Besides, this observer monitors data published by a content provider that lives within the same process (if I'm understanding the structure correctly).
So if there are changes, it means they were pushed by the content provider, which in turn means the process was alive. However, I believe it's still wrong, as I see no reason for the widget provider's onEnabled to be called each time the process is recreated (such as by an alarm or the sticky remote views service). Unless, that is, I'm missing something on app widget lifecycle callbacks. 17.05.2012 18:26 пользователь "Mark Murphy" <[email protected]> написал: > The Android Developers site has a Weather List Widget sample app: > > http://developer.android.com/resources/samples/WeatherListWidget/index.html > > One of the classes in it is WeatherWidgetProvider, which is an > AppWidgetProvider.
