Teach Yourself Android Application Development in 24 Hours

While we specifically targeted Android SDK Version 2.1 in this book, many of the examples were tested on handsets running a variety of Android SDK versions. The Android SDK is updated very frequently (every few months). We kept this in mind when choosing which features of the SDK to highlight to ensure maximum forward and backward compatibility.

Teach Yourself Android Application Development in 24 Hours
When necessary, we point out areas where the Android SDK version affects
the features and functionality available to the developer. This book is written in a beginner’s tutorial style. If you’re looking for an exhaustive reference on Android development, with cookbook-style code examples and a more thorough examination of all the features of the Android platform, we recommend our other, more
advanced Android book, Android Wireless Application Development, which is part of the Addison-Wesley Developer’s Library series.
