You *should immediately release the camera when you don't need it anymore, maybe as soon as the new wallpaper is set. But you must release the camera when your activity looses focus.

I am override the onVisibilityChanged(boolean visible) change method in Engine class to solve the issue.

public void onVisibilityChanged(boolean visible) {
    // TODO Auto-generated method stub
    super.onVisibilityChanged(visible);
    if (visible) {
        try {
             "OPEN THE CAMERA OBJECT"
        }catch(Exception e){
             e.printStackTrace();
        }
    }
    else {
         try {
             //release the camera obj
         }catch (RuntimeException e) {
             // TODO Auto-generated catch block
             e.printStackTrace();
         }
    }
}
