Android 4.0 API 中的 Dom 解析器

Question

我的问题是 Dom 解析器在 Android 4.0 中不起作用，但它在 2.2 上运行，如果我在我的 4.0 模拟器中运行该项目，那么下面一行不执行，这不会给出任何错误。

Document doc = db.parse(inStream);

以下是我的Java代码：-

public class TestParsingActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        StringBuffer sb = new StringBuffer();
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
                .permitAll().build();
        StrictMode.setThreadPolicy(policy);
        System.setProperty("http.proxySet", "true");
        System.setProperty("http.proxyHost", "192.168.1.220");
        System.setProperty("http.proxyPort", "315");
        String NAMESPACE = "Dipak";
        String SOAP_ACTION = "Dipak/Start";
        String METHOD_NAME = "Start";
        String url = "http://google.co.uk/Dip/service1.asmx";
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        PropertyInfo p = new PropertyInfo();
        String qry = "select Password from Profiles where ID = (select uid from userprofiles where name = 'Dipak')";
        p.setName("SQL");
        p.setValue(qry);
        request.addProperty(p);
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE httpTransport = new HttpTransportSE(url);
        httpTransport.debug = true;
        System.out.println("three**************");
        try {
            httpTransport.call(SOAP_ACTION, envelope);
            System.out.println("four**************");
            // SoapObject response=(SoapObject)envelope.bodyIn;
            SoapObject response = (SoapObject) envelope.getResponse();
            System.out.println("response =====>>>> "
                    + response.getProperty(0).toString());
            // SoapObject response=(SoapObject)envelope.getResponse();
            // SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
            System.out.println("success**************");
            sb.append(response);
            System.out.println("Data from Search Job =====>>>> "
                    + sb.toString());
            // return response.toString();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (XmlPullParserException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        try {
            DocumentBuilderFactory factory = DocumentBuilderFactory
                    .newInstance();
            DocumentBuilder db = factory.newDocumentBuilder();
            InputSource inStream = new InputSource();
            System.out.println("Data from try  =====>>>> " + sb.toString());
            inStream.setCharacterStream(new StringReader(sb.toString()));
            System.out
                    .println("Data from try  =====>>>>11111111111111111111111111111 ");
            Document doc = db.parse(inStream);
            System.out
                    .println("Data from try  =====>>>>22222222222222222222222222222 ");
            Element root = doc.getDocumentElement();
            String root1 = doc.getTextContent();
            System.out
                    .println("Value of root................................................................................"
                            + root);
            System.out
                    .println("Value of root1................................................................................"
                            + root1);
            System.out
                    .println("................................................................................5");
        } catch (Exception e) {
            // TODO: handle exception
        }
    }
}

任何帮助将不胜感激，对不起我的英语沟通不好。

你为什么不使用

response.getPropertyAsString(index);

或

response.getPropertyAsString("PROPERTY_NAME");

？

但是你仍然想使用 Dom 解析器，你可以使用 HttpTransportSE.responseDump 来获取 XML 格式的响应，并尝试解析 XML 而不是 ksaop2 的响应格式。
