The ADT Bundle is a downloadable zip file that contains a special version of Eclipse with the Android
Development Tools plug-in, the Android Virtual Device Manager, the SDK Manager and tools, as well
as the latest Android platform, and the latest Android system image for the Android emulator. All you
have to do to install this ADT Bundle is to create a new directory and unzip the file into it. You can
use a free tool such as 7-Zip to uncompress the file. After doing this, you can execute the new
ADT Integrated Development Environment by executing the eclipse.exe file located in the Eclipse
directory under the main bundle directory.

7-Zip can be downloaded at www.7-zip.org .

Android Development Tools Integrated Development Environment
(IDE) Overview
The Eclipse IDE consists of several important sections that I will discuss here. The important
sections are the Package Explorer window, the Source Code Area window, the Outline window, and
the Messages windows, including a window that outputs programmer-specified debug messages
that is called the LogCat window. There are other Messages windows available, but they are less
important and won't be covered in this section.

Package Explorer
When you start on a new Android programming project, you will create a new package for it. In Eclipse,
there is a window called Package Explorer, located by default on the left-hand side. This window lists
all the Android packages located in the current work space. For example, Figure 1-5 lists packages
such as “AndroidHelloWorld,” “AndroidHelloWorldTest,” and “ApiDemos.”
