error: In project 'app' a resolved Google Play services library dependency depends on another at an exact version

Question

I have been getting the following errors when I try to compile my project

ERROR: In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[15.0. 1]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

build.gradle(app)

apply plugin: 'com.android.application'
android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.example.spars.myapplication"
        minSdkVersion 16

    }

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
repositories {

}

        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '27.1.1'
            }
        }
    }

}

build.gradle(project)

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.android.tools.build:gradle:3.3.1'
        classpath 'com.google.gms:google-services:4.2.0'
    }
}

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

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

And I'm getting the following error

ERROR: In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[15.0. 1]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

For extended debugging info execute Gradle from the command line with ./gradlew --info :app:assembleDebug to see the dep endency paths to the artifact. This error message came from the google-services Gradle plugin, report issues at https:// github.com/google/play-services-plugins and disable by adding "googleServices { disableVersionCheck = false }" to your b uild.gradle file.

Please help

Answer 1

The issue probably arises due to your Firebase UI version not being compatible with the versions of the other dependencies of Firebase you are using (the other ones require a higher Google Play Services version).

If you look here you will see which versions your Firebase UI will require.

Maybe you should consider updating your Firebase UI version, because the current one is 4.3.1
