android export dex failed error

Hi, i have been trying to figure out for days now why i cannot export qualcomm AR application from their standard package to my samsung galaxy 10.1 device without cause the following error:

Building DEX Failed!

C:\Softs Projects Documents\Unity3D\Unity3D_Android_XX6\Temp/StagingArea> java -Xmx1024M -Djava.ext.dirs="C:/Development/Android/android-sdk-windows\platform-tools/lib/" -jar "C:/Development/Android/android-sdk-windows\platform-tools/lib/dx.jar" --dex --verbose --output=bin/classes.dex bin/classes.jar plugins

For the very few forums that i read on this issue we need to have the latest java installed which it is.Otherwise there is not much to say if only that i can export standard android application with no AR features attached to it.

 

Can someone help.

Tks
