You should specify that the jar must be exported when building apk: in "Java Build Path" > "Order and Export" tab, fill the checkbox corresponding to your jar.

did you try cleaning your project after doing it? – sdabet Aug 30 '12 at 14:41
s i did and have run it.Wait i will let you know what all i have selected in the order and export tab – Rajeev Aug 30 '12 at 14:44
YEs it is working now after i did multiple cleans.But the APP doesnt seem to connect to the external system.Any idea why?? – Rajeev Aug 30 '12 at 14:48
It's probably a different problem now... Try to identify it and post a new question (with log traces) if necessary – sdabet Aug 30 '12 at 14:53
