java - Firebase/Android FirebaseUI Error

Question

I am trying to build an application in Android and I tried using the FirebaseUI, but I am getting this error:

error: cannot access zzeuq class file for com.google.android.gms.internal.zzeuq not found

Here is my gradle file.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.example.vanillatalk.vanillatalk"
        minSdkVersion 21
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1'
    compile 'com.android.support:design:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    implementation 'com.google.firebase:firebase-auth:11.6.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.firebase:firebase-database:11.6.0'
    implementation 'com.google.firebase:firebase-storage:11.6.0'
    implementation 'de.hdodenhof:circleimageview:2.2.0'
    compile 'com.theartofdev.edmodo:android-image-cropper:2.7.+'
    implementation 'com.squareup.picasso:picasso:2.71828'
    implementation 'com.firebaseui:firebase-ui-database:4.0.0'
}

apply plugin: 'com.google.gms.google-services'

I think that the error is related to missmatched versions of firebase, since it 11.6.0 and firebase-ui-database:4.0.0, but I cannot seem to find the correct versions for the firebase-ui-database that would match the 11.6.0?

Could anyone help?

If you want to use version 4.0 of firebase ui you need to update firebase dependencies:

implementation 'com.google.firebase:firebase-database:16.0.1'

For version 11.6.0 of firebase you should use version 3.x.x of Firebase UI, see this.
