java - Error when building apk - "Multiple dex files define Lcom/google/ads/Ad"

Question

I've been tearing my hair out over this one, for the past 3 hours I've been trying to fix it but have been unable to. I've created an android app and I'm ready to put it on the android market but I get this error when trying to export to an apk.

Unable to execute dex: Multiple dex files define Lcom/google/ads/Ad;

I've read a bunch on the problem and tried quite a few solutions but nothing has seemed to help. I've cleaned and rebuilt, I've delete the bin folder, I've made sure that the bin folder is excluded build path. Nothing's worked. If anyone could help me I would really appreciate it.

Answer 1

Untick the admob jar file in the "order and export" part of the "configure build path".
