Android: How to properly initialize YouTube Player inside activity?

Question

I am trying to initiate an YouTube player inside an activity. However from time to time I keep getting this exception:

Fatal Exception: java.lang.IllegalStateException YouTubeServiceEntity not initialized

Here is how I try to initialize the youtube player in my activity. (this is done inside OnCreate() )

 try {
        final YouTubePlayerView youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);

        youTubeView.initialize("KEY", new YouTubePlayer.OnInitializedListener() {
            @Override
            public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean Boolean) {
                if(ad==null || ad.getVideo_urls() == null)
                    return;

                if (!Boolean)
                {
                    try {
                        if (ad.getVideo_urls() != null && ad.getVideo_urls().length() > 0) {
                            String url = ad.getVideo_urls().getString(0);
                            if (url.contains("youtube")) {
                                String id = ad.getVideo_urls().getString(0).split("embed/")[1];
                                youTubeView.setVisibility(View.VISIBLE);
                                MyYouTubePlayer = youTubePlayer;
                                MyYouTubePlayer.cueVideo(id);
                            }
                        } else {
                            youTubeView.setVisibility(View.GONE);
                            Log.i(Constants.getTag(), "Video not found");
                            //Making sure the MyYouTubePlayer is null and if not is being released
                            if(MyYouTubePlayer != null)
                            {
                                MyYouTubePlayer.release();
                            }
                        }
                    }
                    catch (JSONException e) {
                        youTubePlayer.release();
                        e.printStackTrace();
                    }
                }
            }

            @Override
            public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
                youTubeView.removeAllViews();
            }
        });

    } catch(Exception e){
        e.printStackTrace();
        Log.e("Youtube", "error initializing youtube");
    }

The weirdest thing is that this issue is not persistent. It just happens from time to time and I have no idea why. Can you tell me what could be causing this?

Here is also the logcat:

I am also facing this bug right now in my app. The problem happens when the user quit the Youtube player fragment containing activity without being it properly initialized. It is quite random and not easy to reproduce.

I am simply using try-catch to avoid it and luckily, it has not been reproduced yet.

try {
    mYouTubePlayerFragment.initialize(DEVELOPER_KEY, this);
} catch(IllegalStateException w){}

Again It may not be the sure solution.

One solution may be to check in OnBackPressed() whether the you-tube player has been initialized.

isInitializationComplete = false

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
    isInitializationComplete = true;
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider,
                                    YouTubeInitializationResult youTubeInitializationResult) {
    isInitializationComplete = true;
}
 @Override
public void onBackPressed() {
   if(!isInitializationComplete) return; 
}

Try out monkey to reproduce it more often.

adb shell monkey -p com.packagename -v 500

I had this error as well, i worked around it by creating a custom class that extends YouTubePlayerSupportFragment , maybe my code does help you, which is working fine for me.

I initialize my youtube player like so:

private String currentVideoID = "<your video id>";
private YouTubePlayer activePlayer;

private void init() {

    initialize(ConstantsRepository.GOOGLE_API_SERVER_KEY, new YouTubePlayer.OnInitializedListener() {

        @Override
        public void onInitializationFailure(YouTubePlayer.Provider arg0, YouTubeInitializationResult arg1) {
            // youtube is not installed
        }

        @Override
        public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
            activePlayer = player;
            activePlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
            if (!wasRestored) {
                activePlayer.loadVideo(getArguments().getString("url"), 0);
            }
        }
    });
}

In your activity provide a youtube fragment in layout.xml and do the following replacement in onCreate:

 YTPlayerFragment myFragment = YTPlayerFragment.newInstance("oVkK3X9zMyI");
        getFragmentManager().beginTransaction().replace(R.id.youtube_container, myFragment).commit();
