Android project depends on java project

Question

I've been playing with a Java's Magento connector called magja (https://github.com/magja/magja) in a 'normal' Java project. And everything were working fine till this point.

After that, I started a simple Android application that would use the magja code to consume such information from Magento.

The question is: how should I configure the my Android project to deal with a 'normal' Java project (not a library)? This another project uses several xml files to configuration and Maven to deal with dependencies. How this impacts my Android App?

Thanks a lot!

EDITED

Actualy, I've already tried this approach (Android project unable to reference other project in eclipse), but always when the app tries to run the 'project B' (magja) code, it causes a
java.lang.NoClassDefFoundError: org.apache.commons.httpclient.params.HttpConnectionManagerParams

I believe it's related to some .jar files that magja uses. It looks like that I would solve the problem if I could share such library between the projects.
