Connecting to C# asp.net using Ksoap2 in Android

Question

I'm trying to connect to my asp web service and get the response using this codes. It gives no error but it's not connecting to my web service either. Can anyone point my mistake? thanks

public class MainActivity extends Activity {

    private static final String SOAP_ACTION = "http://tempuri.org/MyFirstWebMethod";
    private static final String OPERATION_NAME = "MyFirstWebMethod";
    private static final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";
    private static final String SOAP_ADDRESS = "http://10.0.2.2:1595/test.asmx";
    String name = "Test";
    String last = "Me";
    String result;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ((Button) findViewById(R.id.btngo)).setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub
                 SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE, OPERATION_NAME); 
                 request.addProperty("name", name);
                 request.addProperty("last", last);
                 SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
                 envelope.dotNet=true;
                 envelope.setOutputSoapObject(request); 
                 HttpTransportSE ht = new HttpTransportSE(SOAP_ADDRESS);
                 try {
                 ht.call(SOAP_ACTION, envelope);
                 SoapObject response  = (SoapObject)envelope.getResponse();

                 result = response.getProperty(1).toString();

                 } 
                 catch (Exception e) {
                 e.printStackTrace();
                 }   

                Toast.makeText(getBaseContext(), ""+result, Toast.LENGTH_LONG).show();
            }
        });


    }
}

this is what the log cat said

According to logs your problem not with ksoap. You are doing networking on UI thread which is forbidden by default on newer android versions.

Do u think webservice at "http://10.0.2.2:1595" will be accessible publicly ?(In my option NO). Try to host it on public IP and then try . Your code seems to be OK .
