title: Android Drop Shadow on View
body: <p>I have done some extensive searching for code examples on this but cannot find anything. </p>
  
  <p>In particular, I am looking to add a shadow to a png drawable I am using in an ImageView.  This png drawable is a rounded rect with transparent corners.</p>
  
  <p>Can somebody please provide a code example of how to add a decent drop shadow to a view either in code or XML?</p>
