错误:Firebase Auth Android 中的新遗物检测错误

Question

我收到与Firebase Chat Demo相关的错误，

当我从中创建FirebaseAuth实例时出现此错误

FirebaseAuth.getInstance((;

我已经上传了 Github.com 的项目，所以你可以看看它。该项目在一个月之前运行良好，因为我还没有打开它，但现在它给出了这种类型的错误

项目链接： https://github.com/raghavsatyadev/FirebaseChatDemo

请不要给出建议：项目清理，重新安装应用程序，卸载应用程序，因为我已经重新克隆了整个项目并卸载了以前的应用程序。
