Android app gradle build compilation issue with firebase-ui-auth

[Dan Belostotsky]

Hi,
 I'm following Udacity Firebase course and have a small issue while setting up authentication process.
 When i add:

compile 'com.firebaseui:firebase-ui-auth:3.2.2'

 to my app.grade build i get the following:


The whole file looks like:

apply plugin: 'com.android.application'

repositories {
    mavenLocal()
    flatDir {
        dirs 'libs'
    }
}

android {
    compileSdkVersion 27

    defaultConfig {
        applicationId "com.google.firebase.udacity.friendlychat"
        minSdkVersion 17
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE-FIREBASE.txt'
        exclude 'META-INF/NOTICE'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'

    compile 'com.android.support:design:27.1.0'
    compile 'com.android.support:appcompat-v7:27.1.0'

    // Displaying images
    compile 'com.github.bumptech.glide:glide:3.6.1'

    //Firebase
    compile 'com.google.firebase:firebase-core:11.8.0'
    compile 'com.google.firebase:firebase-database:11.8.0'
    compile 'com.google.firebase:firebase-auth:11.8.0'
    compile 'com.firebaseui:firebase-ui-auth:3.2.2'

}

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

Please assist.
Thank you.

Dan,

firebase-ui-auth itself has a dependency on com.android.support:cardview-v7, probably in version 27.0.2, which is older than the other support libraries you are including yourself. Try going through the "Updating dependencies" section here: https://github.com/firebase/FirebaseUI-Android#upgrading-dependencies

Thanks Andreas for answering!

Yes Dan the solution is in that link, specifically you'd want to add:
compile "com.android.support:design:27.1.0"          // You already have this

compile "com.android.support:customtabs:27.1.0"  // Add this

compile "com.android.support:cardview-v7:27.1.0" // Add this
