My app hitting every API method with authentication token of combination of username and password. While app running if user change credential from web then from app unable to hit API method . I just want if the Authentication fails on any API call, then jump to the LOGIN screen. There is one alternative solution for this is that, every API call check response status and if authentication fail then jump to the login screen. But I think it is very lengthy process to handle this. So my question is there is any smart solution for this ? Please let me know.
