Contents UX Principles and Android OS Considerations Android Design Patterns and Antipatterns This book is about what works: design patterns. Design patterns in this book build on the official Google Android design guidelines by communicating best practices while addressing the complexities involved in real design problems. The official Android guidelines (available at http://developer.android.com/design/get-started/ui-overview.html) form the foundation; this book shows you how to bring these guidelines to life as complete solutions to real-world design challenges . With this chapter, I am laying the foundation for the 58 patterns (and 12 antipatterns) in the book by providing a case study of an app that could benefit from a more refined design—the AutoTrader app. The appropriate patterns are referenced in each section of this chapter; feel free to flip to the relevant pages to explore design solutions in more detail
