Android JSON communication

We are developing an Android app. For the first part of this project we need to set up a login screen that will interact with our JSON/REST service. The JSON service will only return a single name/value pair indicating whether the username/password combo was correct. ## Deliverables The purpose of this project is to implement JSON communication in an Android app in the form of a login screen. **Requirements:** - Create 2 screens, the login screen and the logged in screen. - On login button press will post the username and password to a JSON/REST service. - If the service returns that the username/password is incorrect, display a message and stay on the login screen. - If the service returns that the username/password is correct, go to the logged in screen. If the remember me checkbox is checked then save the username in the shared preferences. - On the logged in screen when the log out button is pressed return to the login screen **Screens:** Login Screen - Show two labeled text fields, one for the username and one for the password. - Show a checkbox to remember the username - Show a login button Logged In Screen - Show a textview that says logged in - Show a log out button that will return to the login screen
