YouTubeAndroidPlayer on Android crashes when playing ()

Question

I am trying to embed YouTubePlayerView in an android app. I am using YouTubePlayerAPI v1.2.1 in Android API 17.

It comes with a warning before the failure, which probably has something to do with it.

A crash occurs when player.play () is called. However, I still do not know how to play.

Any ideas?
