Embed config is not supported in RemoteEmbeddedPlayer?

Whenever I'm trying to open Youtube player in my app, onInitializationSuccess() function is always called. But it shows a blank screen.

First this error appears:

W/YouTubeAndroidPlayerAPI: Forcefully created overlay:affq@82a17f5 helper:Lazy@9b7098a view:null status: ....... {...}

and then:

E/YouTubeAndroidPlayerAPI: Embed config is not supported in RemoteEmbeddedPlayer.

Here is my code:

FragmentManager fragmentManager = ((AppCompatActivity)this.context).getSupportFragmentManager();    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();    Fragment  youtubeFragment = new YouTubePlayerSupportFragment();    fragmentManager.beginTransaction().add(R.id.GlideLayout ,youtubeFragment).commit();    utubevw = (YouTubePlayerSupportFragment) youtubeFragment;    utubecontainer = imageLayout.findViewById(R.id.youtubecontainer);    utubecontainer.setVisibility(View.VISIBLE);    mOnInitializeListener = new YouTubePlayer.OnInitializedListener() {        @Override        public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {            youTubePlayer.cueVideo("_8kExcHqFi4");            Log.i("youtube", "Successful");        }        @Override        public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {            Log.i("youtube:Fail", youTubeInitializationResult.toString());        }    };    utubevw.initialize(String.valueOf(R.string.googleapikey), mOnInitializeListener);

Searched everywhere, even posted in Github, but couldn't find a solution.

FYI - I don't want to use Webview to play Youtube.
