Android WebView play video (including full screen playback)

Recent project development has used the function of WebView play video, summed up the mistakes in development, these errors in the development is and easy to encounter, so I summed up here, I hope you see not making similar mistakes, as far as possible to improve the development efficiency:

This demo I also refer to the online write a better demo, after summing up the changes, written out.

The following code is appropriate:
