Unable to convert classes into dex format.

Question

I get the following error when I try to export out a build for android. I have done this 1000 times without a error. I uninstalled unity 3d and the SDKs and reinstalled everything. Any ideas?

I had the same error message and I upgraded my Java 1.7 to Java 1.8, then under external tools setting of Unity, added Java JDK 8 folder and the problem solved.

Some of your third party external libraries may be built by java 1.8 and unity cannot integrate them with your other java codes to be compiled with 1.7 IMHO.

Yes! problem solved. Note, it must be the 32 bits version.

Thanks for the solution, firatercis! I upgraded to Java 1.8 and re-started Unity and pointed the JD$$anonymous$$ in preferences to the new 1.8 directory and recompiled and Voila!!! I now have my first test app loaded onto my Galaxy S4 test phone! Thanks again!!

An already added error probably means something is being referenced more than once in your project setup.

SOLVED ANOTHER INNER ISSUE

I was also facing the same issue when I use Admob and Google Analytics. I have searched for same .jar file but my project was not containing any similar *.jar file. So after searching a lot I found the solution for my problem here.

The problem for me was with class named "Command$1.class" and "Command.class", these both class were already added while compiling and was being added again due to another .jar file which also have the same class files. So what I do is I open the libGoogleAnalyticsServices.jar through WinRAR and delete both class files and then I try to build and build was SUCCESSFUL.

You can figure out what class files are causing problem for you, and can delete it. But DO REMEMBER TO KEEP THE BACKUP OF THE .JAR FILE FIRST. ;)

Great answer Hardik$$anonymous$$aru2001, that solved the problem! Thank you very much! :) To anyone who's guessing how to create a new .jar file, here's a good tutorial: http://www.wikihow.com/Create-JAR-File

I had the same problem when both the plugins for Stan's Assets and Unity IAP were used.

In the case of plugins where you can enable or disable libraries, choosing the right ones to disable could help. This was what I did with Stan's Assets' Ultimate $$anonymous$$obile Settings, and the error went away.

Thanks!

This solves the issue. In my case Support v4 was also inside the facebook plugin. Console details will give the clue.
