title: Using Theme.Material.Light.DarkActionBar with Theme.AppCompat.Light.DarkActionBar crashes the app on android L(api v21)
body: <p>Here is how my resources look like</p>
  
  <pre><code>res/values/styles.xml
      &lt;style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"&gt;
          &lt;item name="colorPrimary"&gt;@color/colorPrimary&lt;/item&gt;
          &lt;item name="colorPrimaryDark"&gt;@color/colorPrimaryDark&lt;/item&gt;
          &lt;item name="android:windowNoTitle"&gt;true&lt;/item&gt;
          &lt;item name="windowActionBar"&gt;true&lt;/item&gt;
      &lt;/style&gt;
  </code></pre>
  
  <p>like it says <a href="https://developer.android.com/training/material/get-started.html" rel="nofollow">here</a></p>
  
  <pre><code>res/values-v21/styles.xml
      &lt;style name="AppTheme" parent="android:Theme.Material.Light.DarkActionBar"&gt;
      &lt;/style&gt;
  </code></pre>
  
  <p>and the AndroidManifest.xml has</p>
  
  <pre><code>&lt;application android:icon="@drawable/ic_launcher"
  android:theme="@style/AppTheme" &gt;
  </code></pre>
  
  <p>in my MainActivity.java i inherit from the ActionBarActivity</p>
  
  <pre><code>public class MainActivity extends ActionBarActivity {
  ....
  ...
  }
  </code></pre>
  
  <p>Now when i run the app on KitKat (API 19) the app runs and i see Dark Action bar and the material design but when i run it on Android L (API 21), the app crashes saying <code>java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.</code>. I know this happens because i inherit from <code>ActionBarActivity</code> but if i use an <code>appcompat</code> theme in <code>values-v21/styles.xml</code> then how would i use the material theme?</p>
