GetResponse from SOAP webservices In Android

I want get the response from a SAP SOAP Web service but I get an Exception.

I'm using the following code:

package com.veee.pack;
import java.io.IOException;
import android.app.Activity;
import android.os.Bundle;
import java.io.IOException;
import org.apache.http.client.HttpClient;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.params.BasicHttpParams;
import org.apache.http.params.HttpConnectionParams;
import org.apache.http.params.HttpParams;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.SoapFault;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.AndroidHttpTransport;
import org.ksoap2.transport.HttpTransportBasicAuth;
import org.ksoap2.transport.HttpTransportSE;
import org.w3c.dom.Element;
import org.xmlpull.v1.XmlPullParserException;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class WeservicesExampleActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        //getting these values from wsdl file
       //username and password appended as URL Parameters
         final String NAMESPACE = "urn:sap-com:document:sap:soap:functions:mc-style";
         final String URL = "http://*********:8000/sap/bc/srt/wsdl/srvc_14DAE9C8D79F1EE196F1FC6C6518A345/wsdl11/allinone/ws_policy/document?sap-client=800&sap-user******&sap-password=************";
         final String METHOD_NAME = "Z_GET_CUST_GEN";
         final String SOAP_ACTION = "urn:sap-com:document:sap:soap:functions:mc-style/Z_GET_CUST_GEN";

        SoapObject request =new SoapObject(NAMESPACE, METHOD_NAME);

        request.addProperty("Input", "1460");
        request.addProperty("Langu", "d");

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);

        envelope.setOutputSoapObject(request);

        HttpTransportSE httptransport=new HttpTransportSE(URL);
        httptransport.debug = true;
        try {

          //calling the services
         httptransport.call(SOAP_ACTION, envelope);

         Object result = (Object) envelope.getResponse();

        //getting the Response Here.

         System.out.println("Result" + result.toString());

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

When I debug the Application it terminates at

httptransport.call(SOAP_ACTION, envelope);

I ran some examples by using ksoap2 in android it is working fine. I got the following exception in my logcat:

04-24 12:19:17.935: WARN/System.err(1569): java.net.SocketTimeoutException
04-24 12:19:17.935: WARN/System.err(1569):     at org.ksoap2.transport.HttpTransportSE.call(HttpTransportSE.java:130)

Please give any suggestion to overcome this issue or send how can i make request and receive the response through XML in Android.

Thanks in advance.....

AVoid using SOAP in android.. because it is not recommended.

Use Restful webservices which is officialy suported by android. If your webservice provider is unable to provide Restful service,...bear with some problems like the app will not work some times and may not work in some of the android devices.

To get rid of problems with your ksoap2 impleentation play with multiple ksoap2 drivers, put the logic of network calls in a separate thread.

The call to httptransport.call(SOAP_ACTION, envelope); consumes huge memory, more time and hence avoid using this call in main thread. Try in a new create emulator and one of the devices. KSOAP2 works 20 to 50% of android devices. Some times it may not work in a device from a same manufacturer, for example it may work in HTC sense 2.3.4 and may not work in ver 2.3.5 of HTC Sense.

It is recommended to use Restful Webservices.

You can set the timeout limit manually by using ksoap2 library 2.5.2 with dependencies by using 

HttpTransportSE androidHttpTransport = new HttpTransportSE(URL,Time_Out);

A socketTimeoutException occurs when the socket cannot read or accept within a certain interval. You should always be prepared for something like this and use try/catch in your code to handle these situations.

To access web services in general; make sure your app has the android.permission.INTERNET in it's manifest and check that the web service can be reached from the emulator. You can use the code from this post to check if your service is reachable.
