title: Android: When watching a youtube video fullscreen I press back and the Activity finish
body: <p>I've read all around the way of leaving fullscreen from a YouTube video is by pressing back, but in my <code>Activity</code> it's not working like this but I'd like it to.</p>
  
  <p>I post you the code:</p>
  
  <pre><code>public class MainActivity extends YouTubeFailureRecoveryActivity {
      public static String prefix = "https://gdata.youtube.com/feeds/api/playlists/";
      public static String sufix = "?v=2&amp;alt=jsonc";
  
      private String myPlayList = "PLZGKlf2ZwY7ua0C2oeUaXQKeLKNGy3mkh";
  
      private VideosListFragment videosFragment;
  
      // The next video to play
      private Video actualVideo;
  
      // This is the handler that receives the response when the YouTube read
      private Handler responseHandler;
  
  
      /** Called when the activity is first created. */
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
  
          videosFragment = (VideosListFragment) getFragmentManager().findFragmentById(R.id.videosListView);
          getUserYouTubeFeed();
  
      }
  
      @Override
      public void onInitializationSuccess(YouTubePlayer.Provider provider,
              YouTubePlayer player, boolean wasRestored) {
          if (!wasRestored) {
              player.loadVideo(actualVideo.getVideoId());
          }
      }
  
      @Override
      protected YouTubePlayer.Provider getYouTubePlayerProvider() {
          return (YouTubePlayerFragment) getFragmentManager().findFragmentById(
                  R.id.youtube_fragment);
      }
  
      public void getUserYouTubeFeed() {
          responseHandler = new Handler() {
              public void handleMessage(Message msg) {
                  populateListWithVideos(msg);
              };
          };
          // We start a new AsyncTask that does its work on its own thread
          // We pass in a handler that will be called when the task has finished
          LoadPlayListElements bgTask = new LoadPlayListElements(responseHandler);
          bgTask.execute(myPlayList);
  
      }
  
      /**
       * This method retrieves the Library of videos from the task and passes them
       * to our ListView
       * 
       * @param msg
       */
      private void populateListWithVideos(Message msg) {
          Library lib = (Library) msg.getData().get(
                  LoadPlayListElements.LIBRARY);
          VideosAdapter videos = new VideosAdapter(this, lib.getVideos());
          videosFragment.setListAdapter(videos);
      }
  
      @Override
      protected void onStop() {
          // Make sure we null our handler when the activity has stopped
          responseHandler = null;
          super.onStop();
      }
  
      public void setVideo(Video _item, boolean _activate) {
          actualVideo = _item;
          if (_activate){
              YouTubePlayerFragment fragment = (YouTubePlayerFragment) getFragmentManager()
                      .findFragmentById(R.id.youtube_fragment);
              if (fragment != null &amp;&amp; fragment.isInLayout()) {
                  fragment.initialize(DeveloperKey.DEVELOPER_KEY, this);
              }
          }
      }
  }
  </code></pre>
  
  <p>and the layout:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="horizontal"
      android:paddingBottom="@dimen/activity_vertical_margin"
      android:paddingLeft="@dimen/activity_horizontal_margin"
      android:paddingRight="@dimen/activity_horizontal_margin"
      android:paddingTop="@dimen/activity_vertical_margin" &gt;
  
      &lt;fragment
          android:id="@+id/videosListView"
          android:layout_width="0dp"
          android:layout_height="match_parent"
          android:layout_weight="1"
          android:layout_marginTop="?android:attr/actionBarSize"
          class="com.vivoenmimundo.sc2hotsepicreplays.ui.phone.fragment.VideosListFragment" &gt;
      &lt;/fragment&gt;
  
      &lt;fragment
        android:name="com.google.android.youtube.player.YouTubePlayerFragment"
        android:id="@+id/youtube_fragment"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="2"
        android:layout_gravity="center_vertical"/&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>Any idea? I've tried to not do anything too strange, just copy/paste from YouTube's API examples.</p>
