+// 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
+// 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.
