I'm trying to refresh my three tabs when I get back from a "Search activity". I was searching about destroy them and recreates them in onPause but doesn't work. "Search activity" is an activity atached in an action bar on my Main Activity. When I call this method in my "Search Activity" I want to refresh all the tabs
public void closeSearchActivity() {
SharedPreferences.Editor editor = preferencias.edit();
editor.putString("actual", xmlActual.toString());
editor.putString("forecast", xmlForecast.toString());
editor.commit();
finish();
}
My main activity
