
by the Media3 library; no manual receiver class needed (Flutter's
manifest had to declare audio_service's receiver explicitly).
