Let's make a call

Now we know when we're close to our friends, what are we likely to want to do when we're close? Drop in! But we're polite so we'll call them first. Let's change our list item click function to call the friend we've clicked. We can do this by firing a DIAL_ACTION intent.

Intent i = new Intent(); i.setAction(DIAL_ACTION); i.setData(new ContentURI(numbers.get(position))); startActivity(i);

The phone dialer has registered an IntentReceiver filtered onDIAL_ACTION so it will react to this.
