Merge "Fix bug 2599698 Music paused by itself The NotificationPlayer sets an OnCompletionListener on the MediaPlayer it's using to play the notification. NotificationPlayer relies on the completion event to abandon audio focus.  The player was started before the listener was set. The theory about the bug is that the player finished playing before the listener was called. Therefore the audio focus was never abandonned, and the music didn't resume." into froyo
