how to capture the camera shutter open event from the camera phones?

[kanishk_408]

Is there a way to capture the camera shutter open event from the camera phones that have camera. The issue is once the camera shutter opens the app is either killed or backgrounded. Is there a way to prevent the app from getting killed /backgrounded or if the app is backgrounded , bring it to foreground ?
