AudioService maintains a stack of registered media button event receivers. This change modifies the broadcasters of ACTION_MEDIA_BUTTON intents let AudioService directly handle the corresponding key event instead of trapping the intent sent by PhoneWindowManager, KeyguardViewBase and PhoneFallbackEventHandler. Because the key event may be sent through a PendingIntent, AudioService now also implements the OnFinished interface to be notified when the event was consumed so it can release the wake lock held if it was held when the key event needed to be sent (see where PassHeadsetKey was instanciated in PhoneWindowManager).
