无法连接到firebase

Question

我正在尝试使用Android studio提供的工具将我的Android应用程序连接到firebase，但我面临着很多麻烦。

我已经尝试更新依赖到最新的最新的谷歌服务，但错误仍然存在，显示的错误是无法解析Android应用模块的Gradle配置。解决分级生成问题和/或重新同步。

buildscript {
    repositories {
        mavenCentral()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        classpath 'com.google.gms:google-services:4.2.0'


    }
}

allprojects {
    repositories {
        mavenCentral()
        google() // here
    }
}

ext {
    compileSdkVersion = 22


    minSdkVersion = 9
    targetSdkVersion = 23
}

这是我的grade/app文件中所有的firebase/firestore实现。不知道这些是否有帮助。

    implementation 'com.google.firebase:firebase-firestore:17.1.2'

    implementation 'com.google.firebase:firebase-core:16.0.7'

    // FirebaseUI for Firebase Realtime Database
    implementation 'com.firebaseui:firebase-ui-database:4.3.1'

    // FirebaseUI for Cloud Firestore
    implementation 'com.firebaseui:firebase-ui-firestore:4.3.1'

    // FirebaseUI for Firebase Auth
    implementation 'com.firebaseui:firebase-ui-auth:4.3.1'

    // FirebaseUI for Firebase Auth (GitHub provider)
    implementation 'com.firebaseui:firebase-ui-auth-github:4.3.1'
