Android SOAP NTLM example?

I've tried to google around for a working example. I've tried KSOAP2 and JCIFS examples but no success. The web service i'm trying to connect is 3rd parties (Microsoft Dynamics NAV) and can't be modified. It uses SOAP and either SPNEGO or NTLM authentication. And I guess it's already NTLMv2 but I'm not sure on that.
Can anybody please suggest me a full code for the following SOAP request?

$<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:item="urn:microsoft-dynamics-schemas/page/items">
 $   <soapenv:Header/>
 $   <soapenv:Body>
 $      <item:ReadMultiple>
 $         <!--1 or more repetitions:-->
 $         <item:filter>
 $            <item:Field>No</item:Field>
 $            <item:Criteria>1000</item:Criteria>
 $         </item:filter>
 $         <item:setSize>500</item:setSize>
 $      </item:ReadMultiple>
 $   </soapenv:Body>
 $</soapenv:Envelope>
 

I've validated this request with soapUI and it works fine. But when I tried to run it with KSOAP2 and JCIFS I get an error message "Connection refused".
Important to note I am a beginner in Java and Android.
