    For an android app, I’d same issue with an external jar file. In my case the solution was to move the jar from “lib” folder to the android default “libs” folder.

    When the jar was in lib folder (was added to build path as well), while there are was no build issue in Eclipse, the app was giving ClassNotFoundException at runtime. Once I moved the jar to “libs” folder, the jar started appearing under “Android Dependencies” and app started working fine.

    These are some of the other discussions about the same topic.

3)http://stackoverflow.com/questions/2611105/how-to-specify-lib-folder-for-jars-when-using-android-generated-ant-build-file

    may this could help…!!!!!
