permission

If not null, the name of an Android permission that an entity needs in order to launch and/or connect to the service host. This controls the value of the android:permission attribute of the service manifest entry for this service host. This configuration is unavailable (null) if an external IVI service host is referenced.

See Android permissions for system developers and Define a custom app permission.

Clients of the service host must request the permission in their AndroidManifest.xml file with the uses-permission element.
