I'm using Ksoap2 version 2.5.4 in my maven enabled android Project. Any reference to the Ksoap specific classes is throwing this exception

the line of code causing this is 

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

Couldn't find any help related to this on SO or other forums. This seems pretty straight forward. Can any one tell me whats missing and how I can make android use the library at run time.

  • In your build path clear all libraries (jar files).
  • In project's main directory create a folder and named it "libs" (not "lib").
  • Now Eclipse ADT Plugin will add your jar files to build path.
  • Clean & Build your project if necessary.
  • Happy coding
