Android - AppWidgetProvider refresh content after configure activity

I've got a configuration activity fired from an appWidget button. If some parameters for the app are changed within the configuration activity, once saved those i should close the current activity (finish()) and refresh the appWidjet textviews content. Any chance I can force the refresh/update? Thanks!

You can update appswidget from any activity on any event in app:

 RemoteViews views = new RemoteViews(getPackageName(), R.layout.appswidget);
 views.setTextViewText(R.id.txtInfo, "Tiwari");
 ComponentName thisWidget = new ComponentName(v.getContext(), WidgetProvider.class);
 AppWidgetManager manager = AppWidgetManager.getInstance(InfoActivity.this);
 manager.updateAppWidget(thisWidget, views);

here RemoteViews view that will updated here, and by manager.updateAppWidget(), onUpdate() of AppWidgetProvider will called and refresh on appWidget.

you will get here a good demo.

I suggest you send a broadcast message to the widget from the configuration activity. The same broadcast message that you will send otherwise to it when you want to refresh its state.

Intent refreshIntent = new Intent(this, WidgetProvider.class);
refreshIntent.setAction(WidgetProvider.ACTION_RELOAD);
refreshIntent.putExtra(WidgetProvider.EXTRA_WIDGET_ID, widgetId); 
sendBroadcast(refreshIntent);

On the WidgetProvider you just process the new message received

    @Override
    public void onReceive(Context context, Intent intent) {
        super.onReceive(context, intent);
            // do your stuff here on ACTION_RELOAD
    }
