title: Android L Circular Reveal on a Dialog
body: <p>I'm trying to create a circular reveal on a <code>Dialog</code>.  I would think that you would be able to get the <code>View</code> in the <code>onCreate</code> of the <code>Dialog</code>, hide it, and then reveal it using <code>ViewAnimationUtils.createCircularReveal</code>.</p>
  
  <p>I'm having issues getting the <code>View</code> due to a <code>requestWindowFeature()</code> error, which I can't seem to resolve.</p>
  
  <p>How exactly do you apply the Material Design Animations to Dialogs?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I have successfully hidden the dialog by applying the <a href="https://developer.android.com/preview/material/animations.html" rel="noreferrer">code here</a> to the <code>dismiss()</code> method.  But when I try to do the circular reveal to show, the view stays invisible.</p>
