Adding a bootstrapper in Android

Just as for iOS, the bootstrapper for Android is a simple wrapper for the common bootstrapper defined in the .NET Standard library, but with the addition of an Init method that is called at startup:

1.  In the root of the Android project, create a new class called Bootstrapper.cs.
2. Add the following code to it:

public class Bootstrapper : DoToo.Bootstrapper
{
    public static void Init()
    {
        var instance = new Bootstrapper();
    }
}

We then need to call this Init method. A good place to do this is right before the LoadApplication call in OnCreate:

1. Open up MainActivity.cs.
2. Locate the OnCreate method and add the code in bold from the following code block:

protected override void OnCreate(Bundle savedInstanceState)
{
    TabLayoutResource = Resource.Layout.Tabbar;
    ToolbarResource = Resource.Layout.Toolbar;

    base.OnCreate(savedInstanceState);
    
    Xamarin.Essentials.Platform.Init(this, savedInstanceState);
    global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
    Bootstrapper.Init();
    LoadApplication(new App());
}
