Ok I found an issue here, If I add the widget and there is no room on the homescreen my widget does not get added but both onEnable() and onUpdate() get called. Then after I delete my truly last instance, appWidgetHost still thinks there is another one out there. Is there a way to get a callback somehow that the widget could not be added?
