Android里面是没有这个AtomsProto.java文件的 应该是服务器编译环境问题

Answer 1

原因：执行frameworks/base/cmds/statsd/src/atoms.proto的解析生成AtomsProto.java文件后，android的编译系统会对这个java文件进行压缩，用的是android编译环境里面的soong_zip工具。soong_zip在多核处理下估计是有bug，会导致文本错位，AtomsProto.java由于代码很多因此很容易出现压缩错误问题，后面就编译失败了。
修复方法：build/soong/java/proto.go里面，soong_zip压缩指令里面添加参数，强制不使用多核：
