How to correctly implement the architecture of a program section on Android?

Question

Android

There is MainActivity, a service for scheduling notifications, and a database with all scheduled notifications. What is the correct way to add and remove records to/from the database: in the activity or directly in the service itself, when calling the add/remove notification method?

Answer 1

I would do it in the service, because the activation has a higher chance of being killed by the system than the service.
