How to play YouTube video in WebView on Google Glass

问题

I have code like this:

setContentView(R.layout.webview);       
webView = (WebView) findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("https://www.youtube.com/watch?v=_Z5-P9v3F8w");

It'll show the youtube video with the Play button, but none of the Glass gesture can make the video play. Any ideas? Thanks!

Finally figured out how to play Youtube video on Glass!

Intent i = new Intent();
i.setAction("com.google.glass.action.VIDEOPLAYER");
i.putExtra("video_url", "https://m.youtube.com/watch?v=5bWSgFnoCOk"); 
startActivity(i);    

Using WebView can't play the video, using VideoView can only play local MP4 or streaming MP4 (there's some way to hack the MP4 link for a Youtube video, but not reliable). Also, using VideoView can only pause/play the video, but not fast forward or backward. Using the com.google.glass.action.VIDEOPLAYER above solves all the problems WebView and VideoView have.
