Overview of this book

Do you want to create powerful, efficient, and independent apps from scratch that will leverage the Xamarin framework and code with C#? Well, look no further; you’ve come to the right place! This is a learn-as-you-build practical guide to building eight full-fledged applications using Xamarin.Forms, Xamarin Android, and Xamarin iOS. Each chapter includes a project, takes you through the process of building applications (such as a gallery Application, a text-to-speech service app, a GPS locator app, and a stock market app), and will show you how to deploy the application’s source code to a Google Cloud Source Repository. Other practical projects include a chat and a media-editing app, as well as other examples fit to adorn any developer’s utility belt. In the course of building applications, this book will teach you how to design and prototype professional-grade applications implementing performance and security considerations.

Setting up MVVMCross with Android


As we already completed the PCL setup for MVVMCross, we only need to create the setup object, which will inherit the MvxAndroidSetup class.

Create a new file called AndroidSetup.cs and implement the following:

public class AndroidSetup : MvxAndroidSetup 
    { 
        public AndroidSetup(Context context) :base(context) 
        { 
        } 
 
        protected override IMvxApplication CreateApp() 
        { 
            return new App(); 
        } 
 
        protected override IMvxTrace CreateDebugTrace() 
        { 
            return new DebugTrace(); 
        } 
    } 

This is very much the same as the iOS setup, but in the constructor we must pass in the Android context.

Now for the final setup on Android. We don't normally have an application to override. Instead, MVVMCross by default provides a splash screen. Delete the MainActivity class that is automatically created, and replace it with a new activity called SplashScreenActivity:

[Activity(Label ...
