App/Service to perform task every minute

[cpper]

Hi there

I want to build a small app for my Android 6.0 Galaxy S5 which downloads a webpage every minute, checks its source code, and if a particular string is found at a particular line number, fires a notification. The program should run in the background, and should not exit unless it's requested to. It would be great if it could survive the "End all apps" command from "Active applications" tab.

From what I've read, I would need to build a Service in order to achieve such thing. A straight forward method to do this would be to extend the Service class and to add the code for downloading the page, and do something like (the android version of) sleep(1m) in a loop. But I'm pretty sure there are better ways to achieve this.

Could you tell me please which classes I need to use(extend) to accomplish what I wish ?

There's a good tutorial here

So using the Service class is my best option ? I was just reading that the AlarmManager class could also come in handy.

If I were to do this, I'd write a Service.
