@depri Thank you for reporting this issue. I changed the behaviour of the HiddenCameraFragment.java and HiddenCameraActivity.java. Now both releases the camera on onPause() of the activity/fragment.

As I think there is no point to keep acquiring camera if while the app is in the background. If the application wants to capture an image while the app is in the background, it can use HiddenCameraService.java for that.

I made changes in latest sample apk and it doesn't crash now. You can check and report me back if the issue still exists.
