title: Android windowEnterAnimation attribute does not exist
body: <p>I've been trying to follow this answer for <a href="https://stackoverflow.com/questions/9305581/how-to-make-a-dialog-slide-from-bottom-to-middle-of-screen-in-android">adding an animation to a dialog box</a>.  However I'm getting an error on the first style addition.</p>
  
  <p>I've added the following to <code>res/values/styles.xml</code> (not completely sure if this is correct)</p>
  
  <pre><code>&lt;style name="DialogAnimation"&gt;
      &lt;item name="android:windowEnterAnimation"&gt;@anim/slide_down_dialog.xml&lt;/item&gt;
      &lt;item name="android:windowExitAnimation"&gt;@anim/slide_out_up&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>The first item, <code>android:windowEnterAnimation</code>, does not seem to exist when I tab complete <code>android:</code>.  This also applies to <code>android:windowExitAnimation</code>.  The error I receive in the XML file is:</p>
  
  <p><code>error: Error: No resource found that matches the given name (at 'android:windowEnterAnimation' with value '@anim/slide_down_dialog.xml').</code></p>
  
  <p>All the questions I've found regarding animation like this uses <code>windowEnter/ExitAnimation</code>.  I looked at the <a href="http://developer.android.com/reference/android/R.attr.html" rel="nofollow noreferrer">android docs</a> and it supposedly has this attribute, but I cannot for the life of me get it to appear.  </p>
  
  <p>Thanks in advance for any help/advice.  If this is a duplicate please point me in the right direction, I couldn't find any related questions.</p>
