Answer 1

jcenter() is now deprecated.

Use this in build.gradle of app: 'com.android.volley:volley:1.2.0'

And this in build.gradle:

Click to copy

repositories {
    google()
    mavenCentral()
}

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,

Click to copy

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

Click to copy

   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.

Answer 3

Add this snippet to your build.gradle file,

Click to copy

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

and replace with this -

Click to copy

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

Click to copy

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