I have an intruder problem. I have created a xamarin form solution with monoandroid 8.1 and .net standard 2.0 and everything was going fine, but once I added UI test project and add android project as reference I saw 4 errors and when I built it build was successful but the error was still visible.
When I build it in app center it fails and shows me these 4 errors: errors list
Log from app center
