I have tried lots of combinations inside buildpath, adding the source project, adding de core.jar (named zxing-1.7.jar in my project), addiing it as external library…but when i don’t get this problem at the bottom, then i get a dalvik format error, saying Lcom/zxing/android: already added.

I have also tried to put the .jar inside a folder called libs, but none working, checking and unchecking it on build path configs.

here’s an image of my current Build Path order, http://postimage.org/image/f496ukwkf/ , but i tried with lots of different combinations, and none of them worked.

Thanks, i need to get it working, please.

    You are trying to include code from android/ in your project. You’re not intended to do this, and you haven’t set it up correctly either. Integrating by Intent (http://code.google.com/p/zxing/wiki/ScanningViaIntent) is far easier if you are new to this. No library code to mess with.
