AlarmManager uses a PendingIntent. There are PendingIntent flavors that call startActivity(), startService(), or sendBroadcast() on the underlying Intent. Any of those are valid, but: 1. startActivity() is a really screwy choice for AlarmManager 2. If you are trying to do the work when the device is asleep, using a _WAKEUP alarm, you need to use sendBroadcast(), due to some peculiarities of how AlarmManager works In your case, the work you are trying to do (check the battery level and update the app widget) *happens* to be fairly quick, so you can probably get away with just having the AlarmManager PendingIntent do a sendBroadcast() to your AppWidgetProvider, where you do the work. Most of the examples you see are for things where the work to be done on a scheduled basis takes much more time than this, where the story gets more complicated. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android Training...At Your Office: http://commonsware.com/training -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
