cast icon not showing in menu

[ssuresh1295]

Hi I have added item in menu and its not displaying on action bar

<menu xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/media_route_menu_item"
        android:icon="@drawable/ic_search_black_24dp"
        app:actionProviderClass="github.ankyl.castscreen.CastScreenMediaRouteActionProvider"
        android:title="Search"
        app:showAsAction="always" />
   <item
        android:id="@+id/edit"
        android:icon="@drawable/ic_search_black_24dp"
        app:actionViewClass="android.widget.SearchView"
        android:title="Search"
        app:showAsAction="always" />
</menu>

The second item is displaying but media_route_menu_item is not displaying because of app:actionProviderClass="github.ankyl.castscreen.CastScreenMediaRouteActionProvider"
