So to confirm, this is affecting both iOS and the simulator?

On iOS, Google connect uses the native Google connect library - not a webview. On the simulator it uses a webview. So it is odd that these would have the same problems.

Can you confirm this? Can you also provide more details, and screenshots if possible, that show what you're seeing for each flow separately?

@shannah Please find below.

So this seems to be affecting Both IOS and Android. Am getting an error on the simulator with regards to jvafx
Below are the screenshots

1. IOS (version 18.6), Model name (iPhone14 plus)
   

2)Android (version 11), Nokia 7.2

3. Simulator

I just dusted off the old SignInDemo, and updated the project structure for Maven, then set up Google signin, built it for my device, and it worked ok.
I have published this demo here https://github.com/shannah/cn1-signin-demo

I suspect that you are using Oauth2 login on iOS and Android, which runs into this problem. You should be using native login, which isn't hard to set up. You just need to set up the app in firebase console, then download the GoogleService-Info.plist to to the ios/src/main/resources directory.

Similar on android.

I added instructions for that in the readme for that repo. (Disclaimer: I used chatgpt to generate some of the readme... let me know if you run into any errors, but it looks right to me).

For the simulator, you need to use Oauth2, unfortunately. I'm looking at that pathway now to see if there is anyway to get it working.

I played with getting Oauth working. There are a few different problems here:

1. Oauth login currently opens in a browser window, and the current implementation uses JavaFX, which is why you get that ClassNotFound.
2. If you set up the project to use a JVM with JavaFX, it will get past that, but the Google login page doesn't seem to work correctly in the JavaFX webview.
3. The cn1-apple-signin uses a native webview for the oauth login, so this could probably be adapted to work with Google. This will require a bit of work though. Not sure the ETA on that.

Thanks @shannah I have managed to get it working in Android. I had pretty much done all the steps in firebase but i see the only difference is that i was putting the google-services.json in native/android folder. When i moved it to the resources folder then the native Login was invoked as opposed as expected. My guese is we need to update the Codenameone Doc to reflect this.
