Struggling with Youtube Player Support Fragment

Question

Im trying to use the Youtube Player Support Fragment in a fragment but the app always crash (NullPointerException) and I have not been able to find any similar post to fix i

Answer 1

CzarMatt nailed it. Just to add to his answer though, don't forget you need to call the init() method. To do so follow CzarMatt's code and add one line:

public static PlayerYouTubeFrag newInstance(String url) {    
    PlayerYouTubeFrag playerYouTubeFrag = new PlayerYouTubeFrag();

    Bundle bundle = new Bundle();
    bundle.putString("url", url);

    playerYouTubeFrag.setArguments(bundle);

    playerYouTubeFrag.init(); //This line right here

    return playerYouTubeFrag;
}

Also, since I'm sure people will run into the same issue I did, even though CzarMatt mentioned it above, just to reiterate, when you pass in a URL for the video, you are NOT passing in the youtube URL

That is, with: "youtube.com/watch?v=z7PYqhABiSo&feature=youtu.be"

You are passing in only the video ID

I.e. use: "z7PYqhABiSo"

Since it is Google's own documentation, it knows how to play it just fine with the id.

I ran into this problem before and I believe the issue stemmed from trying to inflate the YouTubePlayerSupportFragment layout. I solved my issue by creating a fragment like this:

public class PlayerYouTubeFrag extends YouTubePlayerSupportFragment {
    private String currentVideoID = "video_id";
    private YouTubePlayer activePlayer;

    public static PlayerYouTubeFrag newInstance(String url) {
        PlayerYouTubeFrag playerYouTubeFrag = new PlayerYouTubeFrag();

        Bundle bundle = new Bundle();
        bundle.putString("url", url);

        playerYouTubeFrag.setArguments(bundle);

        return playerYouTubeFrag;
    }

    private void init() {
        initialize(DeveloperKey.DEVELOPER_KEY, new OnInitializedListener() {

            @Override
            public void onInitializationFailure(Provider arg0, YouTubeInitializationResult arg1) { 
            }

            @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);

                }
            }
        });
    }

    @Override
    public void onYouTubeVideoPaused() {
        activePlayer.pause();
    }
}

And then call an instance of the fragment like this:

PlayerYouTubeFrag myFragment = PlayerYouTubeFrag.newInstance("video_id");
getSupportFragmentManager().beginTransaction().replace(R.id.video_container, myFragment).commit();

Where video_container in my case was an empty frame layout.
