Android利用WebService查询手机号码归属地

MainActivity如下:

package cc.testwebservice;

import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import org.apache.http.HttpStatus;
import org.xmlpull.v1.XmlPullParser;
import android.os.Bundle;
import android.util.Xml;
import android.app.Activity;
/**
 * Demo描述:
 * 利用WebService查询手机号码归属地
 * 
 * 注意事项:
 * 在http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx?op=getMobileCodeInfo
 * 的SOAP 1.2中明确提示请求的设置:
 * POST /WebServices/MobileCodeWS.asmx HTTP/1.1
 * Host: webservice.webxml.com.cn
 * Content-Type: application/soap+xml; charset=utf-8
 * Content-Length: length
 * 即:
 * 请求方法:POST 采用HTTP协议 路径为/WebServices/MobileCodeWS.asmx
 * 主机名称:webservice.webxml.com.cn
 * 所以请求路径为http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx
 * 亦明确提示在POST请求时需要设置:
 * Content-Type和Content-Length字段及其值
 * 
 * 参考文档:
 * 1 http://www.webxml.com.cn/zh_cn/index.aspx
 * 2 http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx
 * 3 http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx?op=getMobileCodeInfo
 * 
 * 备注说明:
 * 该服务在少数时候,会访问失败403错误.
 * 多试几次即可
