[kerberosargos]

Hello after update Xamarin.Android bindings for AndroidX package from 1.3.0.1 to 1.4.0 it gives error as following in build Android Solution time. There is no problem in version 1.3.0.1

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

I have same issue

Same here

I have same issue - VS 16.10.3, XF 5.0

Reverting package updates to Xamarin.Google.Android.Material from 1.4 -> 1.3.0.1 seems to have fixed this error for me. Your mileage may vary, but you may be able to maintain other version 1.4 references with the aforementioned package left behind at 1.3.0.1.

I am also using VS 16.10.3 with Xamarin.Forms 5.0.0.2083 (r4)

My case was error started from the change the deprecated AndroidX.AppCompat to new package.
Firstly, I removed 'Xamarin.AndroidX.AppCompat.Resources 1.x.x', and Re-Installed the new package: Xamarin.AndroidX.AppCompat.AppCompatResources v1.3.0.
On panic, Ahoke-cr 's solution (above) was working perfectly.

Downgrade 'Xamarin.Google.Android.Material' from 1.4 -> 1.3.0.1.
Thanks..

[nickpeppers]

Still an issue in 1.4.0.1 as well

[henda79]

I had this issue too but I never had the Xamarin.Google.Android.Material package installed. Anyway, I installed version 1.3.0.1 and it compiled ?!?

[MagicAndre1981]

Still an issue in 1.4.0.1 as well

the .1 only adds .net6-android as target and changed nothing else.

[Orgbrat]

This is still an issue even with all the AndroidX latest updates. Reverting package updates to Xamarin.Google.Android.Material from 1.4.0.1 -> 1.3.0.1 seems to have fixed this error for me.

I have the same issue.

Same true for TabbedPageRenderer -

TabbedPageRenderer is not abstract and does not override abstract method onNavigationItemSelected(MenuItem) in OnItemSelectedListener

[jpobst]

Looks like the issue is that Google added a new interface, added it to the existing interface, and moved the OnNavigationItemSelected method to it:

Material 1.3:

public interface IOnNavigationItemSelectedListener : IJavaObject, IDisposable, IJavaPeerable
{
  bool OnNavigationItemSelected(IMenuItem item);
}

Material 1.4:

[Obsolete("This class is obsoleted in this android platform")]
public interface IOnNavigationItemSelectedListener : NavigationBarView.IOnItemSelectedListener, IJavaObject, IDisposable, IJavaPeerable
{
}

public interface NavigationBarView.IOnItemSelectedListener : IJavaObject, IDisposable, IJavaPeerable
{
  bool OnNavigationItemSelected(IMenuItem p0);
}

This may (?) be a binary compatible change in Java, but it is not in C#.

I think XF/Maui will need to release a new version that is built against Material 1.4+, and specifies 1.4 as a minimum dependency.

That is, XF and the user app must be both compiled with 1.3 or earlier, or 1.4+. The issue now is that XF is compiled against 1.3, but the user app is compiled against (and shipping) 1.4.

The workaround for now is that users must continue to use Material 1.3 with the current version of XF.

[jpobst]

Maui has a PR they are working on to fix it there:
dotnet/maui#1927

Xamarin.Forms will need something similar, so I'm going to transfer this issue to that repo so they can track it.

[paulocarinhena]

Me too.

[MagicAndre1981]

Me too.

you need to wait until #14506 is merged and SR5 is out

[zipgenius]

This is still an issue in v. 1.4.0.2
The only workaround is to downgrade to 1.3.0.1

read my comment below, you need to wait until the mentioned RP is merged into XF and SR5 gets released.

[jfversluis]

Looks like this is resolved now, thanks!

Thank you, this helped me. Weird though, since We never installed this.

By using NavigationItemSelected on Xamarin.Forms 5.0.0.2196 and Xamarin.Google.Android.Material 1.3.0.1
I got : Error XA4204: Unable to resolve interface type 'Google.Android.Material.Navigation.NavigationBarView/IOnItemSelectedListener'. Are you missing an assembly reference? (XA4204)

Anybody knows how to solve this ?

5.0.0.2196 depends on Xamarin.Google.Android.Material in Version 1.4.x

[alexmartinezm]

Can you please ping me when this is fixed on Xamarin.Forms 5.0.0.2244? Thanks...

[Codelisk]

Still not fixed

[ClumsyPenguin]

Updating Xamarin.Forms to 5.0.0.2401 and then explicitly updated both Xamarin.Android to 1.7.0.2 and Xamarin.Google.Android.Material 1.5.0.2 fixed it for me
