我在Firebase中解决了问题,因为Google登录需要在项目设置中添加SHA1指纹:

要为您的Android应用设置Google登录,您需要在"项目设置"中为每个应用添加SHA1指纹.

要获得发布和调试证书,请遵循Google API身份验证指南

关于模块错误...您检查过先决条件吗？

• 运行 Android 2.3 (Gingerbread) 或更高版本以及Google Play 服务 10.0.0或更高版本的设备

• Android SDK 管理器中的 Google 存储库

• Android Studio 1.5 或更高版本

尝试更新gradle这些，让我们看看它是否有效：

• com.google.firebase:firebase-database:10.0.0
• com.google.firebase:firebase-auth:10.0.0
