                request.addProperty("password", password.getText().toString());
                SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                        SoapEnvelope.VER11);
                envelope.setOutputSoapObject(request);
                envelope.dotNet = true;
                try {

                    HttpTransportSE androidHttpTransport = new HttpTransportSE(
                            URL);
                    androidHttpTransport.call(SOAP_ACTION, envelope);
                    SoapObject result = (SoapObject) envelope.bodyIn;
                    txt.setText("upto result");
                    if (result != null) {
                        String h = String.valueOf(result.getProperty(0));
                        txt.setText(h);
                        if (h.equalsIgnoreCase("true")) {
                            Intent myIntent = new Intent(getBaseContext(),
                                    ContactList.class);
                            myIntent.putExtra("mobileNumber", username
                                    .getText().toString());
                            startActivity(myIntent);
                        } else {
                            Toast.makeText(getBaseContext(), "Not register or invalid password",Toast.LENGTH_LONG).show();
                            txt.setText("Invalid Credential");
                        }
                    } else {
                        txt.setText("Error while connecting server");
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                    txt.setText("Check internet connection" + e.getMessage());

What is the error in my code.

Thanks in advance

Solution

This may be related to the fact that in API 11 and above accessing the net in Main thread is not allowed you may have to use AsyncTask.

Embed your code block in an AsyncTask, that should solve it.
