Suggestions about forum app

I would like to create a simple application for my web forum. Like tapatalk but of course simpler. I want some suggestions about the implementation. I think the easy way is just parsing the html code. This way you don't have much flexibility. A better solution is to create a web service and a client for android. I have experience with jax ws web service and connection with android with ksoap. Any suggestions or ideas will be helpful.

Thanks in advance!
