Android 在 android 4 或更高版本中出现错误 Ksoap

Question

我的应用程序可以毫无问题地在 android 2.* 中运行，并且可以正确使用 KSoap 模块。但在 Android 4 或更高版本中安装应用程序后，我收到此错误：

627-627/ir.tsms E/AndroidRuntime﹕ FATAL EXCEPTION: main

我的WSDLHEPLER 是：

public class WSDLHelper {
    public static String call(SoapObject request) throws TException {
        String result;

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

        AndroidHttpTransport transport = new AndroidHttpTransport(Strings.URL_TSMS);
        transport.debug = true;

        try {

            /*  GETTING ERROR IN BELOW LINE  */
            transport.call(Strings.URL_TSMS + request.getName(), envelope);
            result = envelope.getResponse().toString();
        } catch (IOException ex) {
            Log.e("" , ex.getMessage());
            throw new TException(PublicErrorList.NOT_EXIST_ERROR_DETAIL);
        } catch (XmlPullParserException ex) {
            Log.e("" , ex.getMessage());
            throw new TException(PublicErrorList.NOT_EXIST_ERROR_DETAIL);
        }
        if (result.equals(String.valueOf(Integers.CODE_USER_PASS_FALSE)))
            throw new TException(PublicErrorList.USERNAME_PASSWORD_ERROR);

        return result;
    }

    public static String convert1(String str) {
        return str.substring(1, str.length() - 1);
    }

    public static String[] convert2(String str) {
        return str.split(", ");
    }

    public static String[] convert3(String str) {
        return str.split(",");
    }

}

在 android 2.2,3,3.* 中测试后没有问题。我不知道为什么这个模块不能在 android 4 中运行。请帮助我。谢谢

我的Ksoap 是：

ksoap2-android-assembly-2.4-jar-with-dependencies.jar

Answer 1

如果其他答案不起作用，请在您的 onCreate 方法中尝试此操作，

    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);

Answer 2

LogCat 告诉你出了什么问题：

FATAL EXCEPTION: main
android.os.NetworkOnMainThreadException

您在 MainThread 上联网，在 Android 3.0 及更高版本中，您必须在后台线程上进行联网。

编辑：这只是一个例子，它可能包含错误！

public class WSDLHelper  extends AsyncTask<String, String, String>{

private static String SOAP_ACTION = "http://tempuri.org/***";
//private static String SOAP_ACTION = "http://tempuri.org/***";
private static String NAMESPACE = "http://tempuri.org/";
private static String METHOD_NAME = "yourMethodName";
private String Url;

private Context context;

public WSDLHelper()
{

}

public WSDLHelper(Context context)
{
    this.context = context;
}


@Override
public void onProgressUpdate(String... data)
{
}

@Override
protected String doInBackground(String... uri) 
{
        publishProgress("prepare sending");
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);     


        request.addProperty("YourKey",Key);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

        new MarshalDate().register(envelope);

        envelope.setOutputSoapObject(request);
        envelope.dotNet = true;
        envelope.implicitTypes= false;

        try {
            HttpTransportSE androidHttpTransport = new HttpTransportSE(url);
            androidHttpTransport.call(SOAP_ACTION, envelope);
            // Get the SoapResult from the envelope body.
            SoapObject result = (SoapObject)envelope.bodyIn;
            String Test = result.toString();
            String Test1 = result.getProperty(0).toString();
            publishProgress("data accepted - " + result.getProperty(0).toString());
            return result.getProperty(0).toString();


            } 
        catch (Exception e) {
            return null;
            }

}

@Override
protected void onPostExecute(String result) {

    super.onPostExecute(result);

    if("OK".equals(result) )
    {
        // Do What you Want
    }
    else
    {
    }
}

}
