Android Background Service vs AlarmManager

Question

Can someone give a little bit briefing or perhaps more elaborate details on differences Android background service with Alarm Manager?

How they differ? And in which situation I should use each?

I am developing an application that need to download data from Web Service at periodic time. The application has few modules and each modules has different interval time period to download / sync the data to Web Service.

Let say + Module A need to sync in every 15 mins + Module B need to sync in every 1 hour + Module C need to sync in every day + Module D need to sync weekly + Module E need to sync monthly

Which approach is better? And why?

Regards

AlarmManager schedule the intents. Your service can crash and be removed if memory is not available. But with AlarmManager you can invoke your specific service at a scheduled time. In your context, AlarmManager is a better option than a running service.

Hope it will help you.
