How to properly lock/unlock camera when drawing on SurfaceView?

Just add something like this to surfaceCreated callback: if (camera! = null) { camera.release(); } camera = Camera.open(); camera. SetDisplayOrientation(90); try { camera.

SetPreviewDisplay(holder); } catch (Exception e) { } And then inside onPause() add release and call to callback: camera.release(); surfaceCreated(surfaceHolder) Now it works like a charm! Cheers!

Apparently surface is destroyed each time I close the app leaving it in background. So next time I reopen it, I need to create surface again and start drawing camera output on it. Hope it helps!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
