As you’ve learned, the theory behind the Android UI architecture is that developers should decompose their application into distinct activities Each activity is implemented as an Activity, and each is reachable via intents, with a “main” activity being the one launched by the Android launcher. For example, a calendar application could have activities for viewing the calendar, viewing a single event, editing an event (including adding a new one), and so forth.
