           this my build.gradle (project:SkypeClone)

Answer 1

Here is the code.

    // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.1'
        classpath 'com.google.gms:google-services:4.3.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven{ url 'https://maven.google.com' }
        maven{ url 'https://tokbox.bintray.com/maven' }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

This is the second file
