AudioService is currently notified of wired headset and A2DP sink connection states via broadcast intents from WiredAccessoryObserver and BluetoothA2dpService. This is a problem as there is no guaranty that AudioService can take actions upon the change before other apps are notified. For instance, the Play On feature requires the UI to be refreshed when a device is inserted/removed and we must guaranty that the UI component can read new A2DP enable state from AudioManager after it receives a device connection state change intent. - Added hidden methods to AudioManager so that WiredAccessoryObserver and BluetoothA2dpService can notify AudioService of device connection directly. - The wired accessories connection intents are now sent by AudioService. - The A2DP state change intent is delayed by BluetoothA2DPService when ACTION_AUDIO_BECOMING_NOISY is sent by AudioService - ACTION_AUDIO_BECOMING_NOISY intent is not sent when disconnecting A2DP while a wired headset is present and vice versa.
