Description

After updating from 2.4.3 to 2.4.4 or 2.5-preview, on building a Xamarin.Forms (v3.3.0.967583) project for Android, the linker throws an exception.

Expected Behavior

It should just build fine, like in version 2.4.3.

Actual Behavior

Error The "LinkAssemblies" task failed unexpectedly.
Mono.Linker.MarkException: Error processing method: 'System.Void FFImageLoading.Forms.Platform.CachedImageFastRenderer::Xamarin.Forms.Platform.Android.IVisualElementRenderer.add_LayoutChange(System.EventHandler`1<Android.Views.View/LayoutChangeEventArgs>)' in assembly: 'FFImageLoading.Forms.Platform.dll' ---> Mono.Cecil.ResolutionException: Failed to resolve System.Void Xamarin.Forms.Platform.Android.IVisualElementRenderer::add_LayoutChange(System.EventHandler`1<Android.Views.View/LayoutChangeEventArgs>)

Same behaviour with Xamarin.Forms 3.3.0.967583 and FFImageLoading 2.4.4.859

I had the same issue & a quick temporary fix is to downgrade the version used to a previous working one. For me, It was 2.4.3.840. Just unload your projects & directly edit the csproj files.

<ItemGroup> <PackageReference Include="Xamarin.FFImageLoading" Version="2.4.3.840" /> <PackageReference Include="Xamarin.FFImageLoading.Forms" Version="2.4.3.840" /> </ItemGroup>

Downgrading to 2.4.3.840 worked for me as well, I was using 2.4.4.859 and got the same error as OP.

Isn't this not recommended for Release?

I have the same problem with Xamarin Forms 3.6.0.220655 and FFImageLoading 2.4.4.859

Unhandled Exception:

System.TypeLoadException: Could not load list of method overrides due to Method not found: void Xamarin.Forms.Platform.Android.IVisualElementRenderer.add_LayoutChange(System.EventHandler`1)

here is my MainActivity.OnCreate :

    protected override void OnCreate(Bundle bundle)
    {
        TabLayoutResource = Resource.Layout.Tabbar;
        ToolbarResource = Resource.Layout.Toolbar;

        this.Window.AddFlags(WindowManagerFlags.Fullscreen);

        base.OnCreate(bundle);
        Plugin.CurrentActivity.CrossCurrentActivity.Current.Init(this, bundle);

        global::Xamarin.Forms.Forms.SetFlags("FastRenderers_Experimental");

        CachedImageRenderer.Init(true);

        var config = new FFImageLoading.Config.Configuration()
        {
            VerboseLogging = false,
            VerbosePerformanceLogging = false,
            VerboseMemoryCacheLogging = false,
            VerboseLoadingCancelledLogging = false,
            Logger = new CustomLogger(),
        };
        FFImageLoading.ImageService.Instance.Initialize(config);

        global::Xamarin.Forms.Forms.Init(this, bundle);

        AndroidAppLinks.Init(this);

        LoadApplication(new YApp());

        FirebasePushNotificationManager.ProcessIntent(this, Intent);
    }

everything looks allright, in fact the App was working untill I updated the xamarin Forms And Xamarin.Android NuGets
