Exactly same thing here:

However it looks like this is coming from a combination of Xamarin.Forms + other libraries that use those properties. Probably those libraries need upgrading their android package references.

Can you please attach a small project that demonstrates this issue? Thanks!

I created a new Empty project (PieTest) and updated the Android project to target Pie as well as update all nugets to the latest version. The project built and deployed ok. There are a lot less support library's referenced in the test project.

Probably best to try and identify the package that's causing the issue.

PieTest.zip

I finally got this fixed. It´s not Xamarin.Forms, but a problem in the csproj when upgrading to API 28:

https://stackoverflow.com/questions/55523996/xf-android-project-does-not-build-after-adding-xamarin-forms-visual-material-nug/55552972#55552972

It actually looks like a nuget.exe issue not updating csproj correctly.

IMO you should be able to close this issue @samhouts
