Android Studio || GDK 'hello word' || import com.google.android.glass.app.Card || Cannot Resolve Symbol 'google'

What I am trying to do with my google glass is pretty simple: create/display a hello world card for google glass

issue is::

when i add this:

import com.google.android.glass.app.Card

I get This:

Cannot Resolve Symbol 'google'

I did this:

Minimum and Target SDK Versions: 15 (There is only one Glass version, so minimum and target SDK are the same.) Compile with: Glass Development Kit Sneak Peek

and i made a change to the gradel.build[compile sdk version...it was 15/changed to what is below]

android {
    compileSdkVersion "Google Inc.:Glass Development Kit Sneak Peek:15"
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 15
    }
}

I feel like I'm missing something simple/a set up issue/not sure what it is.

got any suggestions?
