An Android app developed as part of Aldoid Hackathon to demonstrate auto timeout of logged in user.
User is first presented with the LoginActivity. Once the user enters the corrcect username and password, appropriate data is
written into the SharedPreferences and the user is presented with UserActivity. A runnable is launched here that keeps
checking the user's logged in state.
User's loggedin state and metadata is stored in SharedPreferences.
The runnable thread is launched once the user logs in and is presented with the UserActivity. The thread activates every
second and checks if 20s have elapsed since the user's login. If yes, the user is logged out and presented with the
LoginActivity.
Once user logins on the LoginActivity, he is taken to the UserActivity. The user's login state and login time are stored
in SharedPreferences. The above mentioned runnable keeps track of the time elapsed and hence the user's session.
The LoginActicity is first launched when app starts. If user is already logged in and has a valid session,
the app proceeds to UserActivity, else the user is asked to login. The validity of session is checked using the data stored
in teh SharedPreferences.
