When targetting SDK level 28 or higher, calling CropImageView's SetCropShape with CropImageView.CropShape.Oval results in an java.lang.IllegalArgumentException: Invalid Region.Op - only INTERSECT and DIFFERENCE are allowed exception.

At:
at android.graphics.Canvas.checkValidClipOp(Canvas.java:779) at android.graphics.Canvas.clipPath(Canvas.java:1007) at com.theartofdev.edmodo.cropper.CropOverlayView.drawBackground(CropOverlayView.java:635) at com.theartofdev.edmodo.cropper.CropOverlayView.onDraw(CropOverlayView.java:579)

This was working correctly while targeting earlier SDK versions.

After a quick investigation this is because ArthurHub/Android-Image-Cropper 2.7.0 (which is used by the binding) uses Region.Op.XOR which isn't supported anymore.

This has been fixed in the 2.8.0 version of the library and it is compatible with SDK level 28.
To fix this issue, the bindings would need to be updated to the 2.8.0 version.

I tried updating the bindings myself by forking the project, but I've run into the problem where most of the classes don't appear in the final binding or the api.xml file so it's not working.

Can you add this library into nuget please?

Test

I am able to see the picture taken then the crop bound box appears but there is no "Crop Button". Thus, only way to return to invoking activity is by pressing the back key which cancels the process. Such a good library but can't be used because of this!
