Video Freeze after lock screen on SurfaceView using SurfaceView and MediaPlayer

Question

I was trying to use SurfaceView and MediaPlayer to Display video on Android.

I got a bug now that if I press the power button to lock the screen and then unlock it, The Video displayed on the MediaPlayer is gone and there is only sound. Normally for this situation the surfaceView would be somehow freeze to the last frame of the video before I lock the phone.

It works fine when I hide the screen(such as go to home and open another application) But it just does not work when I lock the phone. I think they both pass the onPause and onResume so I do not understand why would there be different logic.

I'd like to know if there is a solution to solve my problem.

Thanks!

OK, I fix this in a weird way, I think it is probably a bug of Android. Don't have time to do enough testing on this.

First surely as @fadden says you need to have a mMediaPlayer.setDisplay(myHolder) elsewhere not in the surfaceChanged or surfaceCreated since they may not be called while resume from locked screen.

For me the problem still persist after I changed it this way. Here is what I changed that solved the problem: Instead of mMediaPlayer = new MediaPlayer(), we should use mMediaPlayer = MediaPlayer.create(MediaActivity.this, fileUri)
