Question

My question is: how can I determine if my widget is already placed on the home screen? For example: I added the widget for the first time, and when I try to add it again, in onUpdate() method, I want to execute come code. Something like

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
        int[] appWidgetIds) {

if(widget_already_exists){

 //do something

   }
}

Is there any way to do that?

Thanks. Alex Ady*

Keep track of your app widget IDs. When you see a new one in onUpdate() and you already had one, then the user is adding a second instance. Don’t forget to remove them from your log in onDeleted() of your AppWidgetProvider.
