The Android Manifest file is an essential configuration file in Android applications, providing metadata and permissions information to the system. It has four main components:
1. Manifest element: The root element containing package name and version details.
2. Application element: Defines application-level properties like icon, theme, and activities.
3. Activity elements: Declare individual screens or UI components within the app, specifying intent filters for navigation.
4. Permissions elements: Request access to device features and resources, such as camera, location, or internet.
These components work together to ensure proper functioning, security, and user experience of the app.
