Answer 1

Add this snippet to your build.gradle file,

allprojects {
    repositories {
        google()
        jcenter()
    }
}

and replace with this -

buildscript {
    repositories {
        google() // Just google() will be fine
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'com.google.gms:google-services:3.1.0'
    }
}

If, you are using gradle version lower than 4.1 - replace
google()
with

maven {
    url 'https://maven.google.com'
}

Answer 2

One of the solutions below must solve your problem:

1- If you've added the following line in your "module/app" build.gradle,

compile 'com.android.volley:volley:1.1.0'

you need to have the following code in your "project" build.gradle in order to enable your programming environment to find and download volley package

   allprojects {

    repositories {
         jcenter()
    }
}

2- You are living in a country which is under U.S. and International sanctions and that's why your programming environment cannot connect automatically to jcenter(bintray.com) to download the library, even though you've added jcenter to your repo list. If so, you have to use a proxy while syncing gradle.
