Android AppFunctions Beta Does Not Mean Open Agent Access

The AppFunctions guide describes a way for developers to declare app functions that the Android OS indexes using generated XML metadata. The Jetpack library generates the XML schema listing declared functions. Callers need the EXECUTE_APP_FUNCTIONS permission to discover and execute them, and the API is available on devices running Android 16 or higher. The documented flow is function-level. Callers can retrieve the metadata, check whether a function is enabled in a target app, and then select and execute it. These details describe how an app exposes functions for discovery and invocation.
