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.

In this Lab, you will be required to build the first version of our Donation Case Study App, called Donation.1.0. Here, we will add in a few UI widgets on a single layout and implement some basic event handling.
