Actually the Widget uses a RemoteView and you service that view in an AppWidgetProvider which must register one or more BroadcastReceivers to handle calls from the AppWidgetManager for updated views or your own events (through Intents).
The Activity is only used for the optional configuration code that is run when the user installs the widget in the home screen but after that Activity finishes the system's AppWidgetManager activates your BroadcastReceivers. You can do things like register a click listener for the RemoteView that will invoke either the same config Activity or another Activity that provides perhaps extended functionality for the App. If you want to do something like update the Widget at regular intervals you must implement your own timer using the AlarmManager with a PendingIntent and a BroadcastReceiver to handle the event when the alarm is triggered. Best to keep your own record of the RemoteView to be updated for each appWidgetId so that your private internal BroadcastReceivers can update it. You can use the AppWidgetManager.updateAppWidget() at any time not just when you get the ACTION_UPDATE intent.
