ShellItemRenderer.java - Error when building Android Solution

Andrew 156

Hi
When building the solution (tried both Xamarin forms 4.8 and 5) i keep getting the folllowing errors. I have deleted bin and obj directories but the issue continues

Error error: ShellItemRenderer is not abstract and does not override abstract method onNavigationItemSelected(MenuItem) in OnItemSelectedListener
public class ShellItemRenderer My.Android c:\ShellItemRenderer.java 4

Error error: TabbedPageRenderer is not abstract and does not override abstract method onNavigationItemSelected(MenuItem) in OnItemSelectedListener
public class TabbedPageRenderer My.Android C:\TabbedPageRenderer.java 4

At a bit of a loss now what to do next - error keeps coming back

Reverting package updates to Xamarin.Google.Android.Material from 1.4 -> 1.3.0.1 seems to have fixed this error for me

seems like it's a Xamarin.Google.Android.Material update issue https://github.com/xamarin/AndroidX/issues/335
