Problem with camera........

Question

Hi all,

I have one activity in which i have opened device camera and taking pictures after 1 min each.This is working without any problem.Now my camera is always on.When i press either home screen key or call key,my camera activity is going to background.When i again clicking on my application,ideally my camera activity should come to foreground and camera should be opened.

But this is not happening.When i am clicking on my application icon,my application is crashing.

Is anybody know how to solve this problem?

Thanks and Regards.
