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

+// 2). this is a 'current' file. If you make a backwards compatible change to

+// You must not make a backward incompatible change to any AIDL file built

+// 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
