Using shared preferences you can store the lanuage and get the stored value on screen orientation change.

public String setLocale(String lang) {
    Locale myLocale = new Locale(lang);
    Resources res = getResources();
    DisplayMetrics dm = res.getDisplayMetrics();
    Configuration conf = res.getConfiguration();
    conf.locale = myLocale;
    res.updateConfiguration(conf, dm);
    Intent refresh = new Intent(this, Login.class);
    startActivity(refresh);
    finish();
    // save shared preference here or later, your choice.
    return lang;
}

Code to create and save shared preference.

SharedPreferences  preferences = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor nameEditor = preferences.edit();
nameEditor.putString("saved_lang", lang);
nameEditor.commit();

Code to retrieve value of shared preference.

//To get language when screen changes.
String lang = preferences.getString("saved_lang", "");

You can use the same principal to save other values and settings.
