[android-developers] Re: Steps to transfer a simple object from server to android using XML
[Message delayed due to technical difficulties..] raqz and I have been discussing this off-list, so just to sync things up a bit... Raqz asked me about JSON -- possibly in response to your suggestion. It's a good suggestion to consider. I tend to suggest XML by default, because it's more standard and flexible, with a broader set of tools. It gives you far broader interoperability. JSON, by contrast, is more limited, with fewer tools -- and a whole lot less to learn. I should recommend it more often to beginners. It's a less useful skill overall - but it's so very easy to learn that isn't really much of a disadvantage. If, as in this case, all you want to do is get some data from point to point, and have to learn other stuff as well, it's far better to eliminate XML from the equation so you can focus on what's essential. It's also quite easy to support both. I've supported services that provided JSON for web client UIs, and XML for various tools using XSLT and other XML technologies, giving the same functionality to both sets of client.

Thought you actually could according to this article I read couple of weeks ago : http://www.ibm.com/developerworks/opensource/library/x-android/index.html#N1029E Says you can use the XmlSerializer object for that ?

You can also use XmlSerializer to serialize a DOM, together with about a page of code to walk the DOM. That's a whole lot more painful than it ought to be, but it's better than writing XML tags yourself, which if you find yourself doing, you're doing something wrong.

Still prefer JSON, but if talking to legacy systems then you have no choice to go the XML route. Luckily I have total control over back end server process so I have gone the former route. However, been informed my next program might have to talk to XML back end (SOAP) and was looking into kSoap, so that should fun.
