How to get Twitter's user's latest tweets in Android
===

I'm developing a small application that, given a user name, it gets the user tweets. It should check for new tweets regularly. The question is how to detect new tweets ?

I use the simple way for getting tweet feed by sending get request on the link 

> http://twitter.com/statuses/user_timeline/userName.json". 

No authentication, no login, no hard stuff (I need your comments also if this method has some disadvatages)

Then, I parse the output JSON object and get the tweets. 

For checking new tweets I'm thinking about comparing the date of the last tweet I get with the tweet feed (e.g. 5 tweets) until i reach some one with a date less than or equals the last one I have.

So my questions in short are :

Is the method I use for getting tweets a good solution or have problems? 
Is there a better way to get the new tweets rather than the one I suggested ?
