[keycloak-user] Implementing Keycloak in Android app

Hi all, I have implemented Keycloak in my Tomcat server (via Keycloak Spring Adapter). Now, I am programming an Android App to communicate it with my server, but I have not found any information about how to manage the login to a server with Android. Has anyone implemented Keycloak with Android? Any ideas on how to approach this problem?? Thank you very much. -- Raquel Júdez.
