NoClassDefFoundError with klio-mobile-dataservice on Android

I'm trying to implement klio's library, but I keep on getting this exception, even following the tutorial.

Here's the logcat:

Compiling goes well, so it looks like it finds classes during compile process... Can someone help me? :)

Solution

  • The problem is due to a change in how libraries are managed in ADT, starting from version 17.

    This is the solution, essentially:

    1. remove the KlioMobileDS project from your Java Build Path
    2. export it into .jar
    3. put that .jar into your project libs folder
