title: Activity does not animate on Finish(). It just disappears
body: <p>I spent many hours trying to find out why my Activities do not show any transition when calling Finish(). The default show/appear animation works as expected though.</p>
  
  <p>I don´t want to override pending transitions with a custom animation. I just want the default transitions.</p>
  
  <h1>Update</h1>
  
  <p>I created a brand new project with a couple of regular activities and they transition-out as expected. Then I created 2 <code>AppCompatActivity</code> and added the support libraries to the project and voilá, same problem. </p>
  
  <p>This is what my Theme looks like on <code>values</code>:</p>
  
  <pre><code>&lt;style name="ChefTheme" parent="ChefTheme.Base"&gt;
  &lt;/style&gt;
  
  &lt;style name="ChefTheme.Base" parent="Theme.AppCompat.Light.NoActionBar"&gt;
    &lt;item name="colorPrimary"&gt;@color/primary&lt;/item&gt;
    &lt;item name="colorPrimaryDark"&gt;@color/primaryDark&lt;/item&gt;
    &lt;item name="colorAccent"&gt;@color/accent&lt;/item&gt;
    &lt;item name="android:windowBackground"&gt;@color/window_background&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>and this is on <code>values-v21</code>:</p>
  
  <pre><code>&lt;style name="ChefTheme" parent="ChefTheme.Base"&gt;
    &lt;item name="android:windowIsTranslucent"&gt;true&lt;/item&gt;
    &lt;item name="android:windowDrawsSystemBarBackgrounds"&gt;true&lt;/item&gt;
    &lt;item name="android:windowContentTransitions"&gt;true&lt;/item&gt;
    &lt;item name="android:windowAllowEnterTransitionOverlap"&gt;true&lt;/item&gt;
    &lt;item name="android:windowAllowReturnTransitionOverlap"&gt;true&lt;/item&gt;
    &lt;item name="android:windowSharedElementEnterTransition"&gt;@android:transition/move&lt;/item&gt;
    &lt;item name="android:windowSharedElementExitTransition"&gt;@android:transition/move&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>Any idea why could this be happening?</p>
