This book will provide you with the knowledge and practical skills that are required to develop real-world Xamarin and Xamarin.Forms applications. You’ll learn how to create native Android app that will interact with the device camera and photo gallery, and then create a native iOS sliding tiles game. You will learn how to implement complex UI layouts and create customizable control elements based on the platform, using XAML and C# 7 code to interact with control elements within your XAML ContentPages. You’ll learn how to add location-based features by to your apps by creating a LocationService class and using the Xam.Plugin.Geolocator cross-platform library, that will be used to obtain the current device location. Next, you’ll learn how to work with and implement animations and visual effects within your UI using the PlatformEffects API, using C# code. At the end of this book, you’ll learn how to integrate Microsoft Azure App Services and use the Twitter APIs within your app. You will work with the Razor Templating Engine to build a book library HTML5 solution that will use a SQLite.net library to store, update, retrieve, and delete information within a local SQLite database.

Creating and using Simple Animations in Xamarin.Forms

In this section, we will take a look at how to work with Simple Animations in your Xamarin.Forms XAML and ContentPages using C#.

Simple Animations make use of the ViewExtensions class, which provides you with extension methods that can be used to construct simple animations. The ViewExtensions class provides you with a LayoutTo extension method, which is only intended for use with layouts to animate transitions between layout states that contain size and property changes, and should only be used by classes that use the Layout subclass.
