Is it possible to create a Service that listens for hardware key presses?
- by VoteBrian
I'd like to run an Android background service that will act as a keylistener from the home screen or when the phone is asleep. Is this possible?
From semi-related examples online, I put together the following service, but get the error, "onKeyDown is undefined for the type Service"
public class ServiceName extends Service {
@Override
public void onCreate() {
//Stuff
}
public IBinder onBind(Intent intent) {
//Stuff
return null;
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if(event.getAction() == KeyEvent.ACTION_DOWN) {
switch(keyCode) {
case KeyEvent.KEYCODE_A:
//Stuff
return true;
case KeyEvent.KEYCODE_B:
//Stuff
return true;
//etc.
}
}
return super.onKeyDown(keyCode, event);
}
}
I realize Android defaults to the search bar when you type from the home screen, but this really is just for a very particular use. I don't really expect to distribute this. Also, it'd be nice to use the camera button to wake the phone.
