现有的Android App集成到Firebase

Question

按下以下按钮会在图像下方显示错误.

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. 
Client Package Name: packagename
Client SHA1: [59:17:0C:D9:63:14:42:A5:81:13:20:F8:58:0F:96:D8:6A:65]

我Connect to an existing Project list在错误消息中找不到提到的内容.

我通过单击"导入Google项目"按钮并选择现有的Google项目在firebase中创建了该项目.后来我尝试添加调试和生产签名SHA1,但这没有帮助.

有谁遇到过同样的问题？

编辑:今天现有的项目列表对话框开始出现,但即使我从现有的项目列表中选择,我仍然会收到错误.我开始认为这是一个预览错误.:(

我能够通过在 Firebase 控制台的项目设置中将调试证书指纹 (SHA-1) 添加到 Android 应用程序来连接我们现有的 Firebase 应用程序。

您可以使用 keytool 从调试证书中获取指纹：

keytool -exportcert -list -v \
-alias androiddebugkey -keystore ~/.android/debug.keystore
