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