Smartphones and other touch-based mobile devices are all the rage these days. Their popularity
is largely due to their ability to run apps. Although the iPhone and iPad with their growing
collection of Objective-C-based apps are the leaders of the pack, Android-based smartphones
with their growing collection of Java-based apps are proving to be a strong competitor.
Not only are many iPhone/iPad developers making money by selling their apps, many
Android developers are also making money by selling similar apps. According to tech websites
such as The Register (www.theregister.co.uk/), some Android developers are making lots of
In today’s tough economic climate, perhaps you would like to try your hand at becoming an
Android developer and make some money. If you have good ideas, perseverance, and some
artistic talent (or perhaps know some talented individuals), you are already part of the way
toward achieving this goal.
Most importantly, you will need to possess a solid understanding of the Java language and
foundational application programming interfaces (APIs) before jumping into Android. After all,
Android apps are written in Java and interact with many of the standard Java APIs (such as
threading and input/output APIs).
I wrote Learn Java for Android Development to give you a solid Java foundation that you can
later extend with knowledge of Android architecture, API, and tool specifics. This book will give
you a strong grasp of the Java language and many important APIs that are fundamental to
Android apps and other Java applications. It will also introduce you to key development tools.
Learn Java for Android Development is organized into ten chapters and one appendix. Each
chapter focuses on a collection of related topics and presents a set of exercises that you should
complete to get the most benefit from the chapter’s content. The appendix provides the solutions
to each chapter’s exercises.
