From what thread are you ultimately calling
AppWidgetManager.updateAppWidget
?
It has to be the UI thread, I think you should check to make sure.

I have no idea what:
HyvesWidgetService.requestUpdate(appWidgetIds);
does, but that would seem to be taking too long.
And code from the IntentService
/**
* Start this service, creating a background processing thread, if
not
* already running. If started with {...@link #ACTION_UPDATE_ALL},
will
* automatically add all widgets to the requested update queue.
*/
@Override
protected void onHandleIntent(Intent intent) {
// If requested, trigger update of all widgets
if (ACTION_UPDATE_ALL.equals(intent.getAction())) {
AppWidgetManager manager =
AppWidgetManager.getInstance(this);
Log.d(TAG, "Requested UPDATE_ALL action");
requestUpdate(manager.getAppWidgetIds(new
ComponentName(this, HyvesWidgetProvider.class)));
}
onUpdate();
}
onUpdate calls an asynchronous api call, and a callback updates tthe
widget.
Wait, whoa, what? You are already in a background thread. Is
onUpdate() forking yet another thread?
