Android: Ntlm Authentication, Ksoap, And Persistent Connections

After working with iOS and dealing with auth challenges without much of a learning curve, I've found that Windows Authentication is much more complicated of a process in Java/Andro

Solution 1:

I was also struggling about windows authentication from Android. I found android-ntlm-master on https://github.com/masconsult/android-ntlm. Add this class as library in your project.

Change is in NtlmTransport.java class.I made change in call method of NtlmTransport class =>

public List call(String soapAction, SoapEnvelope envelope,
                        List headers, File outputFile)throws IOException, XmlPullParserException {

    HttpResponseresp=null;
    try {
        //setupNtlm(urlString, user, password);  DefaultHttpClienthttpclient=newDefaultHttpClient();
         httpclient.getAuthSchemes().register("ntlm", newNTLMSchemeFactory());
         httpclient.getCredentialsProvider().setCredentials(            
                newAuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT),               
                newNTCredentials(user, password, "", "")
         );
         HttpPosthttpget=newHttpPost(urlString);       
         httpget.addHeader("soapaction",  soapAction);        
         httpget.addHeader("Content-Type", "text/xml; charset=utf-8");
         byte[] requestData = null;
         try {
             requestData = createRequestData(envelope);                 
         } catch (IOException iOException) {
         }
         ByteArrayEntitybyteArrayEntity=newByteArrayEntity(requestData);
         httpget.setEntity(byteArrayEntity);                
         resp = httpclient.execute(httpget); 

         if(resp  == null) {
            System.out.println("Response is null");
         }
         HttpEntityrespEntity= resp.getEntity();

         InputStreamis= respEntity.getContent();
         if(is == null) {
            System.out.println("InputStream is null");
         }
         parseResponse(envelope, is);

    } catch (Exception ex) {
        // ex.printStackTrace();
    }

    if (resp != null) {
        return Arrays.asList(resp.getAllHeaders());
    } else {
        returnnull;
    }
}

And below is the code how I make call:

SoapObjectrequest=newSoapObject(NAMESPACE, PRODUCT_DETAILS_METHOD_NAME);
    request.addProperty("ListingID", Integer.parseInt(Product_ID));
    NtlmTransporthttpTransport=newNtlmTransport();
    httpTransport.setCredentials(URL, USERNAME, PASSWORD, "","");
    SoapSerializationEnvelopeenvelope=newSoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true; 
    envelope.implicitTypes = true;
    envelope.setOutputSoapObject(request);              
    httpTransport.call(PRODUCT_DETAILS_SOAP_ACTION, envelope);
    SoapObjectresponse= (SoapObject) envelope.getResponse();

It worked for me.
