我需要你的帮助......我不知道了!

我不明白为什么每次都失败。

• 我生成了 ID 客户端 OAuth 2.0。
• 我已生成 google-services.json 并将其移动到 ./app 文件夹中。
• 通过 Google Cloud Console，激活所有 Google API。

检查一下，如果有什么东西伤害了你......继续!

亲切的问候

最佳答案

对我来说，当应用程序使用不正确的证书签名时，证书 SHA-1 必须在 Google 控制台中注册。

对于调试构建变体，您可能还想将调试证书添加到 Google 控制台，或者为调试变体配置 build.gradle 以使用您在控制台中注册的相同证书。
