title: Where is getApiClient on BaseGameActivity?
body: <p>The Google documentation at <a href="https://developers.google.com/games/services/android/init" rel="nofollow">https://developers.google.com/games/services/android/init</a> says that </p>
  
  <blockquote>
    <p>Your game must have a reference to the GoogleApiClient object in order
    to make any API calls to the Play Games services. During its
    activity's lifecycle, your game can retrieve the GoogleApiClient
    object at any time after onCreate(), by calling getApiClient(). For
    example:</p>
    
    <p>Games.Leaderboards.submitScore(getApiClient(), LB_ID, 12345);</p>
  </blockquote>
  
  <p>Initially the page also says:</p>
  
  <blockquote>
    <p>The BaseGameActivity class wraps the GoogleApiClient, reducing the complexity of setting up a connection with the Google Play servers and managing user sign-in.</p>
  </blockquote>
  
  <p>However, I can't find <code>getApiClient()</code> in <code>BaseGameActivity</code> or in <code>GameHelper</code>. Where is it?</p>
