Hello, Android is divided into three parts. Roughly speaking, the book
progr esses from less advanced to more advanced topics, or from more
common to less common aspects of Android.
Several chapters share a common example: an Android S udoku game.
By gradually adding features to th e game, you’ll learn about many
aspects of Android programming in cluding user interfaces, multime-
dia, and the Android life cycle.
In Part I, we’ll start with an introduction to Android. This is where you’ll
learn how to install the Android emulator and how to use an int egrated
development envir onment (IDE) to write your first program. Then we’ll
intr oduce a few key concepts like the Android life cycle. Programming
in Android is a little different from what you’re probably used to, so
make sure you get these concepts before moving on.
Part II talks about Android’s user interface, two-dimensional graphics,
multimedia components, and simple data access. These features will be
used in most programs you write.
Part III digs deeper into the Android platform. Here y ou’ll learn about
connecting to the outside world, location-based services, the built-in
SQLite database, and three-dimensional graphics.
At the end of the book, you’ll find appendices that cover the dif
f
erences
between Android and Java Standard Edition (SE), how to create a wid-
get, and publishing your application.

To accommodate the new version, every page and example in this book
has been r eviewed and updated so it will work with 1.5. Most of the
changes were small but a few sections needed major revisions. If you’ve
