I'm a newbie in android. I try a project on the used Nutiteq maps SDK on Github, but I made some errors:
in class MyMapEventListener error UTFGridRasterTileLayer,class CartoDBTorqueActivity error TorqueTileLayer, class CartoDBVectorTileActivity error CartoCSSStyleSet, class OfflineRoutingActivity error NutiteqOnlineRoutingService.
From your own comment, I can see you're using Eclipse, however, that is an Android Studio project. The problem could lie there.
Dependencies are downloaded via Gradle, but Eclipse's default is Ant. Have you tried Gradle Eclipse (https://gradle.org/eclipse/) or Android Studio?
Additionally, Nutiteq SDK 3 is old and won't be supported for very long. You should check out the new version, 4.0.0, CartoMobileSDK
