What entities are described in the AndroidManifest.xml file?

The AndroidManifest.xml file describes the key entities and configuration of an Android application, including:

• Application package (package) — a unique identifier for the application.
• Application components:
  • Activity — application screens.
  • Service — background services.
  • BroadcastReceiver — receivers for system and user messages.
  • ContentProvider — data providers.
• Permissions — rights requested or granted by the application.
• Intents and intent filters — to define what actions and data the component supports.
• Minimum and target SDK versions — requirements for the Android version.
• Hardware and software requirements — e.g., camera or sensors availability.
• Theme settings, icons, and other application resources.

Example of an Activity declaration in the manifest:

<activity android:name=".MainActivity">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
