Could not find class 'org.ksoap2.serialization.SoapObject'

When you are running an Android app which uses the ksoap2 as external library some times you may face this unfortunately stopped error.

To solve this problem what you need to do is
Right click on your project select Properties >> Java Build Path and click Order and Export tab tick the check box before to the ksoap2 imported jar and click OK.

Then the error should be solved. :)
If you are still having the same problem clean the project and delete previously installed app from emulator or device and reinstall.
