title: Removing the secondary icon from android notification
body: <p>How can I remove the secondary smaller icon on the bottom right of a notification? Since it's required that we call the setSmallIcon method for the notification, we can’t just remove the call for this method. </p>
  
  <p>Is there any way to remove the secondary icon while retaining it on the status bar? Do we have to call setStyle and set a custom style for the notification?</p>
