This is not a answer, but a comment rather, I don't have the 50 rep required to comment.
It all depends on the sort of functionality you want to achieve. I.e. do you want to be able to push new content to the device using the internet such as push notifications.
OR
Do you want the app to make a http connection to a api or your own news service on startup or on button press for example?
UPDATE
Ok you have decided you want something similar to option 2. I am not going to write code for you but I will point you in the right direction and if you get stuck, post a question.
Please take a look at:-

If you have decided this is what you want or similar, this application uses an API calling infrastructure.
The API they use is called FAROO.
http://www.faroo.com/hp/api/api.html
I suggest reading the documentation, deciding if this is indeed what you want, then sign up and get a API key. Afterall it is free! enjoy coding, enjoy the errors that you will receive and persevere =).
How to make a API call
I suggest when using a API, test the queries through the browser first of all or use something like Runscope for testing their services. So first get their URL which is:-
http://www.faroo.com/api
If we were to go to this url we will get a 401 response code, which means unauthorised. This is because we haven't added our unique API key to the html query. So this url can take parameters. We simply append a ? to the end of the url and supply the parameters that FAROO offers such as:-
q which stands for query (what do you want FAROO to search for?)
start which is the number it should start from
length which is the number of results you want FAROO to return
key which is your unique to make the requests
etc etc...
So an example of a complete url would be:-
http://www.faroo.com/api?q=iphone&start=1&length=10&l=en&src=news&f=json
This url is for demonstration purposes... your own url will have a key=YourAPIKey
Also notice how the parameters are separated by & symbols i.e. q=iphone&start=1 so this part q we know stands for query which is iphone & start=1 & so on.
Hope this helps.
