I was trying to create a messaging feature for my application. However, I no longer have to create this feature and I don't know what code I need to delete so that these errors will no longer occur:

Gradle sync failed: Cannot resolve external dependency
com.google.gms:google-services:4.2.0 because no repositories are
defined. Required by: project : Consult IDE log for more details (Help
| Show Log) (504 ms)

Here's my gradle file:

apply plugin: 'com.android.application'

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







android {

    compileSdkVersion 28

    defaultConfig {

        applicationId "com.android.SPELFIT.profile"

        minSdkVersion 15

        targetSdkVersion 28

        versionCode 1

        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }

    buildTypes {

        release {

            minifyEnabled false

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

        }

    }

}



dependencies {

    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support:appcompat-v7:28.0.0'

    implementation 'com.android.support.constraint:constraint-layout:1.1.3'

    testImplementation 'junit:junit:4.12'

    androidTestImplementation 'com.android.support.test:runner:1.0.2'

    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'



}



dependencies {

    implementation ('com.h6ah4i.android.widget.advrecyclerview:advrecyclerview:0.11.0@aar'){

        transitive=true

    }

}





repositories {

    jcenter()

}

add google repo.

repositories {

        jcenter()

        google()

    }

Add google() as the first repo for all your

buildscript {

    repositories {

        google() // must be the first one!!!!

        jcenter()

    }

}

And

allprojects {

    repositories {

        google() // must be the first one!!!!

        jcenter()

    }

}

Cannot resolve external dependency
com.google.gms:google-services:4.2.0

Find project root build.gradle file

buildscript {



   repositories {             // add this tag, if you don't have with repo

      google()

      jcenter()

   }



   dependencies {

      classpath 'com.android.tools.build:gradle:3.2.1'

      classpath 'com.google.gms:google-services:4.2.0'

   }

}

Hopefully you've proper net connection and make sure you've not checked Offline work in Global Gradle settings.
