<!--
    As we're using ActionBarCompat, any action item attributes come from ActionBarCompat's XML
    namespace instead of the android namespace. Here we've added a new support namespace added to
    the menu element allowing us to use the 'showAsAction' attribute in a backwards compatible way.
    Any other action item attributes used should be referenced from this namespace too
    (actionProviderClass, actionViewClass, actionLayout).
-->
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:support="http://schemas.android.com/apk/res-auto" >

    <!--
        Here we create an item, setting support:showAsAction to display the item as an action if
        there's room on the compatible Action Bar.
    -->
    <item
        android:id="@+id/menu_refresh"
        android:icon="@drawable/ic_action_refresh"
        android:title="@string/menu_refresh"
        support:showAsAction="ifRoom"/>

    <!-- Location item is added in onCreateOptionsMenu() -->

    <!--
        Here we set the settings item to always be in the overflow menu, by setting
        support:showAsAction to never, so it is never displayed as an action item on the compatible
        Action Bar.
    -->
    <item
        android:id="@+id/menu_settings"
        android:icon="@drawable/ic_action_settings"
        android:title="@string/menu_settings"
        support:showAsAction="never"/>

</menu>
