Morning (from Denmark) guys. Quick question regarding "best practices". Would you add your business logic to an activity rather than a fragment? I'm talking specifically about making an HTTP request to fetch data, which are displayed in only 1 fragment. (List of students). Other two fragments don't use these data, but will perform different HTTP requests in the future. Therefore, in my opinion it would make sense to separate this logic between fragments instead of keeping everything in the MainActivity. I'll be happy to hear your opinions. Cheers.
