Just update the RemoteViews widget instead of completely creating a new one?

So, in my onUpdate method in my AppWidgetProvider class, I ended up executing a non-trivial amount of code to completely restore the new RemoteViews object. The reality is that I really only need to set the text in one of the text views in RemoteViews every time I update. Do I need to modify the RemoteViews that a particular widget already uses?

2013 , API. WidgetProvider, :

AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
rv = new RemoteViews(context.getPackageName(), R.layout.widgetlayout); 
rv.setTextViewText(R.id.ofTextViewInWidgetLayoutXML, "Hello World");
appWidgetManager.partiallyUpdateAppWidget(appWidgetIds[i], rv);

, remoteView.setString, remoteView.setTextViewText

You can update deleted views and then call

ComponentName componentName= new ComponentName(context, YourClass.class);
AppWidgetManager.getInstance(context).updateAppWidget(componentName, remoteViews);

on which AFAIK should update the widget
