Xamarin: Cross-Platform Mobile Application Development

Overview of this book

Developing a mobile application for just one platform is becoming a thing of the past. Companies expect their apps to be supported on iOS, Android, and Windows Phone, while leveraging the best native features on all three platforms. The primary goal of this course is to equip you with the knowledge to successfully analyze, develop, and manage Xamarin cross-platform projects using the most efficient, robust, and scalable implementation patterns. Module 1 is a step-by-step guide to building real-world applications for iOS and Android. The module 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. Module 2 provide you recipes on how to create an architecture that will be maintainable, extendable, use Xamarin.Forms plugins to boost productivity. We start with a simple creation of a Xamarin.Forms solution, customize the style and behavior of views for each platform. Further on, we demonstrate the power of architecting a cross-platform solution. Next, you will utilize and access hardware features that vary from platform to platform with cross-platform techniques. In the last and the final Module, you will learn about essential tools to leverage the pattern and advanced implementation strategies. We'll show you the toolset for application lifecycle management to help you prepare the development pipeline to manage and see cross-platform projects through to public or private release. After the completion of this course, you will learn a path that will get you up and running with developing cross-platform mobile applications and help you become the go-to person when it comes to Xamarin. This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products: ?Xamarin Cross-platform Application Development - Second Edition by Jonathan Peppers ?Xamarin Cross-Platform Development Cookbook by George Taskos ?Mastering Cross-Platform Development with Xamarin by Can Bilgin

Chapter 9. Reusable UI Patterns

In this chapter, we will discuss strategies and patterns for reusing visual assets (that is, text and media resources) in cross platform projects. Furthermore, reusable assets will be iteratively explained from the localization perspective. Finally, some advanced software architectural topics about Model-View-Controller and Model-View-ViewModel patterns will be analyzed and demonstrated. This chapter is divided into the following sections:

  • Visual assets
  • Localization
  • Architectural patterns

Visual assets

We can classify any resource included in the project at compile time and used by the user interface as a visual asset. Visual assets can vary from simple text elements to media items (for example images, animations, videos, and so on) to be used for creating the visual elements of the user interface. Each Xamarin target platform provides different mechanisms to store and dispatch these assets.

On Android and iOS, resources and their localized representations...
