您可能使用了错误版本的 firebase-ui-database。根据github page它修复了对 com.google.firebase 版本的依赖关系。这意味着您必须确保 com.firebaseui:firebase-ui-database:0.6.2 支持 com.google.firebase:firebase-core:9.0.0。

您可以使用 gradle 依赖关系树进行检查，或者使用开发人员的预定义建议之一，例如

FirebaseUI 版本 Firebase/Play 服务版本
2.2.0 11.0.4
2.1.1 11.0.2
2.0.1 11.0.1
1.2.0 10.2.0
1.1.1 10.0.0 或 10.0.1
1.0.1 10.0.0 或 10.0.1
1.0.0 9.8.0
