I\'ve created a basic xamarin.forms project (with PCL code sharing strategy) and I\'m getting error for the following two lines in MainActivity::OnCreate(
This happened to me when I included two files into "layout" folder: Tabbar.axml and Toolbar.axml. Following the Xamarin documentation at: https://docs.microsoft.com/en-us/xamarin/xamarin-forms/platform/android/appcompat-material-design
I solved the problem just right clicking in those files, selecting Properties and changing the Build Action to AndroidResource.
