Book excerpt: XamarinBuilding Your First Mobile App with C# .NET and Xamarin, Xamarin for beginnersThe entire world is now surrounded by billions and trillions of mobile Tech which is inevitable. The major share of the development of mobile apps is taken by the Google's Android, Apple's iOS, and Microsoft's Windows. Every new learner or newbie in Mobile Development Domain finds himself in the dilemma of choosing the platform to start with. They are actually looking for a platform to execute or implement the test apps on something different from what it is intended for.Xamarin is one of the solutions to it which actually is meant for cross-platform mobile app development where you can build Android, iOS, and Windows native application using a single codebase. This single platform is C#. The apps developed using Xamarin performs almost similar to the native Platform applications.Working of XamarinXamarin has entirely converted the Android and iOS SDK to C# to make it more familiar to the developers. One can easily use the same codebase for both the platforms without the hassle of remembering the syntax of different languages all the time. Besides, the User Interface(UI) remains almost same. It has to be separately built for both the platforms and then has to be bound by the common codebase.There are actually two ways for building the User Interface. First one is using the original native methods to build the UI. Another one incorporates the use of Xamarin.Forms. These forms can be used to build UI for different platforms all at once and have almost 100% code sharing if these are chosen over Native UI Technology.After doing all the UI work comes the most challenging phase which is connecting the UI to the codebase. This connection can again be implemented using two code sharing approaches which are:1.Shared Project2.Portable Class Libraries(PCL)Xamarin.FormsXamarin provides developers two ways to build a mobile app. Either by using Xamarin.iOS and Xamarin.Android(main approach) or by using Xamarin.Forms which is a framework for simple apps and prototypes. Xamarin.Forms, the Visual Studio Library facilitates for rapid prototyping or building apps with few platform-specific functionalities. This makes Xamarin.Forms, the best fit, for apps considering code sharing more significant than custom UI. The developer need not design for each platform individually. With Xamarin.Forms, a single interface would be shared across platforms. Apps with some parts of the UI created using Xamarin.Forms and rest using native UI Toolkit can also be built using this approach.What Is Xamarin.Forms?Xamarin.Forms is a cross-platform natively backed UI toolkit abstraction that allows developers to easily create user interfaces that can be shared across Android, iOS, Windows, and Windows Phone.PerformanceXamarin apps are fully native so in xamarin you can enjoy fully native performance with shared code.Xamarin.iOS and Xamarin.Android (Separate UI)For Xamarin.iOS and Xamarin.Android, you have shared code base in C# .This business logic is shared across platforms and UI is separate for all platforms. This is separate UI approach. Xamarin.ios and Xamarin.Android give you 100% API coverage with benefits of .NET APIs. Anything you can do in Android or in iOS, you can do with Xamarin using C#.WindowsWindows already supports C# for development.

Apps with some parts of the UI created using Xamarin.Forms and rest using native UI Toolkit can also be built using this approach.What Is Xamarin.Forms?Xamarin.Forms is a cross-platform natively backed UI toolkit abstraction that allows developers to easily create user interfaces that can be shared across Android, iOS, Windows, and Windows Phone.PerformanceXamarin apps are fully native so in xamarin you can enjoy fully native performance with shared code.Xamarin.iOS and Xamarin.Android (Separate UI)For Xamarin.iOS and Xamarin.Android, you have shared code base in C# .This business logic is shared across platforms and UI is separate for all platforms. This is separate UI approach. Xamarin.ios and Xamarin.Android give you 100% API coverage with benefits of .NET APIs. Anything you can do in Android or in iOS, you can do with Xamarin using C#.WindowsWindows already supports C# for development. So, it is also built in C# with native APIs.Xamarin.FormsXamarin.forms allow you more code sharing that you can also share application UI in all platforms.Included in Xamarin.FormsUI building blocks like pages, layouts, and controlsXAML-defined UIData bindingNavigationAnimation APIDependency ServiceMessaging CenterAdvantages of Xamarin.FormsNative appsShared Business LogicShared UIOne Xamarin development team require to develop apps for multiple platformsLess development time

What You Will Learn Share C# code across platforms and call native Objective-C or Java libraries from C# Submit your app to the Apple App Store and Google Play Use the out-of-the-box services to support third-party libraries Find out how to get feedback while your application is used by your users Create shared data access using a local SQLite database and a REST service Test and monitor your applications Gain memory management skills to avoid memory leaks and premature code cycles while decreasing the memory print of your applications Integrate network resources with cross-platform applications Design and implement eye-catching and reusable UI components without compromising on nativity in mobile applications 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 iOS, Android and Windows Phone, while leveraging the best native features on all three platforms. Xamarin's tools help ease this problem by giving developers a single toolset to target all three platforms. The main goal of this course is to equip you with 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. You will master the steps of getting the app ready and publishing it in the app store. The last module starts with general topics such as memory management, asynchronous programming, local storage, networking, and platform-specific features. You will learn about key tools to leverage the pattern and advanced implementation strategies. Finally, we 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. Style and approach This course will serve as comprehensive guide for developing cross-platform applications with Xamarin with a unique approach that will engage you like never before as you create real-world cross-platform apps on your own.
