Detect power button long press

Question

I\'ve been reading some posts here on Stackoverflow, and I didn\'t find a good solution, I\'m wondering if it\'s possible to detect when the user long press the power button

Answer 1

Go with this

And when you want to capture that event do this

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_POWER) {
        // this is method which detect press even of button
        event.startTracking(); // Needed to track long presses
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_POWER) {
        // Here we can detect long press of power button
        return true;
    }
    return super.onKeyLongPress(keyCode, event);
}

It can be done with broadcast receiver. see this answer
