Make a libs directory in your application package hierarchy.

Put external jar file in it,

Then Right Click on jar file -> Add to Build Path..

Clean your project and Run again..

Now im getting new error while installing it, [2012-07-20 19:25:00 - SimpleViewPager] Dx 1 error; aborting [2012-07-20 19:25:00 - SimpleViewPager] Conversion to Dalvik format failed with error 1. I tried cleaning and even restarted eclipse – Vins Jul 20 '12 at 13:55
The problem was i added external jar before and again i added in libs. So i deleted the project and created new one.Thanks for your help. This is the question i referred to http://stackoverflow.com/questions/2680827/conversion-to-dalvik-format-failed-with-error-1-on-external-jar – Vins Jul 20 '12 at 14:13
