Java.lang.NoClassDefFoundError: com.google.android.gms.common.GooglePlayServicesUtil

I am trying to create a basic Google Cloud Messaging application, however I am getting the following error:

    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 16
    }
    buildTypes {
        release {
            runProguard true
            proguardFile getDefaultProguardFile('proguard-android.txt')
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:+'
    compile 'com.google.android.gms:play-services:4.0.30'
}

I am using Android Studio. Can someone help me solve the problem?
