java - Android capturing volume up/down key presses in broadcast receiver? -

i'm trying create application user can override default behaviour of volume up/down buttons (as screen on/off button - possible?). anyways, using code along lines of next can this:

@override public boolean onkeydown(int keycode, keyevent event) { super.onkeyup(keycode, event); if ((keycode == keyevent.keycode_volume_up)) { //this can stuff homecoming true; //because handled event } homecoming false; //otherwise scheme can handle

}

but possible when application not open, hence why i'd set broadcast receiver or maybe stick in service create possible.
