GradleFile:

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

android {
    compileSdkVersion 26
    buildToolsVersion '27.0.3'

    defaultConfig {
        applicationId "PackageName"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 20
        versionName "20.0"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    configurations {
        all*.exclude group: 'com.squareup.okhttp3', module: 'okhttp'
    }

    testOptions {
        unitTests.returnDefaultValues = true
    }

}

crashlytics {
    enableNdk true
    androidNdkOut 'src/main/obj'
    androidNdkLibsOut 'src/main/libs'
}

repositories {
    mavenCentral()
    maven { url 'https://maven.fabric.io/public' }
    google()
    jcenter()
    maven { url 'https://github.com/leonardocardoso/mvn-repo/raw/master/maven-deploy' }
}


dependencies {
    //Dependencies 
}

// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'

EDIT: I have Added the crashlytics key in manifest

<meta-data
            android:name="io.fabric.ApiKey"
            android:value="bddb9792335804f5fee7" />
