i have an android app and user have an online/offline state.it should change automatically after user Login/Logout.
i know must use of Custom Business Logic and event handler but i don’t know how to use it.
Custom Business Logic make an empty class and i don’t know where use of this class and how execute this event?
You do not have to use custom business logic for that. You can simply set a custom property in the user object and persist it to the backend.
yes but i want to reduce connection from app to server and use of server-side code.
what do this mean?
i want to reduce connection from app to server
i want to reduce api call.property change auto after user login.
Ok, if you want to use custom business logic, that’s fine. Start with the “getting started guide” so you understand how it works.
