Conventions for the protos in this directory: 1. As in the rest of Android, use 4 spaces to indent instead of 2. 1. For protos based on Java files, use the same package as the Java file. For example, `com.android.server.thing` instead of `com.android.server.thing.proto`. 1. If the proto describes the top level output of dumpsys, it should contain `Dump`. This makes it easy to understand that the proto is the dumpsys output of a certain service, not the data structure of that service, e.g. `WindowManagerServiceDumpProto` vs `WindowManagerServiceProto`. * Inner messages whose containing messages have the `Proto` suffix do not need to have a `Proto` suffix. E.g: ``` message FooProto { message Bar { ... } } ``` vs ``` message FooProto { message BarProto { ... } } ``` 1. If the proto represents the structure of an object, it should have `Proto` as its suffix. Please also include the full package path of the original object as a comment to the proto message. 1. Include units in the field names. For example, `screen_time_ms` vs `screen_time`, or `file_size_bytes` or `file_size_mebibytes` vs `file_size`. 1. Leave field numbers 50,000 - 100,000 reserved for OEMs.
