Answer 1

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ((keyCode == KeyEvent.KEYCODE_VOLUME_DOWN)) {

        return true;
    } else if ((keyCode == KeyEvent.KEYCODE_VOLUME_UP)) {
        // ... your code
        return true;
    } else
        return super.onKeyDown(keyCode, event);
}
