title: GoogleAccountCredential include File
body: <p>I recently updated several libraries using the Android SDK Manager and Android Studio. One of my imports is now failing:</p>
  
  <pre><code>import com.google.api.client.googleapis.extensions.android.gms.auth.GoogleAccountCredential;
  </code></pre>
  
  <p>I am wondering what package/library this is supposed to be found in so that I can make sure that is being included in the build path, or so that I can revert to an older version.</p>
  
  <p>I am using Android Studio 1.6.0_45</p>
