		// This file is a snapshot of an AIDL file. Do not edit it manually. There are

		// 1). this is a frozen version file - do not edit this in any case.
		// 2). this is a 'current' file. If you make a backwards compatible change to
		// the interface (from the latest frozen version), the build system will
		// prompt you to update this file with `m <name>-update-api`.
		//
		// You must not make a backward incompatible change to any AIDL file built
		// with the aidl_interface module type with versions property set. The module
		// type is used to build AIDL files in a way that they can be used across
		// independently updatable components of the system. If a device is shipped
		// with such a backward incompatible change, it has a high risk of breaking
		// later when a module using the interface is updated, e.g., Mainline modules.
