title: Android - How to prevent the phone screen from turning on when volume or camera key is pressed?
body: <p>I have an activity that shows up when the phone screen goes to sleep/turns off ie turns black.
  For some reason, the phone turns on when the volume buttons or the camera buttons are pressed. By turns on, I mean the screen wakes up or comes back from the black screen state.</p>
  
  <p>I've tried using dispatchKeyEvent(KeyEvent event) and the buttons are disabled on the activity, but they still wake up the phone.</p>
