Building Your First App

Dependencies and prerequisites

Welcome to Android application development!

This class teaches you how to build your first Android app. You’ll learn how to create an Android project and run a debuggable version of the app. You'll also learn some fundamentals of Android app design, including how to build a simple user interface and handle user input.

Before you start this class, be sure that you have your development environment set up. You need to:

  1. Download the Android SDK Starter Package.
  2. Install the ADT plugin for Eclipse (if you’ll use the Eclipse IDE).
  3. Download the latest SDK tools and platforms using the SDK Manager.

If you haven't already done this setup, read Installing the SDK. Once you've finished the setup, you're ready to begin this class.

This class uses a tutorial format that incrementally builds a small Android app in order to teach you some fundamental concepts about Android development, so it's important that you follow each step.
