Overview of this book

<p>Xamarin is the most powerful cross-platform mobile development framework. If you are interested in creating stunning user interfaces for the iOS and Android mobile platforms using the power of Xamarin and Xamarin.Forms, then this is your ticket.</p> <p>This book will provide you the practical skills required to develop real-world Xamarin applications. You will learn how to implement UI structures and layouts, create customized elements, and write C# scripts to customize layouts. You will create UI layouts from scratch so that you can tweak and customize a given UI layout to suit your needs by using Data Templates.</p> <p>Moving on, you will use third-party libraries – such as the Razor template engine that allows you to create your own HTML5 templates within the Xamarin environment – to build a book library Hybrid solution that uses the SQLite.Net library to store, update, retrieve, and delete information within a SQLite local database. You’ll also implement key data-binding techniques that will make your user interfaces dynamic, and create personalized animations and visual effects within your user interfaces using Custom Renderers and the PlatformEffects API to customize and change the appearance of control elements.</p> <p>At the end of this book, you will test your application UI for robust and consistent behavior and then explore techniques to deploy to different platforms.</p>

In this section, we will begin by creating our FacebookApiUser data model, which will be used to store our Facebook login information from when we create our backend service calls, and then the FacebookCredentials.cs and FBSignInRenderer.cs files will communicate and interact with our Facebook TrackMyWalks App ID to retrieve Facebook related information, as well as allowing the user to post walk information to their Facebook wall.

Let's now start to implement the code required for our FacebookApiUser class model by performing the following steps:

  1. Create an empty class within the Models folder by choosing Add | New File.... If you can't remember how to do this, you can refer to the section entitled Creating the...
