title: Android - Remove action button from notification
body: <p>I want to dismiss the notification action buttons (not the whole notification) when clicking on those action buttons. (Lets say: a download notification with stop action button. When click on stop, dismiss stop button and change contentText to 'Download canceled')</p>
  
  <p>The only thing it comes to my mind is to cancel notification and notify another one with the same id, but this seems to be an ugly workaround...</p>
  
  <p>So, is there any way to remove action buttons from notifications?</p>
  
  <p>(i think there is no need to put any code, but I will if its necessary...)</p>
