With an update of Xamarin the namespace that starts with Xamarin. causes build errors in NovaHomeBadger:
_context.ContentResolver.Insert(Android.Net.Uri.Parse(ContentUri), contentValues);
Android.Net.Uri cannot be found anymore because it searches in Xamarin.Android.Net (which is new in Xamarin 6.1).
Change or remove Xamarin. fixes the issue.
See: https://developer.xamarin.com/releases/android/xamarin.android_6/xamarin.android_6.1/
@ Breaking changes:
Possible compilation errors when projects use a Xamarin. namespace, because of conflict with the new Xamarin.Android.Net namespace.
