Android Call WebService Instance Analysis _android

The example in this article describes how Android invokes WebService. Share to everyone for your reference. Specifically as follows:

WebService is a remote calling standard based on SOAP protocol, which can integrate different operating system platform, different languages and different technologies into one webservice. There is no library to invoke WebService in the Android SDK, so you need to use a Third-party SDK to invoke WebService. The PC version of the WebService client library is very rich, such as AXIS2,CXF, but these packages are too big for the Android system and may not be easy to migrate to the Android system. As a result, these development packages are not within our scope of consideration. Suitable for mobile phone WebService Client SDK has some, more commonly used to have KSOAP2, can download from http://code.google.com/p/ksoap2-android/downloads/list , copy the downloaded Ksoap2-android-assembly-2.4-jar-with-dependencies.jar package into the Lib directory of the Eclipse Project, and, of course, in other directories. This jar package is also referenced in the Eclipse project.

The Java code is as follows:
