Background AudioService Stops After Receiving a Phone Call

[drahmedgabr]

Which API doesn't behave as documented, and how does it misbehave?

Android API: Specifically, the AudioManager or AudioService API in Android might be involved here, especially if the documentation suggests that background audio should resume after an interruption like a phone call but it fails to do so.

Misbehavior: After a phone call, the background audio service resumes for approximately 5 minutes and then unexpectedly stops. Additionally, when the audio resumes after the call and the app is reopened from the notification bar, closing the app causes the audio service to be destroyed. This behavior is inconsistent with the expected functionality where the audio service should continue running in the background.

5. Wait approximately 5 minutes – the audio service will stop unexpectedly.
   Or
6. Reopen the app from the notification.
7. Close the app again – the audio service stops immediately.
