Youtube video get stuck while playing in fragment

问题

I am new to Android.I am trying to play youtube video while the fragment loads.That means video should be playing while open the app.When I use this in activity it works(YouTubePlayerView ),but when I use YouTubePlayerSupportFragment video get stuck and not playing properly.

this is the code for youtube:

YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();
    FragmentTransaction transaction =getChildFragmentManager().beginTransaction();
    transaction.add(R.id.youtube_fragment, youTubePlayerFragment).commit();
    youTubePlayerFragment.initialize("AIzaSyA9Kka548d7RZYVBypAy4UWgvDvbUCP16c", new YouTubePlayer.OnInitializedListener() {
        @Override
        public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
            if (!b) {
               YPlayer=youTubePlayer;

               // youTubePlayer.cueVideo("EjvfD61PXAw");
                YPlayer.loadVideo("EjvfD61PXAw");
                YPlayer.play();
            }


        }

        @Override
        public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {

        }
    });
