Error connecting android app to Google Cloud Endpoints: could not find class

I have built an API with Google Cloud Endpoints and I am trying to connect to it writing an Android application. I followed the following tutorial:

https://developers.google.com/appengine/docs/java/endpoints/consume_android

So, I added the content of the jar on my "src" folder, I copied the listed libraries to lib and I added the code. When I tried to start the application, it crashed with the following error: 

        02-26 12:19:52.874: E/dalvikvm(17558): Could not find class 
    'com.google.api.services.utenteendpoint.Utenteendpoint$Builder', referenced from method

Do you know the possible cause of this error?

EDIT: I also found this before the log reported above

02-26 16:51:57.780: W/dalvikvm(1230): Unable to resolve superclass of Lcom/google/api/services/utenteendpoint/Utenteendpoint$Builder; (20)

Add the sources.jar file also to libs folder of your android project, just like the other jar files.

Thanks Raffo for finding the typo error in my earlier post
