Problem with conversion in Visual Studio - proximity-sdk-1.0.5.aar

I have problem with conversion in Visual Studio - proximity-sdk-1.0.5.aar to *.dll file. I need it to Xamarin for Android 10. There are missing methods: onError or OnEnter in the ProximityZoneBuilder object. Is there anybody who sort out that problem? Please help me. I include screenshot from visualstudio.

Hi Godzio. I’m a Xamarin developer too. I tried a couple of months ago add Estimote to my Xamarin Forms App. But I failed. What about you? Did you succeeded ? Please let me know?
