More version details

No response

Devices that reproduce the issue

Amazon Fire HD 10 (13th Gen) (OS 11)
Alcatel 1 (OS 11)

Devices that do not reproduce the issue

Pixel 6a (OS 15)
Samsung Flip 5 (OS 15)

Reproducible in the demo app?

Yes

Reproduction steps

To reproduce with the demo app requires a small modification.

This would need added to the DemoPlaybackService

@OptIn(UnstableApi::class)
override fun onTaskRemoved(rootIntent: Intent?) {
  super.onTaskRemoved(rootIntent)
  pauseAllPlayersAndStopSelf()
}

Then:

1. Open app
2. Play anything
3. Close app
4. Resume playback from the notification player
5. Observe crash in logcat

---

In my app the notification doesn't usually stick around after close(though sometimes it will on different devices), however the same crash could be triggered by headphone media control & adb keyevent(adb shell input keyevent 85)

Expected result

Media playback and service stops.

Actual result

Media playback stops but service does not or is recreated(?)

Notification player still persists with broken controls, need to launch app and play something to fix.

I assume you can't stop your service because there still is an connected controller bound to your service. @marcbaechinger is probably able to confirm that or provide a better explanation.

Still in the demo-session app, by logging the mediaLibrarySession.connectedControllers on each onGetSession and onTaskRemoved I get:

onGetSession: androidx.media3.session.MediaLibraryService$MediaLibrarySession@25a13e [] <-- Initial open
onGetSession: androidx.media3.session.MediaLibraryService$MediaLibrarySession@25a13e [ControllerInfo {pkg=androidx.media3.demo.session, uid=10168}, ControllerInfo {pkg=androidx.media3.demo.session, uid=10168}] <-- Open Artist folder
onGetSession: androidx.media3.session.MediaLibraryService$MediaLibrarySession@25a13e [ControllerInfo {pkg=androidx.media3.demo.session, uid=10168}, ControllerInfo {pkg=androidx.media3.demo.session, uid=10168}] <-- Play track
onGetSession: androidx.media3.session.MediaLibraryService$MediaLibrarySession@25a13e [ControllerInfo {pkg=androidx.media3.demo.session, uid=10168}, ControllerInfo {pkg=androidx.media3.demo.session, uid=10168}]
onTaskRemoved: androidx.media3.session.MediaLibraryService$MediaLibrarySession@25a13e [ControllerInfo {pkg=androidx.media3.demo.session, uid=10168}, ControllerInfo {pkg=com.android.systemui, uid=10113}]  <-- Close app
onGetSession: androidx.media3.session.MediaLibraryService$MediaLibrarySession@4a13899 [] <-- Immediately after close
onGetSession: androidx.media3.session.MediaLibraryService$MediaLibrarySession@e5d8e2f [] <-- Play from notification a few seconds later and crashes in background

So it's spinning up a new session immediately after close but not enough time/interaction to see what controllers are connected. Then another session again on trying to play from the notification but crashes before any controller info can be captured.

On an emulator or Pixel device I see nothing after the onTaskRemoved.
