Error Exporting Vuforia Unity Project into Eclipse

I'm using the Unity's Vuforia Extension, and created a AR scene. But while exporting to Android, a pop up came and SDK outdated, but my SDK is the latest.
I clicked continue and imported the project into Eclipse.
But while trying to run the project, it doesn't launch saying the projects have errors.
I tried cleaning and running again, it shows me this in the Console tab:
[2015-02-14 10:06:34 - QCARPlayerNativeActivity] Dx
trouble writing output: already prepared
[2015-02-14 10:06:34 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/qualcomm/QCARUnityPlayer/BuildConfig;
[2015-02-14 10:06:34 - QCARPlayerNativeActivity] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/qualcomm/QCARUnityPlayer/BuildConfig;
Any ideas anyone?

In the export window, I didn't click select the scene before clicking export.
Problem solved.

[2014-02-12 16:05:53 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/readystatesoftware/sqliteasset/SQLiteAssetException; [2014-02-12 16:05:53 - AClickCell_Orion] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/readystatesoftware/sqliteasset/SQLiteAssetException;

Go to lib folder and remove or delete android-support-v4 jar file. And clean and run. It will work.

Go to Project Properties > Java Build Path and under Add Libraries Tab, remove Android Dependencies. Then right click on project, go to Android Tools and click Add supported Libraries. See if that helps

Your project has two copies of the sqliteasset helper library. Remove one of them.

Project File Import

I recently bought a new MacBook Pro and imported a couple of project files from the old laptop. Today I attempted to run an app on my device, but the project would not show in the run configurations window.I imported the file again, and got the project to show, but now I get the following error when trying to run on my device:
[2014-01-06 21:04:04 - Dex Loader] Unable to execute dex: Multiple dex files define Landroid/support/v4/app/Watson$OnCreateOptionsMenuListener;
[2014-01-06 21:04:04 - Verbatim] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Landroid/support/v4/app/Watson$OnCreateOptionsMenuListener;
I believe I made a mistake in the way I transferred files over from the old laptop, as well as how I imported the project into the ADT. I have no clue what the above error means and have no idea how to begin fixing it. Perhaps someone can enlighten me. Thanks!

Seems like you have multiple versions of the same projects. Dex files are what really runs Android (converted from Java, thankfully done automatically)
Try deleting all of the same projects in the adt (make sure to back that one project up just in case). Try going to the workspace folder and make sure to have only one version of it, then import it. Hope it helps

DX Error when running Android Studio project

I am trying to set up my Android Studio project with al its dependencies. But when i try to run my project i get the following error messages:
Android Dex: [AndroidVI] Unable to execute DX
Android Dex: [AndroidVI] com.android.dx.util.DexException: Multiple dex files define Lcom/androidquery/util/Constants;
Can anybody help me with this

Check Whether You added Same jar files more than once.
If yes,Remove any one of them from libs folder and clean your project.

Check if Your Proguard is running or not.

Android: Dex conversion failed while importing

I got an error while i import an android project from one workspace location to another in eclipse.
I'm using Google_admob in my project to display ads..I does't have any errors and it works well in my old workspace.
Eclipse Version : Indigo Service Release 2
Android-Project Version : Android 4.0.3
Error states :
[2012-12-03 12:02:27 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/google/ads/Ad;
Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/google/ads/Ad;

i found my problem.
I actually import my lib jar file in libs_folder and also in project_libraries(External Jar)..So 2 times dex file has created in bin/dexedLibs/ ..Now i deleted one jar file from one location ..
now its working
Thanks for your support geeks..

My problem was resolved after cleaning up some directories and files left over from the previous versions of the tools. ADT Rev 14 changes where binaries are stored. I deleted the entire bin directory, restarted Eclipse and cleaned the build and forced a rebuild. That seemed to do the trick initially but the problem came back after the next run.
I finally discovered that my bin directory was included in the project build path. I excluded bin from the build path and repeated the steps above. This resolved my problem.
