How can I observe for any changes to a contact
<p>In android, how can I observe for any changes made to a contact?
I know I need to register for a content observer? But what should be the URI for passing to the registerContentObserver function?</p>

<p>Here is what I tried:</p>

<pre><code>registerContentObserver( ContentUris.withAppendedId(People.CONTENT_URI, personId), true, myContactsObserver);
</code></pre>

<p>But I don't get notified when I change the phone number of the contact.</p>

<p>Thank you for any pointers.</p>
