Lcom / google / firebase / FirebaseApp类中没有虚拟方法

Question

在我的Android应用中，编译应用时出错。我正在最新的android studio中工作，并且使用Firebase UI Auth和Firebase数据库，所有版本在App级成绩文件中都相同，那么为什么我会收到此错误

错误：

升级以下内容：implementation 'com.google.firebase:firebase-database:11.8.0'implementation 'com.google.firebase:firebase-auth:11.8.0'implementation 'com.firebaseui:firebase-ui-auth:4.0.0'对此：implementation 'com.google.firebase:firebase-auth:16.0.2'implementation 'com.google.firebase:firebase-database:16.0.1'implementation 'com.firebaseui:firebase-ui-auth:4.1.0'还添加：implementation 'com.google.firebase:firebase-core:16.0.1'在顶级gradle文件中，升级google-service插件：classpath 'com.google.gms:google-services:4.0.1'https://firebase.google.com/support/release-notes/androidfirebaseui需要与firebase版本兼容，请查看以下链接以获取更多信息：https://github.com/firebase/FirebaseUI-Android/blob/master/README.md#dependencies
