Android Studio 助手 : No clients were able to be added to your Firebase project

Question

在 Android Studio 中使用新的 (Firebase) 助手添加新服务时出现此错误:

Firebase

No clients were able to be added to your Firebase project for the following reasons: An app with this package name and SHA1 is already connected to a Google project. If you have used a Google API previously, please select that project in the Connect to an existing Project list.

关于 Firebase console page我选择了 IMPORT GOOGLE PROJECTS 选项，然后继续集成 Firebase 服务。但是，当我尝试使用 Android Studio Firebase 助手添加更多服务时，出现了上述错误。

而且我在任何地方都找不到这个“in the Connect to an existing Project list”？

Answer 1

你可以去Credentials page of Google Cloud console并管理您所有项目的凭据。

在我的例子中，我需要删除导致冲突的一个凭证(警告:为谨慎起见，请在删除之前下载它。或者只是修改它)。

^{如果您最近删除了您的 firebase 项目(像我一样)，请参阅:https://stackoverflow.com/a/45270281/5318303 .}
