Hey, thanks for the reply. Glad I am not the only one with this problem :-)
So, I too thought of restructuring my code such that I would instead invoke notifyAppWidgetViewDataChanged(). Unfortunately I got the same results - the message was not pushed to the widget promptly. Although, after you wrote this post I thought to try it again. It seems that my update will unreliably push if I add the notifyAppWidgetViewDataChanged() directly before my call to updateAppWidget(), then the list updates properly. At any rate, this fix seems like a "I-hope-this-works" fix rather than a logical fix. And this does not work every time, for example if I execute the same update block from a different BroadcastReceiver, it does not work. I am at a loss. It looks like there have been others with this problem, too... http://code.google.com/p/android/issues/detail?id=8889 Brad On Jul 29, 3:11 pm, Padma <[email protected]> wrote: > Even I am facing a similar issue with lists in appwidgets.
