Question

Accepted Answer

Android life cycle, fragments vs activities, API, services, and intents.

Android life cycle refers to the stages an Android app goes through from creation to destruction.
Activities are UI components that represent a single screen with a user interface, while fragments are reusable UI components that can be combined to create an activity.
API stands for Application Programming Interface, which is a set of protocols, routines, and tools for building software applications.
Services are background processes that can run even when the app is not in the foreground.
Intents are messages that allow components to request actions from other components, either within the same app or in a different app.
