WARNING: the following is purely hypothetical and has not been tried by the author. Also, there may be simpler solutions. Tests have shown that following the author's advice causes rats in cancer laboratories. You have been warned! --------------------- In theory, you can watch for ACTION_PACKAGE_REPLACED to find when your app has been upgraded. You'd need to watch for your UID in the EXTRA_UID, and you'd get that UID from PackageManager (or perhaps someplace simpler -- not sure if there's a convenience method for that somewhere...). If you can get that working, then you can try one of two approaches to refreshing the app widget. First, it may be that pushing out a regular update to the RemoteViews will suffice, no different than your regular app widget update process. If that is insufficient, you can probably achieve a similar end by pushing out an update with a totally different layout (e.g., an empty one) and, milliseconds later, pushing out a regular update back to your desired layout. You could use AlarmManager to schedule the second update. As the WARNING suggests, your mileage may vary. Unless you are from outside of the US, in which case your kilometerage may vary. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android App Developer Books: http://commonsware.com/books -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
