Description

  • Version: 1.6.3 (Upgraded)

  • Device: OnePlus 3T (was happening on OnePlus One as well)

  • OS version: Android 7.0 (was happening on previous versions as well)

  • Description: After connecting phone to bluetooth device (tried with headphones and bluetooth in a car), it's not possible to control the player. Simply any playback controls (play/pause, next/prev, is not responding). But after you play a song from widget/app, then it's possible to control it via bluetooth. If you first play a song and later connect to bluetooth, it's possible to control it.

  • Outcome: I assume that the reason it's happening is, that when you connect bluetooth device and app was not running, the broadcast receiver for bluetooth controls is not registered, therefore it can't control the app.

Research direction
The issue suggests that the Bluetooth broadcast receiver is not registered when the app is not running. Investigate the Android manifest and the main activity's lifecycle to see where the Bluetooth device connection action (android.bluetooth.device.action.ACL CONNECTED) is handled. Look for where the MediaSession or playback controls are set up. The likely fix is to ensure the broadcast receiver is registered in the Application class or when the service starts, or to start a foreground service that registers the receiver. Check the current implementation in the BluetoothReceiver.java or similar file.
