Having this issue when trying to build Xamarin.Android project (Xamarin.Forms)
Project App.Droid cannot build using TargetFrameworkVersion v8.1 because it is not supported. Please change your Xamarin.Android project to target an API version that is supported.
How do I resolve this issue?
I think I have installed SDKs I need, screenshot is here
After upgrading my VS2017 v.15.3.5 to v.15.7.5, I was able to install newer Android SDKs and tooling and all went well after that.
