Xamarin Android 10 Install APK - No Activity found to handle Intent

I want to install a 3rd party app from the filesystem from my xamarin android app. The code I used successfully before Android 10 was pretty straightforward and easy.

            Intent intent = new Intent(Intent.ActionView);
            Uri data = Uri.FromFile(file);

            intent.SetDataAndType(data, "application/vnd.android.package-archive");

            context.StartActivity(intent);

This code does not work on Android 10 because of ACTION_VIEW and ACTION_INSTALL_PACKAGE were deprecated in Android 10. Looks like we now need to use the PackageInstaller API.

I tried to write a method using the PackageInstaller API. Unfortunately it doesn't work.

Code with PackageInstaller API

 public static void InstallPackageAndroidQAndAbove(Context context, string filePath, string packageName)
    {

        var packageInstaller = context.PackageManager.PackageInstaller;
        var sessionParams = new PackageInstaller.SessionParams(PackageInstallMode.FullInstall);
        sessionParams.SetAppPackageName(packageName);
        int sessionId = packageInstaller.CreateSession(sessionParams);
        var session = packageInstaller.OpenSession(sessionId);

        var input = new FileStream(filePath, FileMode.Open, FileAccess.Read);
        var output = session.OpenWrite(packageName, 0, -1);

        input.CopyTo(output);

        output.Close();
        input.Close();
        input.Dispose();

        session.Fsync(output);

        var pendingIntent = PendingIntent.GetBroadcast(context, sessionId, new Intent(Intent.ActionInstallPackage), 0);
        session.Commit(pendingIntent.IntentSender);

    }

An exception "Unrecognized stream" occurs during the call.

I hope someone can help me.

Thank you very much in advance.
