I am trying to access the magento web service from an android client. It should return a session identifier. I already made this uing java client using apache and I managed to call the method. How can I get xmlpullparser exception when trying with android client as: 10-24 15: 25: 44.409: WARN / System.err (277): org.xmlpull.v1.XmlPullParserException: expected: START_TAG { http: //www.w3 .org / 2001/12 / soap-envelope } Envelope (position: START_TAG @ 2: 327 in java.io.InputStreamReader@44ee2268 )
Well, this is my wsdl file from which I am trying to access the login method: 
my java code is:
public class DeviceClientActivity extends Activity {
private static final String NAMESPACE = "urn:Magento";
private static final String URL = "http://xxx.xxx.xx.xxx/magento/index.php/api/v2_soap?wsdl";
private static final String METHOD_NAME = "login";
private static final String SOAP_ACTION ="urn:Mage_Api_Model_Server_V2_HandlerAction";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log
.d("WS",
"--------------------- Webservice Part Begins ---------------------");
Log.d("WS", "1. SoapObject Construction");
SoapObject objsoap=new SoapObject(NAMESPACE, METHOD_NAME);
objsoap.addProperty( " ", "alokxxxx" ); objsoap.addProperty( "apiKey", "xxxxxx" );
Log.d( "WS", " SOAP Object End!!!" );
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
Log.d("WS", "2. Envelop Created");
envelope.setOutputSoapObject(objsoap);
Log.d("WS", "3. Request Into Envelop");
AndroidHttpTransport httpTransport = new AndroidHttpTransport(URL);
httpTransport.debug = true;
Log.d("WS", "5. Transport Level to True");
try {
httpTransport.call(SOAP_ACTION, envelope);
// WARN/System.err(277): org.xmlpull.v1.XmlPullParserException: : START_TAG {http://www.w3.org/2001/12/soap-envelope} (: START_TAG @2: 327 java.io.InputStreamReader@44ee2268)
Log.d("WS", "6. httpTransport.call");
if (envelope != null)
{
SoapObject loresponse = (SoapObject) envelope.getResponse();
SoapObject logObject = (SoapObject)loresponse.getProperty("sessionId");
Log.d("WS", "logObject: "+logObject);
}
else
{
Log.d("WS", "Response Envelop Error");
}
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
}
}
}
