Apps video playback displays blank screen with only audio?

[krishnaveni]

I have to develop an one android application.

here i have to play the video on full screen mode and normal mode.i have using youtubeplayersupportfragment.

Here the video is playing well on full screen mode. The Same video is playing well on normal mode also.Here i have facing one problem.

The problem is, When I try playing from the video, all I get is blank video but I get all the audio and subtitles. If I hit the back button, I see the last video frame before the video player closes.

Why am facing these issue ???

Why am getting these error ???? please give me any solution ??

am using following code:

[HIGH]<fragment
android:name="com.google.android.youtube.player.YouTubePlayerSupportFragment"
android:id="@+id/youtube_fragment"
android:layout_width="match_parent"
android:layout_below="@+id/title"
android:layout_height="wrap_content"/>
[/HIGH]
I have using following code on my activity:

[HIGH]_Video = articlevideo.substring(1);

FragmentManager fragmentManager = getChildFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager
.beginTransaction();
YouTubePlayerSupportFragment fragment = new YouTubePlayerSupportFragment();
fragmentTransaction.add(R.id.youtube_fragment, fragment);
fragmentTransaction.commit();


fragment.initialize(DeveloperKey.DEVELOPER_KEY, new OnInitializedListener() {


public void onInitializationSuccess(YouTubePlayer.Provider provider,
YouTubePlayer player, boolean wasRestored) {
if (!wasRestored) {
player.cueVideo(_Video);
}
}
private static final int RECOVERY_DIALOG_REQUEST = 1;
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider,
YouTubeInitializationResult errorReason) {


if (errorReason.isUserRecoverableError()) {
errorReason.getErrorDialog(getActivity(), RECOVERY_DIALOG_REQUEST).show();
} else {
String errorMessage = String.format(getString(R.string.error_player), errorReason.toString());
Toast.makeText(getActivity(), errorMessage, Toast.LENGTH_LONG).show();
}
}
});
