title: How to customize the appearance of the Facebook Share Button in the SDK?
body: <p>I've been all over the internet and can't seem to get a direct answer or tutorial, so this is my final attempt to get an answer.</p>
  
  <p>I have an android app integrated with Facebook SDK.  I added a share button, but I don't like the look of it.  I've seen other apps with different looking Facebook share buttons, but for some reason I don't see any doc on how to do it.  I tried changing the .png in the drawable folder of the Facebook SDK but that didn't work.</p>
  
  <p>Anytime I would assign my own .png, it will render on top of a native appearance.</p>
  
  <p>Can someone help step by step.  It would greatly be appreciated.</p>
