Android : Opening A Url In The Phone's Default Browser

I'm trying to make test-program that opens a website by pushing a button. I have made a listener and everything, my problem is just that, the url-opening-script makes an error and tells me "Uri cannot be resolved".

Here's the script I use to open up an webpage:

CODE:..........................

I have the import android.app.Activity;, import android.content.Intent; and import android.content.ContentUris; (maybe the last one isn't needed) so I can't find out what's wrong...

I hope someone knows what I've done wrong, or forgot to import...

I've used this pages to get to where I am:
