android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.ekaldroid.chat"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

试试这个

implementation 'com.google.android.gms:play-services-auth:11.4.2'
implementation 'com.google.android.gms:play-services-ads:11.4.2'
implementation 'com.google.firebase:firebase-appindexing:11.4.2'
implementation 'com.google.firebase:firebase-ads:11.4.2'
implementation 'com.google.firebase:firebase-storage:11.4.2'
implementation 'com.google.firebase:firebase-config:11.4.2'
implementation 'com.google.firebase:firebase-messaging:11.4.2'
implementation 'com.google.firebase:firebase-core:11.4.2'
implementation 'com.google.firebase:firebase-auth:11.4.2'
implementation 'com.google.firebase:firebase-database:11.4.2'
implementation 'com.firebaseui:firebase-ui-database:3.1.0'

或者这个

implementation 'com.google.android.gms:play-services-auth:11.8.0'
implementation 'com.google.android.gms:play-services-ads:11.8.0'
implementation 'com.google.firebase:firebase-appindexing:11.8.0'
implementation 'com.google.firebase:firebase-ads:11.8.0'
implementation 'com.google.firebase:firebase-storage:11.8.0'
implementation 'com.google.firebase:firebase-config:11.8.0'
implementation 'com.google.firebase:firebase-messaging:11.8.0'
implementation 'com.google.firebase:firebase-core:11.8.0'
implementation 'com.google.firebase:firebase-auth:11.8.0'
implementation 'com.google.firebase:firebase-database:11.8.0'
implementation 'com.firebaseui:firebase-ui-database:3.2.2'

FirebaseUI 的每个版本都依赖于这些库的固定版本，

3.2.2               11.8.0
3.1.3               11.8.0
