            The camera object itself seems to be null. Are you sure it's initialized correctly ?

              Ok. if i have not initialized it, can you help me on how to initialize it?
              I have done the initialization as below:

                  mCamera = new QCamera(this);
                  mCameraViewFinder = new QCameraViewfinder(this);
                  mCameraImageCapture = new QCameraImageCapture(mCamera,this);
                  mCamera->start();

                It's not your mCamera object that is null, it's your camera object.

                    It's your own custom class, how can I know where you use it or how you use it ?

                        Then don't create a new QCamera each time you change the resolution.
