SetPage(Xamarin.Forms.Page)' is obsolete error - Android

Question

I have created a universal application with Xamarin Forms

I get the warning

Xamarin.Forms.Platform.Android.FormsApplicationActivity.SetPage(Xamarin.Forms.Page)' is obsolete

Has anyone come across this?

The code is shown below

public class MainActivity : AndroidActivity
{
    protected override void OnCreate (Bundle bundle)
    {
        base.OnCreate (bundle);

        Xamarin.Forms.Forms.Init (this, bundle);    
        SetPage (App.GetMainPage ());
    }
}

Forms 1.3.1 supports a new Application class that has a MainPage property, which allows you to set the App start page in a single location (rather than once per platform).

public class App : Application // superclass new in 1.3
{
    public App ()
    {
        // The root page of your application
        MainPage = new ContentPage {...}; // property new in 1.3
    }

A Migration Guide is available which outlines all of the changes you will need to make in your app for the new API.
