Creating a new entry dynamically using OData - Android

Hi,

I am developing a sample android project to perform CRUD opertaions using OData services. In this I am facing an issue in building an xml using inbuit APIs. Please find below my query.

I am able to successfully create a new entry by using the POST request. But, in this method i am passing the hardcoded entity xml in the POST body of the request. As i feel this is not an optimized way, Are there any APIs associated with creating an entry where I can just pass the new values instead of passing the entire xml structure.

PFB my code:

String createXml = "<entry xmlns=\"http://www.w3.org/2005/Atom\" xmlns:d=\"http://schemas.microsoft.com/ado/2007/08/dataservices\" xmlns:m=\"http://schemas.microsoft.com/ado/2007/08/dataservices/metadata\"><title type=\"text\">CUSTOMER</title><updated>2014-01-23T12:48:00.009+05:30</updated><category term=\"Service.CustomerObj\" scheme=\"http://schemas.microsoft.com/ado/2007/08/dataservices/scheme\"/><content type=\"application/xml\"><m:properties><d:CUSTID>"
    + "3"
    + "</d:CUSTID><d:LASTNAME>"
    + "jeeri"
    + "</d:LASTNAME><d:FIRSTNAME>"
    + "Nvn"
    + "</d:FIRSTNAME><d:ADDRESS>"
    + "xyz"
    + "</d:ADDRESS><d:CITY>"
    + "abc"+ "</d:CITY></m:properties></content></entry>";

BaseRequest request = new BaseRequest();
request.setListener(this);
request.setRequestUrl(url); // Collection URL
request.setRequestMethod(IRequest.REQUEST_METHOD_POST);
Map<String, String> headers = new HashMap<String, String>();
headers.put("content-type", "application/atom+xml");
request.setHeaders(headers);
request.setData(createXml.getBytes()); 
reqManagerObject.makeRequest(request);

I am looking for an API where if I pass the entry object that contains CUSTID, LASTNAME, FIRSTNAME, ADDRESS and CITY it would build the xml automatically.

Thanks in advance,

Naveen
