Chapter 1. The First App

Welcome! In this chapter, we won't waste any time in getting started with developing Android apps.

We will look at what is so great about Android, what Android and Java are exactly, how they work and complement each other, and what this means to us as future developers.

After this, we will spend a little time setting up our development environment and then get straight to building and deploying our first app.

By the end of this chapter, we will have done the following:

• Set up the Java Development Kit (JDK), part of the required Android development environment
• Installed Android Studio, the final part of our Android development environment
• Built our very first Android app
• Deployed an Android emulator
• Run our app on an Android emulator and a real device
