And here's my build gradle

implementation 'com.firebaseui:firebase-ui-database:3.3.1'
implementation 'com.google.firebase:firebase-database:11.8.0'
implementation 'com.firebaseui:firebase-ui-auth:3.3.1'
implementation 'com.google.firebase:firebase-auth:11.8.0'
implementation 'com.google.firebase:firebase-storage:11.8.0'
implementation 'com.google.android.gms:play-services-auth:11.8.0'

Update your dependencies. firebase-ui-database is on 4.2.0, firebase-database is on 16.0.1, firebase-ui-auth is on 4.2.0, firebase-auth is on 16.0.3, firebase-storage is on 16.0.4, play-services-auth is on 16.0.0. — TheWanderer

I had similar issue and tried many things. I suggest two things which can solve your problem. 1. try adding this in your project build.gradle

buildscript {

    repositories {
        google()
        maven {url "https://maven.google.com"}
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
        classpath 'com.google.gms:google-services:4.0.1'



        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
    }

    allprojects {
        repositories {
        google()
        maven {url "https://maven.google.com"}
        jcenter()
    }
    }

    task clean(type: Delete) {
        delete rootProject.buildDir
    }

if this doesn't solve problem then: 2. then in your gradle I can see Firebase versions are different. try implement save versionsenter code here
