Mono.Linker.MarkException: Error processing method: 'System.Void AndroidX.RecyclerView.Widget.RecyclerView/LayoutManager

Issue

I am trying to debug my Xamarin project. Framework and all packages are up to date. In iOS it works, but in Android NOT. How can I solve this problem:

Mono.Linker.MarkException: Error processing method: 'System.Void AndroidX.RecyclerView.Widget.RecyclerView/LayoutManager::n_OnInitializeAccessibilityNodeInfo_Landroidx_recyclerview_widget_RecyclerView_Recycler_Landroidx_recyclerview_widget_RecyclerView_State_Landroidx_core_view_accessibility_AccessibilityNodeInfoCompat_(System.IntPtr,System.IntPtr,System.IntPtr,System.IntPtr,System.IntPtr)' in assembly: 'Xamarin.AndroidX.RecyclerView.dll' ---> Mono.Cecil.ResolutionException: Failed to resolve AndroidX.Core.View.Accessibiity.AccessibilityNodeInfoCompat

Solution

I encountered this same problem after updating Visual Studio to 16.9.2 and updating the Android SDK.

The simple solution was to update the 'Xamarin.AndroidX.RecyclerView' Nuget package in the package manager. I Updated to the latest version (v1.1.0.8).
