Description
Android Wireless Application Development has earned a reputation as the most useful real-world guide to building robust, commercial-grade Android apps. Now, authors Lauren Darcey and Shane Conder have systematically revised and updated this guide for the latest Android SDK and tools updates. To accommodate their extensive new coverage, they've split the book into two leaner, cleaner volumes. This Volume II focuses on advanced techniques for the entire app development cycle, including design, coding, testing, debugging, and distribution. Darcey and Conder cover hot topics ranging from tablet development to protecting against piracy and demonstrate advanced techniques for everything from data integration and UI development to in-app billing.
Every chapter has been thoroughly updated to reflect the latest SDKs, tools, and devices. The sample code has been completely overhauled and is available for download on a companion website. Drawing on decades of in-the-trenches experience as professional mobile developers, the authors also provide even more tips and best practices for highly efficient development. This new edition covers
Advanced app design with async processing, services, SQLite databases, content providers, intents, and notifications
Sophisticated UI development, including input gathering via gestures and voice recognition
Developing accessible and internationalized mobile apps
Maximizing integrated search, cloud-based services, and other exclusive Android features
Leveraging Android 4.0 APIs for networking, web, location services, the camera, telephony, and hardware sensors
Building richer apps with 2D/3D graphics (OpenGL ES and RenderScript), animation, and the Android NDK
Tracking app usage patterns with Google Analytics
Streamlining testing with the Android Debug Bridge
This book is an indispensable resource for every intermediate- to advanced-level Java developer now participating in Android development and for every seasoned mobile developer who wants to take full advantage of the newest Android platform and hardware.

Persons
Lauren Darcey is responsible for the technical leadership and direction of a small software company specializing in mobile technologies, including Android, Apple iOS, Blackberry, Palm Pre, BREW, J2ME, and consulting services. With more than two decades of experience in professional software production, Lauren is a recognized authority in application architecture and the development of commercial-grade mobile applications. Lauren received a B.S. in computer science from the University of California, Santa Cruz.
She spends her free time traveling the world with her geeky mobile-minded husband and daughter. She is an avid nature photographer. Her work has been published in books and newspapers around the world. In South Africa, she dove with 4-meter-long great white sharks and got stuck between a herd of rampaging hippopotami and an irritated bull elephant. She's been attacked by monkeys in Japan, gotten stuck in a ravine with two hungry lions in Kenya, gotten thirsty in Egypt, narrowly avoided a coup d'etat in Thailand, geocached her way through the Swiss Alps, drank her way through the beer halls of Germany, slept in the crumbling castles of Europe, and had her tongue stuck to an iceberg in Iceland (while being watched by a herd of suspicious wild reindeer).
Shane Conder has extensive development experience and has focused his attention on mobile and embedded development for the past decade. He has designed and developed many commercial applications for Android, iOS, BREW, Blackberry, J2ME, Palm, and Windows Mobile--some of which have been installed on millions of phones worldwide. Shane has written extensively about the mobile industry and evaluated mobile development platforms on his tech blogs. He is well-known within the blogosphere. Shane received a B.S. in computer science from the University of California. A self-admitted gadget freak, Shane always has the latest smartphone, tablet, or other mobile device. He can often be found fiddling with the latest technologies, such as cloud services and mobile platforms, and other exciting, state-of-the-art technologies that activate the creative part of his brain. He is a very hands-on geek dad. He also enjoys traveling the world with his geeky wife, even if she did make him dive with 4-meter-long great white sharks and almost got him eaten by a lion in Kenya. He admits that he has to take at least two phones with him when backpacking--even though there is no coverage--and that he snickered and whipped out his Android phone to take a picture when Laurie got her tongue stuck to that iceberg in Iceland, and that he is catching on that he should be writing his own bio.
The authors have also published several other Android books, including Android Wireless Application Development, Android Wireless Application Development Volume I: Android Essentials, Sams Teach Yourself Android Application Development, Learning Android Application Programming for the Kindle Fire, and the mini-book Introducing Android Development with Ice Cream Sandwich. Lauren and Shane have also published numerous articles on mobile software development for magazines, technical journals, and online publishers of educational content. You can find dozens of samples of their work in Linux User and Developer, Smart Developer magazine (Linux New Media), developer.com, Network World, Envato (MobileTuts+ and CodeCanyon), and InformIT, among others. They also publish articles of interest to their readers at their own Android website, http://androidbook.blogspot.com.You can find a full list of the authors' publications at http://goo.gl/f0Vlj.
