NoClassDefFoundError android flex ane extension

view full story

http://stackoverflow.com – I created a ane native extension for a flex application and I have a problem. My problem is that i get a NoClassDefFoundError from native java code. The class that is not found is in a third-party jar. I added the third-party jar as a lib file in eclipse, is also set on project build pats and is also set as exported resource. I think the problem is when i pack the final .jar file for the extension. I unpacked the .jar file and the third-party jar is there. (HowTos)
