android客户端开发调用webservice是出现错误

HttpTransportSE对象se.call(null,envelope);不能执行，导致activity直接stop
class MyButtonListener implements OnClickListener{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//调用方法

            int num1 = 1;
            int num2 = 2;

String wsdlUrl = "http://10.3.9.1:8080/TestPort/doAddPort";
String webMethod = "Add";
String nameSpace = "http://test.com/";
String soapAction = nameSpace+webMethod;

            SoapObject request = new SoapObject(nameSpace,webMethod);
            request.addProperty("a", num1);
            request.addProperty("b", num2);

            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.bodyOut = request;

            HttpTransportSE se = new HttpTransportSE(wsdlUrl);
            try {
                se.call(soapAction,envelope);
                System.out.println("你好 手机话费了快速点击封id是否");
                if(envelope.getResponse()!= null){
                    Object result = envelope.getResponse();
                    Toast.makeText(MainActivity.this, "结果为："+result, 2).show();     
                }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (XmlPullParserException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
    }

se.call(soapAction,envelope);里面写null或者soapAction都输不出“你好 手机话费了快速点击封id是否”

第一最好能在子线程中调用se.call(soapAction,envelope);
第二可能是因为你的开发环境没有搭好，
第三可能是你没有加入网络应用权限
第四在MainIFest.xml中要取消对SDK版本的限制规定
具体可以参考我的博客
