Answer 1

this is an key down event of power you can get some idea from this just try on this you'll get some idea... i didnt try such an act but i found this in power manager.

public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (event.getKeyCode() == KeyEvent.KEYCODE_POWER) {
        // do what you want with the power button
        return true;
    }
    return super.onKeyDown(keyCode, event);
}
