Android 应用问题：服务？

Question

I am currently programming an app that is supposed to get the users' calls and SMSs log and send them to a remote mysql DB.

I have a preferences screen and a checkbox for calls and another for sms logging and I want that when the user clicks in the checkboxes and then saves the preferences clicking a button, the logging starts to work (depending on whether the checkboxes were clicked or not).

My question is, should I implement each of the logging feature in services? Remote or locals? I'd like the logging working ALWAYS until the users unticks the checboxes and saves preferences. Should I send the data to the DB every x hours, or just storing everything in a SQLite DB in Android and then sending everything by the end of the day?

This is my first android app and as you can see I have no idea:)

Thanks everybody for your help! Cheers

I am finally using a remote service, as I want the service to be running even though the application might not be running, and will just send the data every 24h, so much better. Thanks for your help!
