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

+// 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.
