What is the role of the AndroidManifest.xml file in an Android application structure?

The AndroidManifest.xml file is the main configuration file of an Android application, which describes the structure and components of the application for the Android system.

The role of the file:

• Declaration of application components: activities, services, receivers, content providers.
• Definition of permissions: which system resources or data the application can use.
• Configuration of entry points: for example, specifying the main activity with an intent-filter to launch the application.
• Definition of hardware and software requirements: minimum SDK version, supported screens, device features.
• Specifying default themes and styles.
• Configuration of application parameters: such as operation modes, configurations, metadata.

Without AndroidManifest.xml, the Android system will not be able to correctly launch and manage the application.
