Xamarin Native equivalent of Xamarin.Forms App OnSleep and OnResume

Question

I'm working with a Xamarin Native application, and would like to perform some logic when the application is focused / out of focused in android - similar to Xamarin.Forms Application.OnSleep(), and Application.OnResume() (not to be confused with Activity.OnResume, and Activity.OnPause)

Just wondering what solution others have used to solve this scenario (besides migrating to Xamarin.Forms).

Answer 1

[Application]
public class MyApp : Application, ILifecycleObserver
{
    [Export, Lifecycle.Event.OnStop]
    public void OnAppBackgrounded()
    {
    }

    [Export, Lifecycle.Event.OnStart]
    public void OnAppForegrounded()
    {
    }

    public override void OnCreate()
    {
        // For handling when the app goes into the foreground or background
        ProcessLifecycleOwner.Get().Lifecycle.AddObserver(this);
    }

So far it appears to work as expected. ProcessLifecycleOwner is in the Xamarin.Android.Arch.Lifecycle.Extensions nuget package.
