Android Google云端点错误：包MyApi不存在

我在运行MainActivity时收到以下

错误：包MyApi不存在

消息。StackOverFlow中也有类似的帖子，但解决方案不适合我

没有日志跟踪。发生的事情是，

myApi

这是googlecloudmodule后端类中API的名称，没有被识别，我真的不知道为什么

我的Api所在的类（模块后端） 试图从中访问API的类（模块应用程序） Build.gradle文件（模块后端） 顶级Build.gradle文件

---

根据，它应该是

endpointsServer项目（路径：：server），配置：“endpoints”）

可能与@DaltonCézane重复，这似乎是相同的错误，但该帖子上的解决方案对我面临的错误不起作用。根据，它应该是

endpointsServer项目（路径：：server），配置：“endpoints”）

@saiyr它现在对我起作用了！当我在尝试之前错过endpoints framework客户端插件时，它还是崩溃了。非常感谢你的帮助。将你的评论粘贴为答案，这样我就可以将它标记为正确的答案。
