Xamarin Cross-platform Application Development

Book Description

Develop production-ready applications for iOS and Android using Xamarin

Overview

• Write native iOS and Android applications with Xamarin
• Add native functionality to your apps such as push notifications, camera, and GPS location
• Learn various strategies for cross-platform development

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, whilst leveraging the best native features of both. Xamarin’s tools help solve this requirement by giving developers a single toolset to target both platforms.

“Xamarin Cross-platform Application Development” is a step-by-step guide for building professional 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.

This book begins with iOS and Android application fundamentals, then moves on to sharing code, and eventually digs deeper into native functionality. By the end of the book, readers will have successfully built a cross-platform application ready for submitting to app stores. You will gain an in-depth knowledge about the concepts of building cross platform applications.

“Xamarin Cross-platform Application Development” also covers native iOS and Android APIs, unit testing, building a real web service with Windows Azure, push notifications, interacting with the camera and GPS, leveraging Java and Objective-C libraries, and finally app store submission. Towards the end of the book you will feel confident in developing your own Xamarin applications.

“Xamarin Cross-platform Application Development” will teach you everything you need to know to develop an end-to-end, cross-platform solution with Xamarin.

What you will learn from this book

• Familiarize yourself with Apple’s MVC design pattern
• Understand the Android activity lifecycle
