You have no control over the application and/or activity life cycle. This will make is very hard to determine when the user 'exits' the app.
I would do this: 1. Consider an explicit 'log-out' option for your users. 2. Add a time-out to your login-sessions. Refresh the session (time- out) when the user interacts with your app/server. But when the user hasn't interacted with your app/server for a given amount of time, the user's session will have had a time-out and this then would require the user to login again.
