Android - Google Maps API v2 - NoClassDefFoundError

view story

http://stackoverflow.com – I try to run Google Maps with Intellij IDEA 12. I already tried advices: Embedding google maps android v2 in android Google Maps Android API v2 Authorization failure Unable instantiate android.gms.maps.MapFragment Google Maps Android API gives a NoClassDefFoundError and so on. But unfortunately that doesn't work for me. My configuration: 1) real device htc wildefire s, android 2.3.5 2) 3) AndroidManifest.xml: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="ru.ergeslab.TransportScheduleYaroslavl" (HowTos)
