Question

I am using soap base web service.. I used this example n I am able to do parsing and get response but when I try for different one by making some change in that. I am getting below mentioned errors in my project my code is below pls take a look..

public class MainActivity extends ActionBarActivity implements OnClickListener {

    TextView tv1;
    EditText edname, edemail, edpassword;
    Button btnSubmit;
    private final String NAMESPACE = "http://tempuri.org/";
    private final String URL = "http://208.109.86.236:8080/API.asmx";
    private final String SOAP_ACTION = "http://tempuri.org/PlayerSignup";
    private final String METHOD_NAME = "PlayerSignup";
    private String TAG = "PGGURU";
    private static String stusername;
    private static String stpassword;
    private static String stemail;
    private static String responsea;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv1 = (TextView) findViewById(R.id.tv1);
        edname = (EditText) findViewById(R.id.editText1);
        edpassword = (EditText) findViewById(R.id.editText2);
        edemail = (EditText) findViewById(R.id.editText3);
        btnSubmit = (Button) findViewById(R.id.button1);
        btnSubmit.setOnClickListener(this);
        // throw new RuntimeException();
    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        if (edname.getText().toString() != ""
                && edpassword.getText().toString() != ""
                && edemail.getText().toString() != "") {
            stusername = edname.getText().toString();
            stpassword = edpassword.getText().toString();
            stemail = edemail.getText().toString();
            Log.i("username", stusername);
            Log.i("password", stpassword);
            Log.i("email", stemail);
            AsyncCallWS task = new AsyncCallWS();
            // Call execute
            task.execute();
        } else {
            tv1.setText("Please enter Celcius");
        }
    }

    private class AsyncCallWS extends AsyncTask<String, Void, Void> {
        @Override
        protected Void doInBackground(String... params) {
            Log.i(TAG, "doInBackground");
            getFahrenheit(stusername, stpassword, stemail);
            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
            Log.i(TAG, "onPostExecute");
            tv1.setText(responsea);
        }

        @Override
        protected void onPreExecute() {
            Log.i(TAG, "onPreExecute");
            tv1.setText("Calculating...");
        }

        @Override
        protected void onProgressUpdate(Void... values) {
            Log.i(TAG, "onProgressUpdate");
        }

    }

    public void getFahrenheit(String name, String password, String email) {
        // Create request

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        // Property which holds input parameters
        PropertyInfo celsiusPI = new PropertyInfo();
        // Set Name
        celsiusPI.setName("Username");
        // Set Value
        celsiusPI.setValue(stusername);

        celsiusPI.setName("Password");
        // Set Value
        celsiusPI.setValue(stpassword);

        celsiusPI.setName("Email");
        // Set Value
        celsiusPI.setValue(stemail);

        // Set dataType
        celsiusPI.setType(String.class);
        // Add the property to request object
        request.addProperty(celsiusPI);
        // Create envelope
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        envelope.dotNet = true;

        // Set output SOAP object
        envelope.setOutputSoapObject(request);

        // Create HTTP call object
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

        try {
            // Invole web service
            Log.i("aaaa", "aaaaaaaaaaa");
            androidHttpTransport.call(SOAP_ACTION, envelope);
            Log.i("bbbb", "bbbbbbbbbbbbbbb");
            // Get the response
            SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
            // SoapObject response = (SoapObject) envelope.getResponse();
            // Object result= (Object)envelope.getResponse();
            Log.i("cccc", "ccccccccccccc");
            // Assign it to fahren static variable
            responsea = response.toString();
            Log.i("dddd", "dddddddddddd");

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

}

I am getting exception on this line

SoapPrimitive response = (SoapPrimitive) envelope.getResponse();

Answer 1

I just navigated to http://208.109.86.236:8080/API.asmx?op=PlayerSignup and executed a test request. I got this response:

{"LoginStatus":true,"Message":"Successfully Registered","AccessToken":"dfUW4Xq8u1w="}

This is JSON. The SOAP protocol operates on XML. You need to change your server to return data in the appropriate XML schema.
