Familiarizing Yourself with Eclipse

Let's begin by writing a simple Android "Hello, World" application that displays a line of text to the user. As you do so, you will also be taking a tour through the Eclipse environment. Specifically, you will learn about the features offered by the Android Development Tools (ADT) plug-in for Eclipse. The ADT plug-in provides functionality for developing, compiling, packaging, and deploying Android applications. Specifically, it provides the following:

► The Android project wizard, which generates all the required project files

► Android-specific resource editors

► The Android SDK and AVD (Android Virtual Devices) Manager

The Eclipse DDMS perspective for monitoring and debugging Android applications

Integration with Android LogCat logging

Automated builds and application deployment to Android emulators and handsets

Application packaging and code signing tools for release deployment

Installing the Android SDK and Tools

You will find all the details of how to install and configure your computer for Android application development in Appendix A, "Configuring Your Android Development Environment." You will need to install and configure Eclipse, the Android SDK, and the ADT plug-in for Eclipse. You may also need to install the USB drivers for any Android handsets you will be using for development.

Now let's take some of these features for a spin.
