Right click on the Project Name
Select Build Path -> Configure Build Path
In Java Build Path, go to the tab Order and Export

Uncheck your .jar library

Only sometimes: In Order and Export tab I did not have any jar library there, so I have unchecked Android Private Libraries item. Now my project is running.

check this

I think you are using both jar file and SDK of third party library. Delete jar from libs folder or remove that SDK from your project

Are you using SDK of this library too?? – Avinash Kumar Pankaj Nov 06 '14 at 12:32
