Learn the bare essentials needed to begin developing cross-platform, mobile apps using Xamarin.Forms. Apps can be easily deployed to Google Play or to the Apple App Store. You will gain insight on architecture and how to arrange your app´s design, where to begin developing, what pitfalls exist, and how to avoid them. Also covered are expected new features in Xamarin.Forms 3.0, so you may be prepared ahead of time for what the next release brings. Xamarin.Forms Essentials provides a brief history of Xamarin as a company, including how their product has become one of the most-used, cross-platform technologies for enterprise applications and app development across the world. Examples in the book are built around a real-life example that is an actual app in Google Play and in the Apple App Store, and has thousands of downloads between iOS and Android. You will learn how an application is set up from scratch, and you will benefit from the author´s hard-won experience and tips in addressing various development challenges. What You´ll Learn Create cross-platform user interfaces from one code base for both iOS and Android See how a commercial application is built and then deployed for sale in the app stores Integrate your Xamarin.Forms applications with third-party, RESTful APIs Arrange application architecture to avoid pitfalls and optimize your design Get a heads-up on new features released as part of Xamarin.Forms 3.0 Choose appropriately between Xamarin.Forms and traditional Xamarin, depending upon your application needs and its goals Who This Book Is For Mobile app developers who are producing software for multiple platforms, including Google Android and Apple iOS. Readers should be familiar with Visual Studio either on Mac OS X or Windows, and have a working knowledge of C#.
The Xamarin tool suite, Xamarin.Android and Xamarin.iOS, is a bridge from .NET into the world of native mobile development. These tools give C sharp developers a direct line into native Android and iOS development, allowing them to build business apps for the Google Play and iTunes app stores. This book helps a developer navigate Android and iOS architecture using .NET. Mobile development makes frequent use of traditional patterns such as MVC, MVVM, Delegates, and Singleton. Pattern-savvy readers will find familiar .NET foundations here with logical bridges into mobile platform-specific implementations. Newcomers to design patterns will find a mobile pattern guidebook. The iOS UI must still be written in Xcode. The Android UI rests on Activities. How are all of these built on a variation of the familiar MVC pattern? The reader will learn about mobile data binding and decoupling of UI and back-end logic for cross-platform code reuse. Application lifecycles on native platforms are unique as mobile and tablet apps spawn, live, pause, and die. The reader will learn how code must respond to changes in state and manage data transfer between views. Web services are the mainstay of mobile data and this is a primer for cross-platform client/service construction. It also explores background data-loading techniques and offline access using local data structures: blueprints for the mobile data layer. This comprehensive recipe and reference book addresses one of the most important and vexing problems in the software industry today: How do we effectively design and develop cross-platform native mobile applications?
