title: MoPub cannot find com.mopub.mobileads.VastVideoInterstitial
body: <p>I have integrated the full SDK from MoPub, including copying over the necessary adapters into the source for my MoPub module.</p>
  
  <p>However, when I request an ad from MoPub, I keep getting an error:</p>
  
  <pre><code>Couldn't locate or instantiate custom event: com.mopub.mobileads.VastVideoInterstitial.
  </code></pre>
  
  <p>The problem is that <code>VastVideoInterstitial</code> is most definitely included, so I am baffled as to why MoPub cannot find it. My <code>AndroidManifext.xml</code> includes all the activities I could find for the MoPub module:</p>
  
  <pre><code>    &lt;activity android:name="com.mopub.mobileads.MoPubActivity" android:configChanges="keyboardHidden|orientation|screenSize"/&gt;
      &lt;activity android:name="com.mopub.mobileads.MraidActivity" android:configChanges="keyboardHidden|orientation|screenSize"/&gt;
      &lt;activity android:name="com.mopub.common.MoPubBrowser" android:configChanges="keyboardHidden|orientation|screenSize"/&gt;
      &lt;activity android:name="com.mopub.mobileads.MraidVideoPlayerActivity" android:configChanges="keyboardHidden|orientation|screenSize"/&gt;
      &lt;activity android:name="com.google.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" /&gt;
      &lt;activity android:name="com.millennialmedia.android.MMActivity" android:theme="@android:style/Theme.Translucent.NoTitleBar" android:configChanges="keyboardHidden|orientation|keyboard" /&gt;
      &lt;activity android:name="com.millennialmedia.android.VideoPlayer" android:configChanges="keyboardHidden|orientation|keyboard" /&gt;
      &lt;activity android:name="com.mopub.mobileads.BaseVideoPlayerActivity"  android:configChanges="keyboardHidden|orientation|keyboard" /&gt;
      &lt;activity android:name="com.google.android.gms.ads.AdActivity"
          android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/&gt;
  </code></pre>
  
  <p>What am I missing here to show VAST video interstitials? I could turn them off in MoPub, but this seems to be a poor option as it would cause the eCPM for my app to drop.</p>
  
  <p>How can I solve this issue in Android?</p>
