    <p>My guess: the Retro Clock widget responds to touches, and fires off the intent that launches the alarm clock setting page. You could look in the Android source code to figure out what intent that would be. To see how to wire up your widget to actually fire the intent, you can look at the <a href="http://developer.android.com/guide/topics/appwidgets/index.html#AppWidgetProvider" rel="nofollow noreferrer">code example in the Android dev guide</a>.</p> <hr/> <p>For a clock widget, it seems like you have two requirements. It needs to update at least once per minute, but it doesn't need to update while the device is asleep. Here's a quote I found:</p> <blockquote> <p>Note: If the device is asleep when it is time for an update (as defined by updatePeriodMillis), then the device will wake up in order to perform the update. If you don't update more than once per hour, this probably won't cause significant problems for the battery life. <strong>If, however, you need to update more frequently and/or you do not need to update while the device is asleep, then you can instead perform updates based on an alarm that will not wake the device.</strong> To do so, set an alarm with an Intent that your AppWidgetProvider receives, using the AlarmManager. Set the alarm type to either ELAPSED_REALTIME or RTC, which will only deliver the alarm when the device is awake. Then set updatePeriodMillis to zero ("0").</p> </blockquote> <p>(from the <a href="http://developer.android.com/guide/topics/appwidgets/index.html#MetaData" rel="nofollow noreferrer">App Widgets guide</a>)</p> <hr/> <p>Incidentally, I got a chance to play with an HTC Hero. I noticed that, when you wake a Hero from sleep, the hands on its analog clock widget start at 12. Then, it spins the hands around to get to the proper time. This is probably because they don't update it while the phone is sleeping.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
