    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
    }
}

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"
    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

Hey @MRFrhn thank you for your response, classpath 'com.android.tools.build:gradle:3.1.2' classpath 'com.google.gms:google-services:3.3.0' – Pretension

i have changed com.android.tools.build:gradle:3.1.2 to 2.3.3 in main build.gradlew file now i'm not getting that error, but how do i updrade the build.gradlew to new version without getting any errors – Pretension

keep the gradle version, change google-services to classpath 'com.google.gms:google-services:3.2.1' and try again. there seems to be an issue with 3.3.0 version – Questionless

Thank you! that worked fine. and can I use play-services:15.0.1 currently I am using 11.8.0. – Pretension

There seems to be an issue with google-services 3.3.0

Change it to classpath 'com.google.gms:google-services:3.2.1' and it should work fine.
