/**You can change the application language using the following code:**/

 language =  "en"; or  language =  "ar";

@Override
public void recreate()
{
    if (android.os.Build.VERSION.SDK_INT >= 14)
    {
        super.recreate();
    }
    else
    {
        startActivity(getIntent());
        finish();
    }
}

private void updateLanguage(String language)
{
    Locale locale = new Locale(language);
    Locale.setDefault(locale);
    Configuration config = new Configuration();
    config.locale = locale;
    getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());

    SharedPreferences languagepref = getSharedPreferences("language",MODE_PRIVATE);
    SharedPreferences.Editor editor = languagepref.edit();
    editor.putString("languageToLoad",language);
    editor.apply();

    recreate();
}
