Question

I was reading this two docs about Service in the Android SDK

http://developer.android.com/reference/android/app/Service.html
http://developer.android.com/guide/components/services.html

I would like you to explain how the following architecture should be implemented.

I need a Service that every X minutes checks $something, updates a db and eventually notify on the status bar the updates.

Then I need an Activity from where I have to read from the same db to show a more complete set of information.

The service basically has to run accordingly to a delay time and even if the Activity is not used.

Is it possible to have this “architecture” in a single apk?

Use AlarmManager and an IntentService. If you need the every-X-minutes logic to occur even if the device is asleep, you will need to use something like my WakefulIntentService.

Absolutely.
