Adding an Android Application class

Create a new activity class called SpashScreen to the root folder of the MvvmCrossDemo.Droid project. Then update it like this:

using Android.App;
using Android.Content.PM;
using MvvmCross.Core;
using MvvmCross.Platforms.Android.Core;
using MvvmCross.Platforms.Android.Views;

namespace MvvmCrossDemo.Droid
{
    [Activity(
        Label = "MvvmCrossDemo.Droid"
        , MainLauncher = true
        , NoHistory = true
        , ScreenOrientation = ScreenOrientation.Portrait)]
    public class SplashScreen : MvxSplashScreenActivity<MvxAndroidSetup<Core.App>, Core.App>
    {
        public SplashScreen()
            : base(Resource.Layout.SplashScreen)
        {
            
        }
    }
} 

The SplashScreen class inherits from MvxSplashScreenActivity, Core.App>. You can find the source code here: https://github.com/MvvmCross/MvvmCross/blob/develop/ContentFiles/Android/SplashScreen.cs.pp.

The value of the NoHistory property in the attribute is true so if users press the back button the splash screen should not be returned.

This is the basic setting for the Android application to make sure it follows the pattern of MvvmCross. For simplicity, we use the MvxAndroidSetup class, which is the default Setup class and takes responsibility for bootstrapping MvvmCross and registering platform service. We can use a customized Setup class and get more details in the next sections. Note that if you changed the name of App class in the Core project, you need to update it here.
