On a rooted device, you can use the Xposed framework to hook yourself into PhoneWindowManager. A good example is the Xposed Torch Module. Just decompile it and see how they do things.

You can detect this by polling AudioManager for current volume, it's not nice solution, but i don't know better.

private Handler handler;
public int volume;

private Runnable volumeUpdater = new Runnable() {
    private int updatesInterval = 100;      
    @Override
    public void run() {
        if(volume != audioManager.getStreamVolume(AudioManager.STREAM_MUSIC)){
            //volume changed put logic here
        }
        handler.postDelayed(volumeUpdater, updatesInterval);
    }
};

Try to use following code - 

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ((keyCode == KeyEvent.KEYCODE_VOLUME_DOWN)){
        //Do something
    }
    return true;
}

for background - any way to detect volume key presses or volume changes with android service?
