Show Toast message at 10 minute interval
<p>I'm trying to show a <code>Toast</code> message to the user at a 10 minute interval. I'm doing this:</p>

<pre><code>triggerAtTime = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse("2011-07-12 14:00:00").getTime();
</code></pre>

<p>... and now I want to display a <code>Toast</code> message when the system time has reached the given time. How can I do this?</p>
