Power key event in android?

Question

I want to listen to power key event. How can I do that?

Currently the code I am using is this:

    @Override
public boolean onKeyDown(int keyCode, Ke         


        

Answer 1

You should check in your override function onKeyDown

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

and the same with onKeyLongPress if you using

Another way you would like to handle screen off, you can register BroadcastReceiver with action Intent.ACTION_SCREEN_OFF
