title: VideoView inside fragment causes black screen flicking
body: <p>We have an Android application running on Android API 4.0. One of the activities has a layout that divides the screen in 2 parts. On the left side we have a static part with some buttons. On the right side we have a FrameLayout that will switch to the corresponding fragment depending on the button that is pressed.</p>
  
  <p><strong>Problem:</strong>
  One of the fragments on the right side contains a VideoView. When the user clicks on the button to show this fragment the fragment is shown and the video immediately starts playing however: upon rendering this fragment the complete screen flickers in black which is very annoying.</p>
  
  <p>Here is some code of the VideoFragment class:</p>
  
  <pre><code>public class VideoFragment extends Fragment {
  
      public VideoView videoView;
  
      private ExternalVideo mVideo;
      private boolean mVideoExists;
      private String mDestination;
  
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          mDestination = ApplicationParams.MEDIA_STORAGE_PATH + "videos/"
                  + FilenameUtils.getBaseName(((DetailActivity)getActivity()).getProduct().getVideoUrl())
                  + "."
                  + FilenameUtils.getExtension(((DetailActivity) getActivity()).getProduct().getVideoUrl());
  
          File file = new File(mDestination);
          mVideoExists = file.exists() &amp;&amp; file.isFile();
      }
  
      @Override
      public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
          View view;
  
          if (mVideoExists) {
              getActivity().getWindow().setFormat(PixelFormat.TRANSLUCENT);
              view = inflater.inflate(R.layout.video, null);
              mVideo = new ExternalVideo(mDestination);
  
              videoView = (VideoView) view.findViewById(R.id.video_video);
  
              MediaController mediaController = new MediaController(getActivity());
              mediaController.setAnchorView(videoView);
  
              videoView.setMediaController(mediaController);
              videoView.setVideoPath(mVideo.getFullPath());
              videoView.requestFocus();
              videoView.setVisibility(View.VISIBLE);
  
              videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                  public void onPrepared(MediaPlayer mp) {
                      videoView.start();
  
                  }
              });
          } else {
              TextView textView = new TextView(getActivity());
              textView.setText(getActivity().getString(R.string.videofragment_video_coming_soon));
              textView.setPadding(50, 50, 50, 50);
              view = textView;
          }
  
          return view;
      }
  
  }
  </code></pre>
  
  <p>Here is the layout of the video fragment:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  
  &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="match_parent"&gt;
      &lt;VideoView android:id="@+id/video_video"
                 android:layout_width="fill_parent"
                 android:layout_alignParentRight="true"
                 android:layout_alignParentLeft="true"
                 android:layout_alignParentTop="true"
                 android:layout_alignParentBottom="true"
                 android:layout_height="fill_parent"/&gt;
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>Does anyone have an idea what could be causing this flickering issue upon rendering the fragment that contains the VideoView? A solution would be appreciated!</p>
  
  <p><strong>EDIT1:</strong> If I click on the fragment where the VideoView is on the screen flickers in the beginning. When I then navigate to anoter fragment and go back to the one containing the VideoView the flicker is gone.</p>
