Here's video of the bug occurring, perhaps an important reproduction step is you have to navigate back to the home screen before going to the recent apps list, otherwise it doesn't seem to occur

Yeah, true. I can repro this. Took a while to make it repro but I was able to see that twice now. Thanks for reporting. We look into this.

[marcbaechinger]

This is a bug in Android 14. We have reported this internally and a fix is on it's way. There is nothing Media3 as a library or an app could do about it.

It has been fixed to the security patch version of 2024-02-05, Android14, Pixel6

It's my mistake. sorry.
This bug still exists.

[marcbaechinger]

Thanks for the heads up. Can you give us the build number with which you have verified this has been fixed and how you tried to repro?

When I test with UQ1A.240205.004 I still see the problem I'm afraid.

@svenoaks @marcbaechinger I'm facing this issue on Android 13 as well. The work around that I have implemented as @marcbaechinger described in one of the comments is to release the player and session before calling stopSelf in onTaskRemoved. I just wanted to confirm whether this issue is only occurring when player is paused ? as when player is playing and I remove app from recents, it works fine.

I think these are two different issues.

On Android 14 and with the repro steps from above, onTaskRemoved isn't called at all.

Pausing the player to repro this issue is required, because that is how the demo app is implemented. Without pausing, playback would continue in the background when dismissing the app from recents which is working as intended.

Generally, to stop the service the service must not run in the foreground (hence the player needs to be paused) and no controller/browser must be bound to the service (options: all controller disconnected already or the session is released). If either of these conditions are violated, calling stopSelf is a no-op.
