i trying load changed language using easysharedpreferences, im having problem of how load result of saved string, here code: 

public void shqiponclick(view v){     intent startmainactivity = new intent(this, mainactivity.class);     startactivity(startmainactivity);     languagetoload  = "sq"; // language     locale locale = new locale(languagetoload);     locale.setdefault(locale);     configuration config = new configuration();     config.locale = locale;     getbasecontext().getresources().updateconfiguration(config,             getbasecontext().getresources().getdisplaymetrics());     sharedpreferencedata.putstring("lang",languagetoload);  }  public void englishonclick(view v){     intent startmainactivity = new intent(this, mainactivity.class);     startactivity(startmainactivity);     languagetoload  = "en"; // language     locale locale = new locale(languagetoload);     locale.setdefault(locale);     configuration config = new configuration();     config.locale = locale;     getbasecontext().getresources().updateconfiguration(config,             getbasecontext().getresources().getdisplaymetrics());     sharedpreferencedata.putstring("lang",languagetoload);  }

call sharedpreferences() way:

sharedpreferences saherdpreferences =  getpreferencemanager().getsharedpreferences(); sharedpreferences.editor editor = saherdpreferences.edit(); editor.putstring("string", key); editor.apply();

to retreive sharedpreferences() :

 sharedpreferences saherdpreferences = getpreferencemanager().getsharedpreferences();  string str = saherdpreferences .getstring("string", key);
