我正在尝试测试已部署后端并且可以访问管理员的 Google App Engine - Mobile Backend Starter 。

问题出在 Android 客户端中，它在尝试从客户端发送消息时抛出此错误：

我不明白Not Found这里是什么？我的意思是我确定我已经正确输入了 PROJEC_ID。

I/CloudBackend(675): com.google.api.client.googleapis.json.GoogleJsonResponseException: 404 Not Found

A404 not found表示它正在向错误/没有网站的地址发出 HTTP 请求。

所以我猜你在设置过程中在某处提供了错误的 URL？
