Is there a way to push an update to a widget from another activity?
It seems like in order to use the AppWidgetManager.updateAppWidget
method, it has to be within the widget code itself? Can i push an
update to the widget from the app personally? I tried this and it
didn't do anything
// Push update for this widget to the home screen
ComponentName thisWidget = new ComponentName(this,
WordWidget.class);
AppWidgetManager manager = AppWidgetManager.getInstance
(this);
manager.updateAppWidget(thisWidget, updateViews);
For example, if I have a calendar app that has a calendar widget..how
do i push changes to the widget if I update an event on the calendar?
I have been looking at the calendar and calendar widget code but I
have yet to figure out how to do this.
Thanks.
