An Activity represents a single screen in an Android application. It's a fundamental component that manages the user interface and interactions. It must be declared in the AndroidManifest.xml to be used.

What is the main difference between Activity and Fragment?

A Fragment is a modular and reusable sub-component that must be hosted within an Activity. An Activity is a standalone component representing a complete screen. An Activity can contain multiple Fragments, but a Fragment cannot exist without an Activity.

The AndroidManifest.xml file is essential for every Android application. It declares all app components (Activities, Services, Receivers, Providers), defines permissions, intent-filters, specifies metadata and the minimum supported Android version.
