After upgrading Xamarin.Forms library to version 5.0.0.2083 and AndroidX libraries 1.6, my program gets compile error.

Question

Hello!

Yesterday I updated the libraries Xamarin.Forms and AndroidX libraries to versions 5.0.0.2083 and 1.6 accordingly, including Google.Android.Material up to 1.4. When compiling my application, I began to receive an error message:

Mono.Linker.MarkException: Error processing method: 'System.Boolean Xamarin.Forms.Platform.Android.ShellItemRenderer::Google.Android.Material.BottomNavigation.BottomNavigationView.IOnNavigationItemSelectedListener.OnNavigationItemSelected(Android.Views.IMenuItem)' in assembly: 'Xamarin.Forms.Platform.Android.dll' ---> Mono.Cecil.ResolutionException: Failed to resolve System.Boolean Google.Android.Material.BottomNavigation.BottomNavigationView/IOnNavigationItemSelectedListener::OnNavigationItemSelected(Android.Views.IMenuItem)

Got rid of the bug by downgrading the Google.Android.Material library from 1.4 to 1.3.0.1.
Is this a bug of Google.Android.Material version 1.4?

Answer 1

Hello,​

Welcome to our Microsoft Q&A platform!

Is this a bug of Google.Android.Material version 1.4?

No

Please open the Xamarin.Forms nuget packages(version 5.0.0.2083).

Google.Android.Material' version should be >=1.2.1.1 && <1.3.0
