Android Recipes, Second Edition is primarily a resource for experienced Android developers. It largely presents recipes for accomplishing various tasks. For example, Chapter 2 presents a recipe on working with the WindowManager class to customize window attributes (e.g., present a custom title and hide or show the action bar).
Realizing that not everyone is an experienced Android developer, the first chapter of this book, "Getting Started with Android", provides an introduction to Android app architecture (in terms of components [e.g., activities]), resources, the manifest, and the app package (APK). It then discusses how to install the necessary software for developing an Android app and discusses the creation and execution of a sophisticated Univerter app in command-line and Eclipse IDE contexts -- Appendix D presents and walks the reader through the app's source code and resources. Univerter gives the beginner a chance to explore a significant Android app that could be extended (as demonstrated elsewhere in the book) and even published to Google Play.
Some beginners might not care for the rapid approach that Chapter 1 takes to introduce Android app development. However, many of the basics are covered in this chapter.
By way of appendixes, this book also presents app design guidelines that can help the developer create a more robust app, and also presents detailed coverage of SDK and platform tools.
Despite the advanced material in the book (e.g., Android NDK and Renderscript), the content has been written to aid anyone from a beginner through advanced developer.
