Android的消费Dynamics NAV的SOAP Web服务 [英] Android Consuming Dynamics NAV SOAP Web Service
本文介绍了Android的消费Dynamics NAV的SOAP Web服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想建立一个对我的Android应用程序，以动态导航2013 R2与SOAP的Web服务连接。
I am trying to establish a connection for my android app to dynamics nav 2013 r2 with SOAP web service.
从来就尝试在不同的论坛发现了几个教程，但未能建立连接。
I´ve tried several tutorials found in different forums but failed to establish the connection.
NTLM是在NST启用。
NTLM is enabled on the NST.
这是在Java类从来就试过：
This is are the java classes I´ve tried:

The access to the web service works when I try to open the page with the android browser.
任何帮助将是AP preciated。
Any help would be appreciated.
推荐答案
好吧，我找到了一个解决方案。这里是谁需要连接到一个动态NAV（Navision的Web服务）。
Okay I found an solution. Here is the solution for everyone who needs to connect to an Dynamics NAV (Navision Web Service).
第1步 - >下载ksoap2-Android的组装XX.X-JAR与 - dependencies.jar的最后一个版本，它集成到应用中。
Step 1 --> Download the last version of ksoap2-android-assembly-xx.x-jar-with-dependencies.jar and integrate it in your app.
第2步 - >创建这2 Java类的NTLM身份验证
