Sometimes while trying to export an APK using Eclipse, it gives the error “Conversion to Dalvik format failed with error 1.” However meanwhile if you try to run the project normally on a debug device, it launches just fine. For example, this often happens when you try to make an APK out of a Cocos2d-x project.

This error is due to the crapball design of Eclipse (let’s pile more crap on a crap to increase functionality), but fortunately, there’s an easy solution to fix this problem: All you need to do to fix this problem is to disable automatic build from the Project menu, clean everything and retry exporting the APK.
