Question

我正在尝试使用ksaop2来使用webservice方法。

这是代码

公共类CityData扩展了AsyncTask {

    @Override
    protected void onPostExecute(String result) {
        // TODO Auto-generated method stub
        dialog.dismiss();
        try {
            if (!lstresponse.isEmpty()) {
                lstresult.addAll(lstresponse);
                lstcities.setAdapter(CustAdapter);
            }
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            Toast.makeText(LocationbyCities.this, "No net connection/very weak signal",
                    Toast.LENGTH_SHORT).show();
            finish();
        }
    }

    @Override
    protected String doInBackground(Integer... params) {
        // TODO Auto-generated method stub

        SendRequesttoServer();

        return "1";
    }

    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        dialog = new ProgressDialog(LocationbyCities.this);
        dialog.setMessage("Please Wait...");
        dialog.setIndeterminate(true);
        dialog.setCancelable(false);
        dialog.show();

    }

}

public void SendRequesttoServer() {

    try {

        SOAP_ACTION = NAMESPACE + METHOD;

        SoapObject request = new SoapObject(NAMESPACE, METHOD);

        SoapSerializationEnvelope res = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        res.dotNet = true;
        res.setOutputSoapObject(request);

        HttpTransportSE call = new HttpTransportSE(url);

        SoapPrimitive result;
        call.call(SOAP_ACTION, res);
        result = (SoapPrimitive) res.getResponse();
        ParseLocations Objparsecities = new ParseLocations(
                new ByteArrayInputStream(result.toString()
                        .getBytes("UTF-8")));
        lstresponse = Objparsecities.parse();

        System.out.println(lstresponse);

    } catch (SoapFault e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (XmlPullParserException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

它在模拟器上工作正常，但当我尝试在我的设备上运行时，我收到以下错误

我能知道这是什么错误吗？

现在我注意到，如果它们的信号很弱，就会发生这种错误。否则它工作正常。我也正在检查网络状态。我仍然得到这个错误。我该如何解决？

感谢：）

尝试使用方法时出现xmlpullparser异常
