Android开发中Battery Historian遇到的问题

浏览本文，你可以获取以下信息
1. 解决执行 go run setup.go时，无法编译通过的问题；
2. 上传bgr.zip/bgr.txt后，Android Q无法解析的问题；
3. 搭建离线版Battery Historian

1. JS 编译问题

如下在执行go run setup.go时，会出现如下图片所示的报错，这个问题在最新的（2020.08.20）代码还是并未解决，不知道是什么时候引入的问题，可参考Github BatteryHistorian 183问题的描述，主要解决办法就是回退版本。如果你是从Github上单独拉的closure-library，需要先在你拉下来的路径下回退版本，再拷贝到third_party，无法直接在third_party/closure-library下回退，会提示“ambiguous argument ‘v20170409’: unknown revision or path not in the working tree.”；如果执行完go get -d -u github.com/google/battery-historian/...后，在third_party路径下有closure-library文件夹，那你可以直接在这回退版本

// 直接有closure-library文件夹
go run setup.go (this fails)
cd third_party/closure-library/
git reset --hard v20170409
cd -
go run setup.go (this passes)

//单独拉closure-library
cd closure-library
git reset --hard v20170409
拷贝closure-library到$GOPATH/src/github.com/google/battery-historian/third_party下
go run setup.go 

回退后，执行成功的界面

2. Android Q无法解析bugreport问题

如下图片，当你解决环境问题时，有Submit按钮，能上传log时，却发现打开的是这样的界面，提示" Could not parse aggregated battery stats."。这个问题原因应当是Android系统更新后，在代码中的有些参数变了导致解析失败，类似于0.0和0的问题，相关问题见GIthub BatteryHistorian 188的描述，解决方法见GitHub lilydjwg的提交。解决办法是修改本地工具代码，修改如下所示：

3. 搭建本地离线版Battery Historian

根据base.html的配置，当上传bugreport后，需要访问ajax.googleapis.com、cdnjs.cloudflare.com、https://www.google.com等资源，这些资源中，有部分资源由于墙的原因无法访问，创建离线版就是在本地提供这些资源，感谢GitHub用户gusha915提供的所需资源，具体操作如下：

1. 执行完go get -d -u github.com/google/battery-historian/…后，将下载好的base.html 替换原码下的 battery-historian\templates\base.html；
2. 下载好cdn目录 放入到battery-historian\third_party 目录；
3. 进行 cd $GOPATH/src/github.com/google/battery-historian；
4. 运行 go run setup.go 进行编译；
5. 运行 go run cmd/battery-historian/battery-historian.go
