Book Description

Develop production-ready applications for iOS and Android using Xamarin

In Detail

Developing a mobile application for just one platform is becoming a thing of the past. Companies expect their apps to be supported on both iOS and Android, while leveraging the best native features on both. Xamarin's tools help ease this problem by giving developers a single toolset to target both platforms.

This book is a step-by-step guide to building real-world applications for iOS and Android. The book walks you through building a chat application, complete with a backend web service and native features such as GPS location, camera, and push notifications. Additionally, you'll learn how to use external libraries with Xamarin and Xamarin.Forms to create shared user interfaces and make app-store-ready applications. This second edition has been updated with new screenshots and detailed steps to provide you with a holistic overview of the new features incorporated in Xamarin 3. By the end of the book, you will have gained expertise to build on the concepts learned and effectively develop a market-ready cross-platform application.
