[android-developers] How to launch browser from wallpaper?

I'm trying to launch the browser from a wallpaper, but I get a
NullpointerException...
code looks like this:

Intent i = new Intent();

i.setAction(Intent.ACTION_VIEW);
i.addCategory(Intent.CATEGORY_BROWSABLE);
i.setData(Uri.parse("http://google.com"));

Activity activity = new Activity();
activity.startActivity(i);
