的code线引起，这是

the line of code causing this is

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

找不到与此相关的SO或其他论坛的任何帮助。这似乎是pretty的直线前进。任何人能告诉我什么失踪，我怎么可以让Android应用在运行时库。

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.

推荐答案

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
