you can consume restful services very easily. and for data exchange prefer json rather than XML. i am attaching one sample of restful service call from android client with JSON.

  public class LoginService {

 loginurl="http:/yourhostname.com/Service.svc/Service/ValidateMobileUser";
/**
 * This method is used to validate client name from wcf
 * 
 * @param 1: username
 * @param 2: password    * 
 * @return true or false as string value
 */
public String authenticate(String userName, String passWord
        ) throws JSONException, IllegalStateException,
        IOException,NullPointerException {
    Log.d("input authenticate method", userName + passWord );
    HttpPost request = new HttpPost(loginurl);
    request.setHeader("Accept", "application/json");
    request.setHeader("Content-type", "application/json");
    JSONObject json = new JSONObject();
    json.put("UserName", userName);
    json.put("Password", passWord);     
    json.toString();
    JSONStringer str = new JSONStringer().object().key("clientEntity")
            .value(json).endObject();
    StringEntity entity = new StringEntity(str.toString());
    request.setEntity(entity);
    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpResponse response = httpClient.execute(request);
    Log.e("Status code ", "status code is " + response.getStatusLine());
    HttpEntity responseEntity = response.getEntity();
    char[] buffer = new char[(int) responseEntity.getContentLength()];
    InputStream stream = responseEntity.getContent();
    InputStreamReader reader = new InputStreamReader(stream);
    reader.read(buffer);
    stream.close();
    String response_str = new String(buffer);
    int i = response.getStatusLine().getStatusCode();
    if (i == 200) {
        Log.d("output authenticate method", response_str);

        return response_str;
    } else {
        response_str = Integer.toString(i);

        return response_str; 
    }
    }

    }

I have used restful WCF and used Json in my code. you can use this as template for restful services with json. for restful services.

i would prefer restful with json but if you want to read about ksoap tutorials i suggest you to read: http://www.devx.com/wireless/Article/39810/1954 How to call a WCF service using ksoap2 on android?
