NoClassDefFoundError with external jar

Question

I know several posts already exist about this issue but I spent days to find out what's wrong and I still get this error, yet I followed all steps found on the web.

I'm only trying to add this jar to my project: https://github.com/jgilfelt/android-mapviewballoons/

I put it into libs folder with others jar such as admob... It compiles, then I can start the MapActivity related to the jar (the code came from the download above so this is original code) and when I tap on a marker on the map, the app crashes and here is what I get:

I hope someone could help me.
