Connect to Exchange using Ksoap2 for android

Question

I am trying to use ksoap2 to connect to an exchange web server to create an email app in android. So far I have very little to go on since Microsoft doesn't give a straight forward explanation of how to use the autodiscover soap methods. So far this is all I have

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        String userpass = username+password;
        NTCredentials cred = new NTCredentials(userpass);

I am using Android API 21 since it still has the NTCredentials methods. My question then is how do I connect to an exchange server. And then is there anything else I need to do to view email or send email. My app already can show the inbox for a imap or pop3 mail client so can I just connect to the exchange server using ksoap then just use the already defined methods for imap and pop3 to do everything else?

Answer 1

As I mentioned in the comments above I have not done this before, but i have used ksoap2 a bit, so i would try something like this:

String NAMESPACE = "http://www.namespace.com/";
String METHOD_NAME = "MethodName";
String SOAP_ACTION = NAMESPACE+METHOD_NAME;
String URL = "https://www.namespace.com/services/Service.asmx";

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
// Set all input params   
request.addProperty("property", "value");   
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
// Enable the below property if consuming .Net service
envelope.dotNet = true;
envelope.setOutputSoapObject(request);

HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try 
{
    List<HeaderProperty> headerList = new ArrayList<HeaderProperty>();
    //I would use this for authentication
    headerList.add(new HeaderProperty("Authorization", "Basic " + Base64.encode((username+":"+password).getBytes())));

    androidHttpTransport.call(SOAP_ACTION, envelope, headerList);
    SoapObject response = (SoapObject)envelope.getResponse();
}
catch(Exception e)
{
}

This is Basic authentication.
