I was trying to get an environment setup today and after getting the SDK, ADT, Eclipse etc set up I imported the project to the new work space. After install developer tools version 22.0 the google play services lib in the project "can't be resolved". None of the map classes can be resolved - Marker, Camera Position, LatLng, Google Map etc.
In a different environment I was running version 21.1 of the Developer Tools. The project would run fine there until I updated the Developer Tools.
I was curious if anyone else has experienced this and if there is a workaround?
