本文介绍了一种在安卓应用中通过WebService获取国内航班信息的方法。利用SOAP协议，该应用可以实现航班信息的实时查询，并详细展示了关键代码及数据解析过程。

关键代码：

package com.example.service;

 public static SoapObject getResult(String endPoint, String methodName,
   String soapAction, String nameSpace, String[] pars, String[] vals) {
  // 创建 SoapObject 对象，指定命名空间和调用的方法
  SoapObject soapObject = new SoapObject(nameSpace, methodName);
  // 判断参数
  if (pars != null) {
   // 设置参数名和参数值
   for (int i = 0; i < pars.length; i++) {
    soapObject.addProperty(pars[i], vals[i]);
   }
  }
  // 生成SOAP请求信息,并指定SOAP的版本
  SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
    SoapEnvelope.VER11);
  // 申明调用的是 dotNet 开发的 WebService
  envelope.dotNet = true;// 相当于envelope.bodyOut=soapObject;
  // 将SoapObject 对象设置到请求信息中
  envelope.setOutputSoapObject(soapObject);
  // 传输协议对象，指定访问的webService地址
  HttpTransportSE transportSE = new HttpTransportSE(endPoint);

  }
  // 获得返回数据
  SoapObject object = (SoapObject) envelope.bodyIn;
  // 返回数据
  return object;
