Hi Cliffus, I have exactly the same issue here. A service handing the MediaPlayer, and I would like to disconnect/reconnect the video when activities are launched/stopped. I tried several strategies : - creatig a "false" Surface Holder that would hide the surface destroyed and delegating to the real SurfaceHolder when set. - Using setDisplay(null), not setting it to null when surface is destroyed...
None of these strategies seems to work, at least on the two devices I am testing. IMHO, when using setDisplay(null) or when the Surface becomes invalid, the MediaPlayer is not working for Video anymore... I see two possibilities to solve this : - use two separate streams, one for video, the other for audio, and enable only video when creating the activities - when creating an activity if setDisplay() has already been called once, create a new MediaPlayer, prepare it and when it is ready, replace the old MediaPlayer... but unfortunatly, it will create an Audio artifact :( Do you have other ideas ?
