Why are permission tags needed in Android?

Tags for permissions in Android are used for categorizing and grouping permissions, allowing for more granular management.

Main advantages of using tags:

• Identification: They allow for unambiguous determination of the type of permission (e.g., access to camera, contacts, geolocation).
• Control: They simplify permission management for users and the system, enabling related permissions to be grouped together when requested or displayed in settings.
• Security: Some tags (e.g., protectionLevel) indicate the level of permission protection, affecting how the system issues and verifies it.

Example of usage in the manifest:

<permission android:name="com.example.app.MY_CUSTOM_PERMISSION"
            android:label="@string/permission_label"
            android:description="@string/permission_description"
            android:protectionLevel="normal" /> // The protectionLevel tag indicates the level of protection
