Signature Permission Allowlist:
Android 15 introduces an explicit allowlist for platform signature permissions that are requested by nonsystem apps or newly requested by updates to system apps.
What It Is:
- Platform Signed Apps: These are apps that have the same signing certificate as the Android system. They can be system apps (built into the device) or non-system apps (installed later).
- Signature Permissions: These are special permissions defined by the Android system that can only be granted to apps with the right signing certificate.
Key Points:
1. Manufacturers' Control: Since Android 15, device manufacturers can control which permissions platform signed non-system apps can use by adding them to a specific list (allowlist).
2. Allowlist Function: If a non-system app is not on the allowlist, it can't use certain permissions on standard (non-debuggable) builds. This means the app will act like it’s not platform signed and won't get those special permissions.
3. Debuggable Builds: In builds meant for testing (debuggable), the system doesn't enforce the allowlist. This makes it easier for developers to test their apps.
4. System Apps: The permissions of system apps aren’t affected by this change, but any new permissions that a system app wants after an update must still be added to the allowlist.
Adding and Customizing an Allowlist:
- Allowlists can be stored in one or more XML files in a specific directory on the device. Manufacturers can organize these files however they want.
Overall, The signature permission allowlist is a way for device manufacturers to control app permissions based on their signing certificates, ensuring only approved apps can access certain features while making testing easier during development.
