I've been able to run this on Android 9+ before. Can you clone the repository and run the example app if it works on the Android 9+ devices/emulators you were using to see if it works?

Thanks for the reply! Just one question, do i need to make secure http api calls for this plugin to work ?

[MaikuB]

Can you be more specific about what you mean here? Are you referring to http token and auth endpoints or API calls that you would make after being authorised?

Also what about the response to my question on the previous post I made?

My issue here was that the redirect URL did not end with oauthredirect

Closing due to lack of further response from the original poster. Note that I've read keycloak requires extra setup on more recent versions of Android. Another poster has posted their solution in https://github.com/MaikuB/flutter_appauth/issues/92 that you may want to try out. This is specific to keycloak and not to do with this plugin
