60 CHAPTER 2: Configuring Your Android App Development System
apply to Android 4.x and 5.x OS versions alike. For this reason you do not have to worry about the
content in this book becoming obsolete, especially because I cover the entire new media content
development work process, and not just Android programming alone.
Summary
In this second chapter, you made sure that your Eclipse ADTs installation that you downloaded
and put together in Chapter 1 is fully updated, and properly configured for the Android application
development that you will be undertaking throughout the rest of this book.
Next, you learned about hardware product emulators, called Android Virtual Devices, also known as
AVDs, and you learned why these AVDs are important to understand and how to implement them, so
that you can utilize AVDs to accelerate your Android application development work process.
You created a Google Nexus One AVD by using Eclipse ADT’s predefined AHD definition for this
smartphone device and by doing this you learned all about a (second) Device Definitions tab within
the Android Virtual Device Manager dialog.
Then you got a little bit more advanced and created your own AHD device definition for the Neptune
Pine SmartWatch, so that you could create an AVD emulator for the Neptune Pine SmartWatch from
scratch. You accomplished this by going to the NeptunePine.com web site and finding the product
info page, which contains all of the product specifications, and created your own AHD definition
using the New Device button and dialog.
Finally, we took a few pages to go over what you will be learning about in the rest of this book,
so that you have a high-level overview of what I will cover as well as how many truly powerful
development capabilities the Android OS currently encompasses. As I mentioned, I am going to
attempt, within one single book title, to take my readers from an Absolute Beginner status to a solid
intermediate status.
In Chapter 3, you will start developing your first Android application, while at the same time learning
about the “lingo” of Android, and getting a high-level overview of how the Android ecosystem all fits
together, to allow developers to efficiently create Android applications.
