Design Implementation

Creating Login Functionality

Initially, I created a public method inside of the ‘MainActivity’ class that sets the value of the boolean variable ‘loggedIn’. Then I would call that method from the ‘LoginActivity; class to change the value of ‘loggedIn’. However, this did not function as I had expected. The ‘LoginActivity’ would refresh when the ‘login’ button was pressed despite a correct email and password being entered.

MainActivity:

LoginActivity:

Recognising the fundamental flaws of my original plan to track if a user is logged in, I decided to change tactics and use a shared preference instead. I created a new class called ‘LoginUtils’; this class contains the setter and getter for the login status. I added the necessary lines of code in the ‘MainActivity’ class and ‘LoginActivity’ class for this to function correctly.

A benefit of using shared preferences is that even after closing the application the user will still be registered as logged in.
