title: Google Player Game Service Error: Can't build the sample game
body: <p>I can't build the sample game <code>TypeANumberChallenge</code> provided by Google (see <a href="https://github.com/playgameservices/android-basic-samples/tree/master/BasicSamples/TypeANumber" rel="nofollow noreferrer">GitHub</a>). Got the following error message:</p>
  
  
  
  <pre class="lang-none prettyprint-override"><code>The project was not built since its build path is incomplete. Cannot find the class file for com.google.android.gms.games.GamesClient. Fix the build path then try building this project
  
  The type com.google.android.gms.games.GamesClient cannot be resolved. It is indirectly referenced from required .class files    MainActivity.java   /TypeANumber/src/com/kerrywei/games/tanc
  </code></pre>
  
  <p>I did include the project library <code>BaseGameUtils</code> and google-play-services-lib as described by <a href="https://github.com/playgameservices/android-basic-samples" rel="nofollow noreferrer">readme</a> and <a href="https://developers.google.com/android/guides/setup" rel="nofollow noreferrer">Google Play Services Guides</a>, but still got the error, and can't just compile...</p>
  
  <p>Update:
  I tried to remove <code>TypeANumberChallenge</code> and redo the whole process and got a new error when trying to add <code>BaseGameUtils</code> as library:</p>
  
  <pre class="lang-none prettyprint-override"><code>An internal error occurred during: "Android Library Update".
  Path must include project and resource name: /BaseGameUtils
  </code></pre>
