Android : GoogleMap class not found

I am adding play services in gradle, but I It does not give me GoogleMap class.

I am getting compiler error in import:

import com.google.android.gms.maps.*;

This my gradle file:

dependencies {
    compile 'com.google.android.gms:play-services:7.0.0'
}

Any idea what am I missing?

Been trying to rebuild the project, reimport gradle and do clean.
