Referencing the google-play-services library

Question

I\'m working on a project using the Google Maps Android API v2, and I have a problem when I start referencing google-play-services_lib. A red exclamation mark appears on my proj

Answer 1

What solved it for me was updating some packages ('sdk platform-tools', and 'sdk build-tools' were updated from 16 to 17) in the SDK manager. After that, everything was ok.

I spent nearly half a day to resolve this... I realize this will probably not help anyone, but for the remote 0.1% chance that this DOES help someone I decided to write up my answer here.

Hope this helps someone :-)
