I am creating a jar file where i did right click on project name then export>java>Jar file and then i checked on export generated class files and resources by selecting only src folder files and classpath and .project file.

This jar file i tried to use in another android project and i am getting this above

Unable to execute dex: Multiple dex files define com/example/projectname/xyzClass

So i followed this link here and unchecked my jar in order and export of buildpath and if i do so i am getting another error java.lang.NoClassDefFoundError: com.example.xyzClass

I have no idea why i am getting `Unable to execute dex: Multiple dex files define' error.

And here is the screenshot of order and export of my project where i am using my servicedemonew2.jar file.enter image description here

I would be glad if someone assist me with this why and when do we get this above error.

After seen your screenshot you need to uncheck your Android Dependencies and servicedemonew2.jar checkbox. Android Private Libraries will be remain checkable.

    Solution:

    ` as an answer should contain a possible solution which would make it redundant. A good programmer prevents redundancy!     – WarrenFaith Nov 26 '14 at 12:26
  • Piyush still i haven't found a solution. If i uncheck those two then i am getting NoClassDefFoundError exception. – Naveen Kumar Nov 26 '14 at 12:30
  • Is Android Private Libraries checked?? – Piyush Nov 26 '14 at 12:30
  • Yes it is checked as you said. – Naveen Kumar Nov 26 '14 at 12:31
  • Strange before some day i got same issue and solved this way. Do one thing just uncheck Android Dependencies and other both will checkable. And finally clean your project and run it – Piyush Nov 26 '14 at 12:33
  • I tried adding the servicedemonew2.jar in libs folder also and checked private libraries and servicedemonew2.jar in order and export and tried and i am getting Unable to exec: Multiple dex file error. And if i delete jar from libs folder and try same then i get NoClassDefFoundError exception. – Naveen Kumar Nov 26 '14 at 12:44
