Overview of this book

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. Finally, you will learn how to write unit tests using the NUnit and UITest frameworks.

Working with the Razor Templating Engine

In the previous chapter, we learned how to work with the various Animation classes that come as part of the Xamarin.Forms platform, so that you can apply really cool animations and transition effects to your user interfaces and control elements. We learned how to work with and use simple animations within your XAML, as well as how to create the necessary C# code within your ContentPages to interact with your XAML control elements in order to apply various animation techniques to the controls that Rotate, Scale, Translate, and Fade.

We also learned about easing functions, and how you can implement these within your ContentPages using C# code by making use of the Easing class, which allows you to specify a transfer function that is able to control the speed of running animations by creating custom easing functions that are able to interact...
