Hallo zusammen,
ich würde gerne die Sprache meiner App ändern wenn der user in seinem Handy (über setting) die Sprache sein Handy ändert.
hab diverse Beispiele im net angeschaut. Aber funktioniert bei mir irgendwie nicht 
Das ist mein Code:
Code: strings.xml
<resources>
<string name="app_name">SaSiOutlet</string>
<string name="title_activity_login">login</string>
<string name="title_activity_register">register</string>
<string name="title_activity_search_item">SearchItem</string>
<string name="title_activity_favorite_item">FavoriteItem</string>
<string name="title_activity_shopping_item">ShoppingItem</string>
<string name="title_activity_my_side">MySide</string>
<string name="title_activity_base">BaseActivity</string>
<string name="shopping">Shopping</string>
<string name="langselection">selection</string>
</resources>Code: strings.xml (indem Ordner values-ira)
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="shopping">خريد</string>
<string name="title_activity_my_side">مشخصات</string>
<string name="langselection">انتخاب</string>
</resources>Code: activity_shopping.xml
<?xml version="1.0" encoding="utf-8"?>

app:menu="@menu/bottom_navigation_menu">

</RelativeLayout>
