Try to move maven { url "https://jitpack.io" } inside allprojects > repositories instead of buildscript > repositories and tell me if it works.

Please go to File->Settings->Gradle. Uncheck the Offline work if it is checked and sync the project again. It worked for me. Happy coding!

Solved.

I'm getting error Failed to resolve: com.github.GrednerG:Toasty:1.1.2 whenever I try to build.

Here is my gradle file:

buildscript {
    repositories {
        mavenLocal()
        jcenter()
        maven { url "https://jitpack.io" }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
        classpath 'com.google.gms:google-services:3.0.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        jcenter()
    }
}

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