I would recommend synchronizing your tutorials and tools. Right now, that probably means switching to Eclipse. Android Studio is still an early-access previews. I don't recommend that newcomers to Android start with Android Studio, in part because of the struggles that you are encountering. Android Studio uses project structures set up for the new Gradle-based build system, which is different from what Eclipse uses. Plus, the wizards may generate different files, as you are seeing.
Now, if you can find a set of tutorials that happen to be based on Android Studio, and you want to go that route, that's your call. But a newcomer to Android trying to translate instructions for Eclipse into instructions for Android Studio is likely to get frustrated. So, if your tutorials are for Eclipse, I would recommend using Eclipse.
