well in my app I want the user to get notifications depending on the time is it. So, it must check all the time current date and time, and giving notification for the upcoming event.
I have found tutorials like these: tutorial 1
but all of these are triggered after pressing a button and setting something like an alarm.
But I want my app to be able to do that "checks" all the time. So do I have to use a service or is there any other way? I have never used services before that's why I am not sure if this is what I need or not.
EDIT: I cam wondering if using alarm. My problem in that case is that I do not any interference from the user. I mean he must not press a button to set the alarm but the app has to worki like this: first alarm at: sunday 9 october 11:00 next at: same day 18:00 next: 10 sept 07:00 and so on..
