gms:play-services-ads:17.1.1 gives error All com.google.android.gms libraries must use the exact same version specification

Question

All com.google.android.gms libraries must use the exact same version specification (mixing versions can lead to runtime crashes).

Found versions 17.1.2, 16.0.5, 16.0.4, 16.0.1, 16.0.0. Examples include com.google.android.gms:play-services-ads-base:17.1.2 and com.google.android.gms:play-services-measurement-base:16.0.5

this the gradle I am using

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"
    defaultConfig {
        applicationId "com.hoper.friebasecrashalytics"
        minSdkVersion 14
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.0.2'
    compile "com.android.support:exifinterface:26.0.2"
    compile 'com.android.support:animated-vector-drawable:26.0.2'
    //compile 'com.google.firebase:firebase-core:16.0.5'
    compile  'com.google.android.gms:play-services-ads:17.1.1'
    //compile 'com.crashlytics.sdk.android:crashlytics:2.9.6'
    testCompile 'junit:junit:4.12'
}

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '26.0.2'
            }
        }
    }

}

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

even when we dont use firebase the error occurs

how can we solve this issue

Check which libraries are shown in the warning and implement them with the same version number. For example:

Warning shows:

com.android.support:customtabs:xx.x.x

You need to implement:

implementation 'com.android.support:customtabs:28.0.0'
