android - android apk 中的 protobuf.meta 是什么？

Question

我最近更新了我的代码库以使用 v25.1.0 中的 v27.0.2 库，并开始在我的 apk 中看到一个“protobuf.meta”文件。有谁知道这是干嘛的？有没有办法从发布的 apk 中删除它，如果我这样做会有什么不好的后果吗？

Answer 1

protobuf.meta 即 Protocol Buffers

Protocol buffers are a flexible, efficient, automated mechanism for serializing structured data – think XML, but smaller, faster, and simpler. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages. You can even update your data structure without breaking deployed programs that are compiled against the "old" format.
