即使SHA1正确，Google登录也会在Android上失败，代码为DEVELOPER_ERROR

我已经为Android应用程序实施了Google登录Firebase . 我已经按照官方指南（https://firebase.google.com/docs/auth/android/google-signin），我已经使用调试和发布HA-1指纹更新了设置，并且我一直收到相同的错误 . 调试版本工作正常，但发布版本不起作用 .

我运行命令

keytool -exportcert -list -v -alias -keystore

对于我的 生产环境 密钥库，我在部署时使用它来签署我的.apk，我已将sha1添加到Applications的Firebase设置中，但仍然收到错误 .

这是进行身份验证的类

我确信我在控制台上拥有正确的密钥库签名证书SHA1 . 我已经检查了数百次 . 我也确定我使用我用来生成保存在Firebase控制台上的SHA1的密钥库来签署我的应用程序 .

我还下载了我的android项目最新版本的google-services.json文件 .

有没有人知道为什么我在尝试使用Google登录时，在我的活动结果的状态代码中继续收到DEVELOPER_ERROR .
