适用于Android的Xamarin.Forms通知服务

Question

I'm relatively new to Android app development and Xamarin.Forms development in general, so I'm looking for an advice on what is the best way to implement the following: When active, my app downloads data using a simple REST appi service (I'm using a HttpClient for this). Now what I want is when the app is closed, to still check if some data is changed on the server, using the same method as it was used when the app is running, and if so, to fire up the notification to the user. I've been reading about the services, and that seems like a solution to my problems, but what I need to know is: what kind of service is most suitable for this task? Is it a Bound service, Intent service or Started service? Or is there a way to achieve this without the use of the service?
