audio - Is there a listener to listen for changes in the volume in android?

Question

Is it possible to register a listener to listen for changes in the volume level of the music stream in Android?

I'm displaying the actual volume in a SeekBar and I would like to change the seekbar if the user changes the volume with the hardware volume keys. At the moment the correct volume is displayed until the user changes the volume with hardware keys.

This is not a perfect answer but a hack:

android.media.VOLUME_CHANGED_ACTION

I found above action in native logs while changing volume via hard volume key.

01-25 16:11:24.015: DEBUG/VolumePanel(189): onVolumeChanged(streamType: 2, flags: 4)
01-25 16:11:24.015: DEBUG/BluetoothA2dpService(189): Received intent with action: android.media.VOLUME_CHANGED_ACTION

so go ahead and register BroadcastReceiver with action "android.media.VOLUME_CHANGED_ACTION" if you don't have any other solution.

Other way of doing is; Taking over the volume key on Android .
