Hi all, I'm developing what amounts to an RSS homescreen widget that periodically (every few hours) downloads headlines from an RSS feed, then displays each headline in the widget one at a time, cycling to a new item every 10 seconds.
All this functionality is working correctly, however watching some log statements generated by the widget on the DDMS console, I see that even when the homescreen of the device is not displayed (either another application is in the foreground, or the display itself is asleep), the widget content is still cycling every 10 seconds. This is obviously a concern for battery life. Currently I'm using an AlarmManager to handle the cycling of the widget content at this 10 second interval, but I have no idea how to suspend the alarm when the homescreen is not displayed or the device is asleep. I have scoured the documentation, but cannot find any obvious event I can listen for or API I can query to find out if the homescreen is currently displayed or not. Google's "News and Weather" widget that comes out of the box with Froyo has similar functionality to the widget I'm developing, but it does seem to stop cycling through news items when the homescreen is not in the foreground or the screen is off. Any help on how to achieve this would be greatly appreciated! Regards, Luke. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
