How to specify admob library in build.gradle?

Question

Can I specify the AdMob library in the build.gradle in Android Studio to avoid having the AdMob jar locally?

I've tried

dependencies {
    compile 'com.google.ads:6.2.1+'
}

but it doesn't work. Am I missing something?

Better if you use following:

compile 'com.google.android.gms:play-services-ads:7.5.0'

Because, it will reduce your apk file size.
