Access C# .net web service in android
Question
How can I use .net web services using android?
My code is like this...
package Webservices.pck;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.widget.TextView;
import android.app.Activity;
import android.os.Bundle;
public class Webservices extends Activity
{
private static final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
private static final String METHOD_NAME = "HelloWorld";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://ipaddress/Service1.asmx";
//private Object resultRequestSOAP = null;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
try
{
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.debug = true;
envelope.dotNet = true;
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject resultRequestSOAP = (SoapObject)envelope.bodyIn;
String result = (String)resultRequestSOAP.getProperty(0).toString();
tv.setText(result);
this.setContentView(tv);
}
catch (Exception aE)
{
tv.setText(aE.toString());
this.setContentView(tv);
}
}
}
In this code I am using.
String URL = "http://ipaddress/Service1.asmx";
then error :-- org.xmlpull.v1.xmlPullParserException: expected:START_TAG {http://schemas.xmlsoap.org/soap/envelope/}Envelope(position:START_TAG<html>@1:6 in java.io.InputStreamReader@4375fda8)

You are accessing an html page and not a SOAP service. The parser Exception has already told you what's wrong.
You got data like this
<html><body>... </body></html>
while the page should return something like
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<YourFunctionToCall... />
</soapenv:Body>
</soapenv:Envelope>
Maybe you have a typo in your URL, or some kind of Authentication or some other kind of error, so that it returned an HTML error instead of the Soap Request/Response.
