Android - Creating SoapObject throws InvocationTargetException

Question

I am learning how to use Web services on a mobile platform (specifically Android) with KSOAP. However, I seem to be running into a problem when creating a SoapObject.

String NAMESPACE = "http://webservicesx.net/";
String METHOD_NAME = "ChangeMetricWeightUnit";
String SOAP_ACTION = NAMESPACE + METHOD_NAME;
String URL = "http://173.201.44.188/convertMetricWeight.asmx";

SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);

My code crashes on application start and debugging has shown that the SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME); throws an InvocationTargetException.

My LogCat is as follows:

From what I can tell from the LogCat, the compiler couldn't find the SoapObject class despite the fact that I imported the KSOAP.jar into the project.

May be the same problem with exception while using ksoap2 library for android question. Try this.

For some reason, simply surrounding the creation of the SOAP object with a try block seemed to work. – Jason L Jun 08 '12 at 13:49

I'm not exactly sure why this worked but surrounding SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME); in a try block like so:

try {
SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
...
}

resulted in my code compiling and executing properly. Not quite sure why simply surrounding it in a try block made it work so any clarification on that note would be nice.
