[severity:It bothers me. A fix would be nice] DotNet-8.0-Android : In-App Update Build Failing

Using Nuget package Xamarin.Google.Android.Play.Core.AppUpdate (Version: 2.1.0.9) Build Is Failing with this error: 1. Home_AppUpdateInstallUpdateListner is not abstract and does not override abstract method onStateUpdate(InstallState) in StateUpdatedListener public class Home_AppUpdateInstallUpdateListner

2. name clash: onStateUpdate(Object) in Home_AppUpdateInstallUpdateListner and onStateUpdate(InstallState) in StateUpdatedListener have the same erasure, yet neither overrides the other public void onStateUpdate (java.lang.Object p0)

Code I'm Using : FileName : Home.cs

using Xamarin.Google.Android.Play.Core.AppUpdate;
using Xamarin.Google.Android.Play.Core.AppUpdate.Install;
using Xamarin.Google.Android.Play.Core.AppUpdate.Install.Model;

public IAppUpdateManager? AppUpdateManager;
private AppUpdateInstallUpdateListner? MyInstallUpdateListner;
public const int AppUpdateTypeSupported = AppUpdateType.Flexible;

protected override void OnCreate(Bundle? savedInstanceState)
{
     base. OnCreate(savedInstanceState);
     HomeLayout = BindingHome.Inflate(LayoutInflater);
     SetContentView(HomeLayout.Root);
     try
     {
         OneSignal.Notifications.RequestPermissionAsync(true);
         App.SetUserId();
         AppUpdateManager = AppUpdateManagerFactory.Create(this);
         MyInstallUpdateListner = new AppUpdateInstallUpdateListner(AppUpdateManager);
         AppUpdateManager.RegisterListener(MyInstallUpdateListner);
         var AppUpdateInfoTask = AppUpdateManager.GetAppUpdateInfo();
         AppUpdateInfoTask.AddOnSuccessListener(new InAppUpdateSuccessListener(AppUpdateManager, this));
     } 
     catch (Exception Ex) { App.ReportError(Ex); }
 }

public class InAppUpdateSuccessListener(IAppUpdateManager? AppUpdateManager, Activity? Home) : Java.Lang.Object, IOnSuccessListener
{
    private readonly IAppUpdateManager? AppUpdateManager = AppUpdateManager;
    private readonly Activity? Home = Home;

public void OnSuccess(Java.Lang.Object result)
    {
        if (result is not AppUpdateInfo EInfo)
        {
            return;
        }

if (EInfo.InstallStatus() == InstallStatus.Downloaded)
        {
            AppUpdateManager?. CompleteUpdate();
            return;
        }

int IAvailability = EInfo.UpdateAvailability();
        if ((IAvailability.Equals(UpdateAvailability.UpdateAvailable) ||
            IAvailability.Equals(UpdateAvailability.DeveloperTriggeredUpdateInProgress)) &&
            EInfo.IsUpdateTypeAllowed(AppUpdateType.Immediate))
        {
            AppUpdateOptions? Options = AppUpdateOptions.NewBuilder(AppUpdateTypeSupported). Build();
            AppUpdateManager?. StartUpdateFlow(EInfo, Home, Options);
        }
    }
}

public class AppUpdateInstallUpdateListner(IAppUpdateManager? AppUpdateManager) : Java.Lang.Object, IInstallStateUpdatedListener
{
    public IAppUpdateManager? AppUpdateManager = AppUpdateManager;

public void OnStateUpdate(Java.Lang.Object p0)
    {

if (p0 is not InstallState state)
        {
            return;
        }

if (state. InstallStatus() == InstallStatus.Downloaded)
        {
            AppUpdateManager?. CompleteUpdate();
        }
    }
}

Hi

There is a problem with Binding generics in C#. Unfortunately the API you want to use has generics.
To work around this you can take a look at something we did for Asset Delivery https://github.com/xamarin/GooglePlayServicesComponents/blob/main/source/com.google.android.play/asset.delivery.extensions/extensions-aar/src/main/java/xamarin/google/android/play/core/assetpacks/AssetPackStateUpdateListenerWrapper.java.

The idea is you write a Wrapper class which exposes a non generic API to C#. You can then add this java file to your project with a AndroidJavaSource build action. It will bind it just before the build and your new API should show up.

The source code I have linked to should give you an idea of what to do.

I put together a sample for you

package xamarin.google.android.play.core.install;

import com.google.android.play.core.install.InstallStateUpdatedListener;
import com.google.android.play.core.install.InstallState;

public class InstallStateUpdatedListenerWrapper {
    private InstallStateUpdatedListener installStateUpdatedListener = state -> {
        onStateUpdate (state);
    };

    void onStateUpdate(InstallState state)
    {
        if (stateUpdateListener != null)
            stateUpdateListener.OnStateUpdate(state);
    }

    public InstallStateUpdatedListener GetListener()
    {
        return installStateUpdatedListener;
    }

    public interface InstallStateListener {
        /**
         * Called when an the State is Updated
         *
         * @param state The Install Session State.
         */
        abstract void OnStateUpdate (InstallState state);
    }

    private InstallStateListener stateUpdateListener = null;

    public void setStateUpdateListener (InstallStateListener listener)
    {
        stateUpdateListener = listener;
    }
}

and the C# side will be

var installListener = new InstallStateUpdatedListenerWrapper();
installListener.StateUpdate += (sender, args) => {
   // do stuff.
};

I did however have to add this to my csproj

  <Target Name="_Foo" AfterTargets="ResolveAndroidTooling" BeforeTargets="_CompileBindingJava">
  <ItemGroup>
    <_ReferenceJavaLibs Include="$(AndroidSdkBuildToolsPath)core-lambda-stubs.jar" />
  </ItemGroup>
