Unable to convert classes to dex format - Android issue

I've been wracking my brain on this issue, never had it before. Tried so many different things. I am on a mac, attempting to deploy an Android version of our app. I keep getting this error:

Error building Player: CommandInvokationFailure: Unable to convert classes into dex format. See the Console for details.
/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin/java -Xmx1024M -Dcom.android.sdkmanager.toolsdir="/Users/ixikos/adt/adt-bundle-mac-x86_64-20130729/sdk/tools" -Dfile.encoding=UTF8 -jar "/Applications/Unity/Unity.app/Contents/BuildTargetTools/AndroidPlayer/sdktools.jar" -

I've tried installing different versions of the android sdk (18, 17, 16, 15, ... 6)
Deleting and installing different versions of jdk.

Any thoughts or experiences would be welcome.

 

I have the same issue. Any help would be more than welcome.
Or if you solved it yourself please post how.

 

We are having this issue as well, and cannot make Android builds anymore because of it. Any help would be great.

 

Just started using a hackintosh and now I can't build any more Android builds due to the same issue. Can anyone shed some light on this?

 

There is extra info in the console:

I'm getting the same error and the exact same console output as DreamEnder. I updated to the latest Unity this morning so I suspect that's related. Has anyone found a solution?

 

My issue was actually related to having duplicate files. Well not really duplicates, but I had 2 adMob sdk packages (different versions), that were getting into conflict. After deleting the older one, everything was fixed. Are you using any 3rd party SDK's or something similar, if so, try removing them if possible and see if the issue persists. Try to find out which part of the code is causing this to happen. You could ultimately try to compile an empty project just for testing.

 

we are having the same issue, Anyone able to solve this, please help.

 

hey all. I come across this same error sometimes. Its when i import a new package and then two of the same jar files in the project. For example, I had 2 versions of the heyzap.jar file. I just deleted the old version from the project and it was solved. It also happened with the admob sdk (contains the googleAds jar), and the billing sdk for google play. Sometimes the jar file versions have different names so watch out for that. I usually take a screenshot of the package files before I do the import so I can go back and look it over. I also always always always do a back up of the project before importing 3rd party plugins - saves a lot of headaches.

hope this helps
Martin

 

Getting the same error after updating to 4.3 and trying to use the OUYA plugin

I'm not sure what the posters above are talking about in regards to deleting duplicate files. I went into my android SDK and uninstalled all but one version (16)

Here is my error message:

Same problem here... Did you get an solution?

 

I deleted all the hidden Mac files called "._something" and it worked again.

 

Happened to me when I upgraded to 4.3. I got rid of it by doing a Reimport All.

 

I have two jars with the same classes in Plugins/Android. After removing one of them build is running again.

 

When I ran into this recently, it seems to be caused by using a JAR which references classes.jar for android. It seems that I must reference the AndroidDevelopmentPlayer version when building my JAR if I want to build a development player the AndroidPlayer version if I'm not. I guess this kinda makes sense, but it also seems a little weird, since it's just a reference.

 

I found the solution was also in the Plugins\Android folder. With inspection I found the issue and was able to build to device. whooo hoo.

 

Hello SkyboardSoftware ,

Can you please tell me how you solve this problem ?

 

My problem was I had two In-app billing plugins. I got rid of one entirely and my problem was solved!

 

@sandiprudani others who haven't solved this

I had a very similar problem as this and my issue was that their were duplicate files interfering with each other in the Plugins/Android folder. Unity has the ability to check file depth in this folder, meaning that if you have a Plugins/Android/lib folder and a Plugins/Android/SomePlugin/lib folder, Unity will merge them during the build process. I had recently updated a Facebook plugin and it had created the folder: Plugins/Android/FacebookPlugin. In this folder, there was a /lib folder and a /res folder. Because the older version of my Facebook plugin simply added these files to the normal Plugins/Android/res and Plugins/Android/lib I now had two lib folders and two res folders, the newest of which just and extra folder level deep. Unity still recognized both folders and merged them, but two files were identical, so it failed on the conflict. Simply deleting my old duplicates fixed my issue.

Hope this helped!

 

I had the same problem when i had imported the GooglePlayServices plugin in a project where were already present a third party plugin for AdMob (in my case). I had to delete the third party plugin to make the build, but as StevenSauer said it must be an issue relative to duplicate files.
Here the link for a workaround for the GooglePlayServices, i know that probably you are not using this one but maybe you can use the same "technic"
https://github.com/playgameservices/play-games-plugin-for-unity/issues/6

Hope it could help

 

im having this problem with prime31 google play game services here is the output, does anyone have a solution to this problem, it a new project with just 1 prime31 package with the realtime multiplayer demo scene, and it wont build

That's the answer.
For example,like install android native plugin aftter admob plugin.
That's not a conflict,very lucky.

 

I have same problem after importing android native plugin.

is there anyone to solve this problem? please help me...

 

I solve this problem.
first, I remove all files in plugins folder,

and I attached plugin file one by one that I need.

then, I success to build my app

So if you have this problem, that should be coupled plugin module,

however it is too hard to find coupled module,

so, remove all files in plugin folder, and add what you need.

ps. back up plugin file before you remove

 

Same here.
Plugin kill and imported one more time all packages

 

I got this error by updating older plugins in my project.

But I SOLVED it by removing all my plugins and importing them again.

 

I think that I have universal way:
It shows the problem: "java.lang.IllegalArgumentException: already added: ......" and name of the class (for example: IInAppBillingService$Stub$Proxy)
Using any utility (like grep) or your FileManager' feature to search inside of files just search this class (IInAppBillingService) in all files and remove all extra files (.jar) that contain it. "There can be only one"

 

For me, I had the file "android-support-v4" twice, I deleted one and it's working fine now.

 

Delete unrelated file from Android/libs directory, only keep Android - support - v4 files

My problem is resolved

You can try.

 

Another possibility is an update from a 3rd party SDK. There is jar upgrade but not replaced. E.g., ver1.1.1.jar and ver1.1.2.jar both present in the project. You may think you already removed the old from from your version control system. But you should also check: unity/Temp/StagingArea/plugins
for any residual files there.

 

Thank you very much, I saved a lot of time.

 

I had this problem, I didn't and it appeared only once, I tried to build again and it worked fine without changing anything, I am sure it is a file duplication issue tho.

 

Just had the same problem, and as mentions above with new heyzap plugin. To solve it I just removed old jar in Plugins/Android folder.

 

I had installed FB Unity, so I decided to install Prime31. Well, the error show up.
After many hours, the file with error is bolt.jar. I removed and removed duplicated android-support and can build again.

 

Hi,
I deleted the android-support-v4 lib and it solved the issue. Thanks !

 

I think the easiest way to solve this is to do a search for all "*.jar" files in your project folder. Then simply delete the duplicates. Solved it for me.

 

You are right! However, sometimes there are 2 jar files with different names, but inside those jars there are classes with the same names. This can cause the problem as well.

 

This exceptions will also pop up if you'll update to new version of *.jar library just by copying it with Finder/Explorer.
Problem is with corresponding .meta file that don't get regenerated. To fix this: just remove old .meta file for .jar library.

 

Hi,

Anyone Please give solution for these

I solved THIS PROBLEM in my case. The Problem was conflicting InAppBillingLibrary in project.
I was trying all available In-app billing librares available
First I imported Soomla Packages and was able to BUILD.
Then I tried to import OPENIAB packages and when TRIED ti build this ERROR CAME.
SO, I just REMOVED all SOOMLA PACKAGE CONTENTS keeping only OPENIAB package contents from my unity project and all is fine now.

 

This happens just because of duplicate jar files. try removing the duplicates. it will work.

 

You are right. However, sometimes there are 2 jar files with different names, but inside those jars there are classes with the same names. This can cause the problem as well.

 

@Kurius Exactly what I went through when integrating Twitters Fabric last night . You explained straight to the exact problem. (bow)

 

Can anyone explain where the .jar files would be i am experiencing the same issues but cannot find the jar files.

 

Error building Player: CommandInvokationFailure: Unable to convert classes into dex format. See the Console for details.


I solved this problem by simply changing the sdk path to a new adt bundle that contains sdk (this sdk folder was actually working for one of my friend ).

 

Had the same issue, solved by removing duplicate jar files under Plugins/Android/**

 

its spent me lot's of time. and i decide to give up. i try it so many times & ways just one jar file.

 

I had this issue and it was caused by Facebook SDK... I recently updated it... and it was using a plugin called "bolts".. the new version added "bolts-android-1.1.2.jar", thus I had this library twice.. just deleted "bolts" and project is compiling again.

 

I Got Mine! I just mistype the capital.
# in the playersetting
com/facebook/GameName(should be)
com/Facebook/GameName(me)

 

I had the same error "Unable to convert classes into dex format." that was introduced while implementing the Soomla Profile plugin.
Somewhere along the way the "AndroidProfile" and "UnityAndroidProfile" were duplicated to "AndroidProfile 1" and "UnityAndroidProfile 1". Removing the dups took care of the errors.
