刚刚发现刚才那个创造了在开发者控制台项目应用客户端ID删除这个错误，并允许配置文件被创建...

Just found out a moment ago that creating a client ID for the app in developer console project removes this error and allows the config file to be created...

Developer console projects
APIs & auth
Credentials
Create new client ID:
  Installed application
  Android
  Enter package name
  Enter SHA1 for RELEASE OR DEBUG (which ever one you want it to work with)
  Make deep linking choice
  Create

然后又回到了页面和它的作品。可能是其他的东西在你需要做的，但IDK的，因为我已经有其他的东西设置控制台。

Then went back to the page and it works. Could be other stuff in the console that you need to do but idk as I already have other stuff set up.
