How to resolve "Duplicate class com.google.android.gms.common.api.zzb found in modules jetified-play-services-base-11.0.1-runtime.jar"

Issue

I am new in Android Studio Development. I am getting this error in my project.

Duplicate class com.google.android.gms.common.api.zzb found in modules jetified-play-services-base-11.0.1-runtime.jar

Here is my App Gradle dependencies code (build.gradle (Module: app))

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation 'com.google.android.gms:play-services-ads:18.3.0'
    implementation 'com.google.android.gms:play-services:11.0.1'
}

Here is the full error:

I am using FusedLocation Service as well as Google Ads (Admob) in my project.

import com.google.android.gms.common.api.GoogleApi;
import com.google.android.gms.location.FusedLocationProviderClient;
import android.location.Location;
import com.google.android.gms.ads.AdView;
import com.google.android.gms.ads.InterstitialAd;
import com.google.android.gms.ads.MobileAds;

public class MainActivity extends AppCompatActivity
{
    private AdView adView;
    private InterstitialAd interstitialAd;
    FusedLocationProviderClient client;
    ...

Solution

Remove this line:

implementation 'com.google.android.gms:play-services:11.0.1'

play-services-ads:18.3.0 will pull in a rather current version, which doesn't need to be jetified.
