title: Android App crash with BaseGameActivity
body: <p>So, somewhat hard to ask. 
  I wanna use the google play game service to access a leaderboard for my game.
  I tried to use BaseGameActivity like it is shown here <a href="https://developers.google.com/games/services/android/init">Accessing the Games APIs</a></p>
  
  <p>Tried a few things, did some search but cannot figure out the problem. My App crashes when the BaseGameActivity is started. 
  Log error shows:</p>
  
  <pre><code>03-10 17:44:54.071: E/AndroidRuntime(31435): FATAL EXCEPTION: main

  <p><strong>Answer:</strong>
  I had to do two metadata entrys about the appid in the manifest.
  The Log without filters listed the corresponding errors</p>
  
  <p>The two entries were</p>
  
  <pre><code>&lt;meta-data
          android:name="com.google.android.gms.games.APP_ID"
          android:value="@string/app_id" /&gt;
      &lt;meta-data
          android:name="com.google.android.gms.appstate.APP_ID"
          android:value="@string/app_id" /&gt;
  </code></pre>
  
  <p>only one of these entries were mentioned in the tutorial.</p>
