Unable to convert classes into dex format.

RandomCharacters · March 25, 2014, 1:30am

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?

==========================

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

See here for similar:

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.

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.

I reinstalled stan’s assets mobile ads sdk and it works fine now. Thanks

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

Check below thread:

I solved my issue by logging into unity and …by going onto services tap and turn the ads off. This will solved the issue in my case…

@shivu
I already use java 1.8 but how can i solve that problem

CoderVinod · March 28, 2018, 11:51am

SOLVED. While importing a plugin from Asset Store, i was importing the ‘Support’ files also(which were already present in my project). So after deleting them, the error is gone.
