Search the forums, as this has been asked before.

Basically you can't really do this because the sample plays back remote video files from a web server that enforces the live stream video protocol for video files. Youtube does not do this, but you can set your own one up.  However this is outside the scope of forum support.

Youtube video URLs usually do not point explicitely to a video file (such as ".mp4" or ".m4v" files), i.e. the URL itself does not contain a path to a video file;

the video playback sample requires you to have an explicit video file path in the URL,

Note that a developer has shared an approach using some library called YouTubeAndroidPlayerApi available at https://developers.google.com/youtube/android/player/
