You're missing the namespace import (you could fully qualify it like below) public class WebAuthenticatorCallbackActivity : global::Microsoft.Maui.Authentication.WebAuthenticatorCallbackActivity

@Redth thanks, I tried that but it's still not working with the same errors. What would be the namespace for the class attributes?

I have the same issue

Hi @PhilippRoessner,

I found the solution. You have to add

Exported = true in Activity attribute.

[Activity(NoHistory = true, LaunchMode = LaunchMode.SingleTop, Exported = true)]
[IntentFilter(new[] { Intent.ActionView }, Categories = new[] { Intent.CategoryDefault, Intent.CategoryBrowsable }, DataScheme = "yourscheme")]
public class WebAuthenticationCallbackActivity : WebAuthenticatorCallbackActivity
{
}```

@shurkin YES! Thanks, it's working now :-)

I still get this error using RC2. I just switched to copying the strings as literals

[Joren-Thijs-KasparSolutions]

That being said it's still not working for me. i still get an error when trying to login:

System.InvalidOperationException: You must subclass the `WebAuthenticatorCallbackActivity` and create an IntentFilter for it which matches your `callbackUrl`.
   at Microsoft.Maui.Authentication.WebAuthenticatorImplementation.AuthenticateAsync(WebAuthenticatorOptions webAuthenticatorOptions) in D:\a\_work\1\s\src\Essentials\src\WebAuthenticator\WebAuthenticator.android.cs:line 63
   at App.Features.Login.WebAuthenticatorBrowser.InvokeAsync(BrowserOptions options, CancellationToken cancellationToken)

I don't understand do I need to link the activity somewhere on startup? why can I not find any docs on this?
