how to call a soap web service on android

Question!

I am having a lot of trouble finding good information on how to call a standard SOAP/WSDL web service with Android. All I've been able to find are either very convoluted documents and references to "kSoap2" and then some bit about parsing it all manually with SAX. OK, that's fine, but it's 2008, so I figured there should be some good library for calling standard web services.

The web service is just basically one created in NetBeans. I would like to have IDE support for generating the plumbing classes. I just need the easiest/most-elegant way to contact a WSDL based web service from an Android-based phone.



Answers

You may perform soap call as post over http with certain headers. I solved this question without additional libraries like ksoap2 Here is live code getting orders from soap service

private static HashMap<String,String> mHeaders = new HashMap<>();

static {
    mHeaders.put("Accept-Encoding","gzip,deflate");
    mHeaders.put("Content-Type", "application/soap+xml");
    mHeaders.put("Host", "35.15.85.55:8080");
    mHeaders.put("Connection", "Keep-Alive");
    mHeaders.put("User-Agent","AndroidApp");
    mHeaders.put("Authorization","Basic Q2xpZW50NTkzMzppMjR3s2U="); // optional
}public final static InputStream receiveCurrentShipments(String stringUrlShipments)
{
    int status=0;
    String xmlstring= "<soap:Envelope xmlns:soap=\"http://www.w3.org/2003/05/soap-envelope\" xmlns:ser=\"http://35.15.85.55:8080/ServiceTransfer\">\n" +
            "   <soap:Header/>\n" +
            "   <soap:Body>\n" +
            "      <ser:GetAllOrdersOfShipment>\n" +
            "         <ser:CodeOfBranch></ser:CodeOfBranch>\n" +
            "      </ser:GetAllOrdersOfShipment>\n" +
            "   </soap:Body>\n" +
            "</soap:Envelope>";
    StringBuffer chaine = new StringBuffer("");

    HttpURLConnection connection = null;
    try {
        URL url = new URL(stringUrlShipments);
        connection = (HttpURLConnection) url.openConnection();
        connection.setRequestProperty("Content-Length", xmlstring.getBytes().length + "");
        connection.setRequestProperty("SOAPAction", "http://35.15.85.55:8080/ServiceTransfer/GetAllOrdersOfShipment");

        for(Map.Entry<String, String> entry : mHeaders.entrySet()) {
            String key = entry.getKey();
            String value = entry.getValue();
            connection.setRequestProperty(key,value);

        }

        connection.setRequestMethod("POST");
        connection.setDoInput(true);

        OutputStream outputStream = connection.getOutputStream();
        outputStream.write(xmlstring.getBytes("UTF-8"));
        outputStream.close();

        connection.connect();
        status = connection.getResponseCode();
    } catch (ProtocolException e) {
        e.printStackTrace();
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {

        Log.i("HTTP Client", "HTTP status code : " + status);
    }

    InputStream inputStream = null;
    try {
        inputStream = connection.getInputStream();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return inputStream;
}


Add Soap Libaray(ksoap2-android-assembly-3.2.0-jar-with-dependencies.jar):

public static String Fn_Confirm_CollectMoney_Approval(

        HashMap < String, String > str1,
        HashMap < String, String > str2,
        HashMap < String, String > str3) {

    String METHOD_NAME = "CollectMoney";
    String NAMESPACE = "http://xxx/yyy/xxx";
    String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";
    String SOAP_ACTION = "";

    try {

        SoapObject RequestParent = new SoapObject(NAMESPACE, METHOD_NAME);

        SoapObject Request1 = new SoapObject(NAMESPACE, "req");

        PropertyInfo pi = new PropertyInfo();

        Set mapSet1 = (Set) str1.entrySet();

        Iterator mapIterator1 = mapSet1.iterator();

        while (mapIterator1.hasNext()) {

            Map.Entry mapEntry = (Map.Entry) mapIterator1.next();

            String keyValue = (String) mapEntry.getKey();

            String value = (String) mapEntry.getValue();

            pi = new PropertyInfo();

            pi.setNamespace("java:com.xxx");

            pi.setName(keyValue);

            pi.setValue(value);

            Request1.addProperty(pi);
        }

        mapSet1 = (Set) str3.entrySet();

        soapEnvelope.setOutputSoapObject(RequestParent);

        HttpTransportSE transport = new HttpTransportSE(URL, 120000);

        transport.debug = true;

        transport.call(SOAP_ACTION, soapEnvelope);

        response = (Object) soapEnvelope.getResponse();

        int cols = ((SoapObject) response).getPropertyCount();

Please download and add SOAP library file with your project File Name : ksoap2-android-assembly-3.4.0-jar-with-dependencies

Clean the application and then start program

Here is the code for SOAP service call

    String SOAP_ACTION = "YOUR_ACTION_NAME";
    String METHOD_NAME = "YOUR_METHOD_NAME";
    String NAMESPACE = "YOUR_NAME_SPACE";
    String URL = "YOUR_URL";
    SoapPrimitive resultString = null;

    try {
        SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
        addPropertyForSOAP(Request);

        SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        soapEnvelope.dotNet = true;
        soapEnvelope.setOutputSoapObject(Request);

        HttpTransportSE transport = new HttpTransportSE(URL);

        transport.call(SOAP_ACTION, soapEnvelope);
        resultString = (SoapPrimitive) soapEnvelope.getResponse();

        Log.i("SOAP Result", "Result Celsius: " + resultString);
    } catch (Exception ex) {
        Log.e("SOAP Result", "Error: " + ex.getMessage());
    }
    if(resultString != null) {
        return resultString.toString();
    }
    else{
        return "error";
    }

The results may be JSONObject or JSONArray Or String
