It's second day I've been fighting with Eclipse trying to import Google Maps API v2.
I have tried hundreeds of variant, but the library or is not imported and no accessible from my project or Unable to execute dex: Multiple dex files define Landroid/UnusedStub;
Android configurations[1]

Thank you
This means that somewhere the google play services JAR file is referenced more than once in your project.
Most likely once due to a library project dependency, and possible a second time as an Android dependency (by having the JAR file in your libs folder, or by referencing it some other way using a build configuration).
Remove all other references to Google Play Services and only keep the library project dependency. ADT will do the rest.
