Need advice in how to update my Activity due to contact info changes
<p>I have an activity which queries and display some Contact Information. 
And it has a button which launches the intent for 'Edit Contact' (the default Android activity). What should I do to refresh my view in case user edits Contact Information?</p>

<ul>
<li>requery in the onResume() of my activity?</li>
<li>add a content observer?</li>
</ul>

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