Found this crash on v0.13.6.
This PR fixed the exception when the device is trying the perform view onMeasure() but the camera is not opened yet.
So the getCameraPreviewResolution() method will return
null(which is fine because the CameraView will adjust later), however, if we also want to invert PreviewSizes, the NullException comes up.The solution is simply adding the null check.
