I don't know whether I got you right: do you mean whether reacting to key events of a physical keyboard? If so, you should be able to overwrite dispatchKeyEvent of your keyboard activity.

@Override
public boolean dispatchKeyEvent(KeyEvent event) {
    if (event.getAction() == KeyEvent.ACTION_UP) {
        switch (event.getKeyCode()) {
            case KeyEvent.KEYCODE_2:
            case KeyEvent.KEYCODE_NUMPAD_2:
                handleInput("2");
                return true;
        }
    }

    return super.dispatchKeyEvent(event);
}

Your code seems to be working fine.....it plays the music check your xml file and cross-check if you are reffering the correct id to each button and check your device volume sound incase its muted

and also post your aactivity.xml file if still didnt fix
