文件 google-services.json 丢失。如果没有它，Google 服务插件就无法运行。（适用于 firebase ml 套件）

Question

我见过一些与此错误相关的类似问题。但我没能解决这个问题。我正在使用 firebase ml 套件来识别图像中的文本。我已将 google-services.json 文件添加到应用程序目录中，但仍然遇到相同的错误。如果有人可以解决这个问题请告诉我。

我收到以下错误：

File google-services.json is missing. The Google Services Plugin cannot function without it.
