Answer 1

To translate an app you must go to the Translations Editor which is accessible when you open strings.xml. You will have to translate every string yourself and put the desired translation into the Translations Editor. To access different translations the user will have to have their Locale on their device set to one of the country codes that you provide support for. For example in your app you would end up having strings.xml and strings.xml (us) and the app would use Strings from strings.xml as default unless their locale was set to us in which case they would use the strings.xml (us) strings

/***You need to create separate String file for both arabic and English***/

English
 Values
  String.xml
Arabic   
 Values-ar
  String.xml

/**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();
}
