I've noticed a weird behaviour with music lock screen appearance and I'm curious to learn if it is a bug or something intended.
An app can show music lock screen control if it has the Audio focus and has registered a RemoteControlClient instance with AudioManager.registerRemoteControlClient(). Now consider the following sequence 1. Launch Google Music. It shows the lock screen controls if you display the lock screen. fine 2. Launch another music player like PowerAMP. Make it plays something. It takes the audio focus and shows its lock screen controls if you display the lock screen. fine 3. Go back to Google Music. PowerAMP is still playing music (because Google Music had no reason to take the focus) but the lock screen controls for it are not showing anymore (no lock screen controls at all) Is that normal ? Expected behaviour would be that PowerAMP lock screen controls still show until Google Music take the audio focus but it seems that any app having a RemoteControlClient registered cancel any other RemoteControlClient from a playing background app. Note that the exact same thing happen as described above if you swap Google Music and PowerAMP in the text. I'm asking that question because my app which manage lock screen controls behaves like above, removing the lock screen controls of any background playing app, when my app go into the foreground (without requesting audio focus). PS: the documentation of RemoteControlClient doesn't mention at any point the relation with the audio focus, which is really a glaring omission. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
