Web Services是由企业发布的完成其特定商务需求的在线应用服务，其他公司或应用软件能够通过Internet来访问并使用这项在线服务。在这里我们使用soap协议往webservice发送信息，然后得到webservice服务器返回过来的信息，以此来查询手机号码的归属地信息。
Web Services有很多服务提供商，在这里我们使用www.webxml.com.cn的，如图：
点击进去，我们可以看到soap协议定义的内容。
接下来就是编写代码了。
package cn.mzba.service;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;

import org.xmlpull.v1.XmlPullParser;
import android.util.Xml;
public class MobileService {
public static String findAddress(String mobile) throws Exception {
InputStream is = MobileService.class.getClassLoader()
.getResourceAsStream("mobilesoap.xml");
byte[] data = StreamTool.readStream(is);
String xml = new String(data, "UTF-8");
String soap = xml.replaceAll("\\$mobile", mobile);
byte[] result = soap.getBytes("UTF-8");
String path = "http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx";
URL url = new URL(path);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();

conn.setConnectTimeout(5 * 1000);
conn.setRequestProperty("Content-Type",
"application/soap+xml; charset=utf-8");

OutputStream os = conn.getOutputStream();
os.write(result);
os.flush();
os.close();
