title: Disable android system volume overlay
body: <p>Is there a way to disable/override the volume overlay/toast ? (its not actually a real toast) </p>
  
  <p>I want to replace it, I already wrote a system Overlay which acts like the original, plus there are more sliders. </p>
  
  <p>Now I just want to disable the original <em>(image below)</em> so it is not displayed.</p>
