How to freeze camera preview

[leonjohancool]

Hi all,

I want to pause the camera preview when the user touches the screen, and the last frame has to stay visible. When I use camera.stopPreview() method, the camera view is lost. I tried using freeze() and unfreeze methods which are methods of surface class but they didn't work.

Has anyone used these methods? I haven't been able to find any information about neither on internet nor android api...

Sincerely,
Leon
