Xamarin Android Project failed in target "_LinkAssembliesShrink"

[mczhao1977]

• ConfuserEx Version:1.5.0+b5197549e4
• Target Framework:.NET Standard 2.0 (Xamarin Android)
• Operating System:Win10

Steps to Reproduce:

I add one target in my csproj file to call ConfuserEx CLI to obfuscate the code after assembly built. The ConfuserEx successfully processed the assembly but the subsequence target _LinkAssembliesShrink failed with following error: XALNK7000: Mono.Linker.MarkException: Error processing method: 'System.Void demo.Pages.TestingPage::_B7m7Lms8Dbak5MgE0S8fg8CIYJuA()' in assembly: 'demo.dll' ---> Mono.Cecil.ResolutionException: Failed to resolve System.Void demo.Pages.TestingPage::skPreview_PaintSurface(System.Object,SkiaSharp.Views.Forms.SKPaintSurfaceEventArgs) at Mono.Linker.Steps.MarkStep.HandleUnresolvedMethod(MethodReference reference) at Mono.Linker.Steps.MarkStep.MarkMethod(MethodReference reference) at Mono.Linker.Steps.MarkStep.MarkInstruction(Instruction instruction) at Mono.Linker.Steps.MarkStep.MarkMethodBody(MethodBody body) at Mono.Linker.Steps.MarkStep.ProcessMethod(MethodDefinition method) at Mono.Linker.Steps.MarkStep.ProcessQueue() --- End of inner exception stack trace --- at Mono.Linker.Steps.MarkStep.ProcessQueue() at Mono.Linker.Steps.MarkStep.ProcessPrimaryQueue() at Mono.Linker.Steps.MarkStep.Process() at Mono.Linker.Steps.MarkStep.Process(LinkContext context) at MonoDroid.Tuner.MonoDroidMarkStep.Process(LinkContext context) at Mono.Linker.Pipeline.ProcessStep(LinkContext context, IStep step) at Mono.Linker.Pipeline.Process(LinkContext context) at MonoDroid.Tuner.Linker.Process(LinkerOptions options, ILogger logger, LinkContext& context) at Xamarin.Android.Tasks.LinkAssemblies.Execute(DirectoryAssemblyResolver res) at Xamarin.Android.Tasks.LinkAssemblies.RunTask()

It seems linking process can't find some obfuscated method. So what's the best point to insert the obfuscation target?

Thanks

This is very difficult to say, based on the information provided. I'm guessing some protection is active that doesn't work well with the Android target. What are the obfuscation settings used in this case?
