Describe your Issue:

Hi, in March I reported this error (#504), supposedly I have updated the libraries to the latest version and the error still exists.

There hadn't been a new version of this package released since the fix was committed. We've released a new version that should have the fix:

https://www.nuget.org/packages/Xamarin.AndroidX.Activity/1.4.0.3

@moljac @jpobst this problem still exists, but with ActivityResultContracts.GetContent (and like even more, which I didn't test)

public class MyGetContent : AndroidX.Activity.Result.Contract.ActivityResultContracts.GetContent
{
    public override Intent CreateIntent(Context context, Java.Lang.Object input)
    {
        return base.CreateIntent(context, input);
    }
}

name clash: createIntent(Context,Object) in MyGetContent and createIntent(Context,String) in ActivityResultContract have the same erasure, yet neither overrides the other public android.content.Intent createIntent (android.content.Context p0, java.lang.Object p1)

Should I open a new issue for it?

Also, is it possible to use the correct types for the Contract classes? E.g. GetContent should take a string when using ActivityResultLauncher.launch() and return a Uri in the OnActivityResult callback. I guess using generics isn't as easy in bindings...
