CameraView Scaling - Android

[Jake-Derrick]

I noticed that for the Android camera PreviewView, the ScaleType was set to ScaleType.FitCenter. Was there a reason this was picked over the default value of ScaleType.FillCenter? I feel ScaleType.FillCenter might be more expected and seems to align better with the ios view too.

Fill Center looks better and matches the same behavior as iOS. That looks like a good idea to implement.

If you capture an image what is the result? I can see that both options in the preview isn't showing all of the same detail - this might be down to a slightly different camera angle.

I think the best option is for the preview to most accurately match the captured image and not other platforms. The being said I think we should probably let the developer decide and make this configurable

That's a good point. Both the Android with FillCenter and iOS will include extra detail in the captured image that isn't shown in the PreviewView. I think for Android ViewPort can be used align the PreviewView and the captured image, but I haven't used it yet to see how it works.

At any rate, I agree making it configurable would probably be the best way to go.
