firebaseUI dependency not matching with the firebase version 15.0.0

Question

firebaseUI dependency not matching with the firebase version 15.0.0 Actually what is happening is that, when I include the firebaseUI dependency , android studio shows some kind of error related to values.xml file. I have linked the picture of error below and when I remove that line everything works fine , then there is no error.

   The code for the entire gradle file is given below:

       apply plugin: 'com.android.application'
       repositories {
            mavenLocal()
            flatDir {
                dirs 'libs'
            }
            maven { url "https://maven.google.com" }

        }
            android {
            compileSdkVersion 24
            buildToolsVersion '26.0.2'
          defaultConfig {
                applicationId "com.google.firebase.udacity.friendlychat"
                minSdkVersion 16
                targetSdkVersion 24
                versionCode 1
                versionName "1.0"
                resConfigs "en"
            }
            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.google.firebase:firebase-database:15.0.0'
            compile 'com.google.firebase:firebase-auth:15.0.0'
            compile 'com.google.firebase:firebase-core:15.0.0'
            compile 'com.firebaseui:firebase-ui-database:3.3.0'
            compile 'com.android.support:design:24.2.0'
            compile 'com.android.support:appcompat-v7:24.2.0'
            compile 'com.github.bumptech.glide:glide:3.6.1'
        }apply plugin: 'com.google.gms.google-services'

Try updating your setup, also firebase UI is still depedning in version 12.0.1 not 15.0.0. See the docs to see which versions match with which firebase ui versions:

apply plugin: 'com.android.application'
   repositories {
        mavenLocal()
        flatDir {
            dirs 'libs'
        }
        maven { url "https://maven.google.com" }

    }
        android {
        compileSdkVersion 27
        buildToolsVersion '27.0.3'
      defaultConfig {
            applicationId "com.google.firebase.udacity.friendlychat"
            minSdkVersion 16
            targetSdkVersion 27
            versionCode 1
            versionName "1.0"
            resConfigs "en"
        }
        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.google.firebase:firebase-database:12.0.1'
        compile 'com.google.firebase:firebase-auth:12.0.1'
        compile 'com.google.firebase:firebase-core:12.0.1'
        compile 'com.firebaseui:firebase-ui-database:3.3.0'
        compile 'com.android.support:design:27.1.1'
        compile 'com.android.support:appcompat-v7:27.1.1'
        compile 'com.github.bumptech.glide:glide:3.6.1'
    }
