Android How to listen for Volume Button events?

I don't know if you can get long press events for the hardware keys.

I've used this code to listen for the volume button before.

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

If that doesn't work for you let us know what device you are testing on.

Kotlin

override fun onKeyDown(keyCode: Int, event: KeyEvent?): Boolean {
    if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) { 
        // Do something
    }
    return true
}

how to create a service, that would be listening to the volume button?

What do you think, is that possible?

No. You cannot listen for volume button presses in a service.
