Immediate value you can get if you use AudioManager

AudioManager mAudioManager = Context.getSystemService(Context.AUDIO_SERVICE);
mAudioManager.getStreamVolume(STREAM_MUSIC);

The only function that gives you opportunity to register broadcast receiver is

mAudioManager.registerMediaButtonEventReceiver(audioBroadcastReceiver);

where audioBroadcastReceiver extends BroadcastReceiver and must be declared in the application manifest.

Not sure if this is exactly what you were looking for.

I don't get any events from the volume rocker on the phone, only from my headset. Should it be possible to get from the volume rocker as well? – tidbeck Jan 05 '12 at 11:13
Definitely. But first unplug your headset, to see if it works without it. Not sure if they are sent if you have headset and try to change volume using phone rocker. – Zelimir Jan 05 '12 at 12:14
