Thank you! This was incredibly helpful, and the only information I could find on using the YouTube API in a fragment.

thank you :)

thank you so much, I have no words but thank you !

`YouTubePlayerSupportFragment youTubePlayFragment=YouTubePlayerSupportFragment.newInstance();
FragmentTransaction transaction=getChildFragmentManager().beginTransaction();

        transaction.add(R.id.youtube_fragment, youTubePlayFragment).commit();  \\ My Error here


        youTubePlayFragment.initialize(YoutubeDeveloperKey, new YouTubePlayer.OnInitializedListener() {
