I don't know if this is appropriate to post this here but i hope you could help me anyway. This morning i was trying to export my libgdx project to android and run it , but i couldn't make it works. At start it raised this exception java.lang.NoClassDefFoundError: com.esotericsoftware.spine.SkeletonData . Then i checked all projects needed in order & export ( main libraries ) but it didn't help... what am i missing? :bang:
