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 some of 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, the ADT plug-in provides the following features:

• The Android Project Wizard, which generates all the required project files

• Android-specific resource editors, including a Graphical Layout editor for designing Android application user interfaces

• The Android SDK Manager

• The Android Virtual Devices (AVD) Manager
