title: Using the YouTube API within a fragment
body: <p>I using the new YouTube API in my project. Using the example of the documentation, it works correctly:</p>
  
  <pre><code>public class Test extends  YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {
  
      String urlVideo;
  
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.main);
  
          urlVideo="5lbVNYAeFiQ";
  
          YouTubePlayerView youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);
          youTubeView.initialize("MY_API_KEY", this);
  
      }
  
      public void onInitializationFailure(Provider arg0,YouTubeInitializationResult arg1) {
          Toast.makeText(this, "Error ", Toast.LENGTH_LONG).show();  
      }
  
      public void onInitializationSuccess(Provider arg0, YouTubePlayer arg1,boolean wasRestored) {
          if (!wasRestored) {
              arg1.loadVideo(urlVideo);
          }
  
      }
  }
  </code></pre>
  
  <p>But in my project, I'm using a main activity that contains a ViewPager
  The ViewPager shows fragments, the problem is when I want to show YouTubePlayer within one fragment of ViewPager.
  Normally, an activity that uses youtube, extending YouTubeBaseActivity.</p>
  
  <pre><code>extends YouTubeBaseActivity implements ... { 
  </code></pre>
  
  <p>My question is, how I can show YouTube Player in an activity that extends from fragments?</p>
  
  <p>I searched, but can not find information about my problem.</p>
  
  <p>I sincerely appreciate the help.</p>
  
  <p>Best regards</p>
