I'm trying to use a native android library called "ImageCropper" available here: https://github.com/ArthurHub/Android-Image-Cropper
I created android bindings, but when I try to consume it from XF custom rendered, it throws an error saying: "java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/appcompat/app/AppCompatActivity"
I'm compiling my XF app with target version set to API 29. Not sure what I'm missing or how would I proceed to fix this issue. Any suggestions are heartly appreciated. Thanks.
PS: XF custom renderer: https://pastebin.com/85Mdsy8c
