exception while using ksoap2 library for android


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.


Solution

    • 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
