问题描述
我无法将 Firebase身份验证 n与 FirebaseUI 结合使用.当我运行我的应用程序时，出现以下问题:默认FirebaseApp在此过程中未初始化.请确保先调用FirebaseApp.initializeApp(上下文)."
I'm having trouble using Firebase authentication in conjunction with FirebaseUI. When I run my application the following problem appears: "Default FirebaseApp is not initialized in this process. Make sure to call FirebaseApp.initializeApp (Context) first."
在我的应用程序/build.gradle中，我具有依赖项:
In my app / build.gradle I have the dependencies:
implementation 'com.google.firebase: firebase-core: 16.0.1'
implementation 'com.google.firebase: firebase-auth: 16.0.1'
implementation 'com.google.firebase: firebase-database: 16.0.1'
implementation 'com.firebaseui: firebase-ui-auth: 4.1.0'
和最后的"apply plugin: 'com.google.gms.google-services".
在我的模块/build.gradle中，我具有依赖项:
in my module / build.gradle I have dependency:
classpath 'com.google.gms: google-services: 4.1.0'
classpath 'com.android.tools.build:gradle:3.3.0-alpha07'
我已经将googleservices.json导出到"app"文件夹.我没有选择余地，问题仍然存在.有什么建议吗?
I have already exported my googleservices.json to the "app" folder. I was left with no options and the problem continues. Any suggestions?

implementation 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
}
apply plugin: 'com.google.gms.google-services'
推荐答案
尝试这样做:
implementation 'com.google.firebase:firebase-core:16.0.3'
implementation 'com.google.firebase:firebase-auth:16.0.3'
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.firebaseui:firebase-ui-auth:4.1.0
并更改此内容:
classpath 'com.android.tools.build:gradle:3.3.0-alpha07'
到
classpath 'com.android.tools.build:gradle:3.1.4'
