Why am I getting "unsupported version of Gradle" with the tutorials app in Android Studio?

When I try to import the tutorials app to Android Studio, I get this message:

The project is using an unsupported version of Gradle.

Please point to a supported Gradle version in the project's Gradle settings or in the project's Gradle wrapper (if applicable.)

I’m new to Android Studio, and meter too. What’s the problem with Gradle?

I’m using Android Studio 1.0.1.

Android Studio 1.0.1 supports gradle 2.2.1+ and Android Gradle Plugin 1.0.0+

How to change the gradle version.

In your project you should have a folder gradle/wrapper. Inside you will find the gradle-wrapper.properties file.

Change this line inside

distributionUrl=https\://services.gradle.org/distributions/gradle-2.2.1-all.zip

How to change gradle plugin version:

In your project you should have a build.gradle file in the root folder.

Inside:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()   // or mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'        
    }
}

Pay attention. Each module has a own build.gradle file. Inside you can override the default configuration.
