In this section we take a brief look at persistence within an Android app (via SQLite) but focus mainly on how the Android OS implements multithreading and deals with running tasks in the background. We also investigate the different approaches available to the developer for making http calls and API requests.

Here we take a quick look at JSON and how it can be used as a format for transferring data to and from an Android app.

This lab continues our Case Study CoffeeMate but with a major refactoring of the UI (using a Navigation Drawer) and a more detailed look at the use of Fragments and persistence (through an SQLite Database) in an Android App.
