When I start up a new wearable project, or https://github.com/kentarosu/androidwear-myfirstwatchface from github, I get an error about missing the play library, is there something I need to do to install that onto the android studio (OS 10.9.5/Mavericks)?

Error:Failed to find: com.google.android.gms:play-services-wearable:+ Open File
Open in Project Structure dialog

Maybe this is a solution.
