Exception when using ksoap2 library for Android

I am using Ksoap2 version 2.5.4 in my Android Android project with maven support. Any reference to specific Ksoap classes throws this exception.

a line of code calling this

 SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

Could not find help related to this on SO or other forums. It seems pretty straight forward. Can someone tell me what is missing, and how can I make an android, use the library at runtime.

  • In your build path, clear all libraries (jar files).
  • In the main directory of the project, create a folder and name it "libs" (not "Lib").
  • Now Eclipse ADT Plugin will add your jar files to create the path.
  • Clean and create a project if necessary.
  • Happy coding

I had the same problem. I added a ZIP file instead of a jar file to an external library, you only need to add the JAR file.
