Android Google TV 配对协议不起作用

Question

当我尝试使用此代码执行 android 程序时，我使用 google 协议缓冲区获取此错误列表。问题可能出在哪里？

我在 app.gradle 文件中使用 protobuf gradle 插件版本 0.8.8 和 com.google.protobuf:protoc 版本 3.0.0 和 com.google.protobuf:protoc-gen-javalite 依赖项

问题是我实现了旧版本的 ProtoBuf，而且我使用了 .jar lib 文件。

我删除 .jar 文件并升级 protobuf 版本，它可以工作。
