Android Use Namespace As Prefix For Attributes In Library

I am trying to implement the ActionBar through the support library, v7. Because I want to support the app for Android 2.1 (API level 7) and above. I read in http://developer.androi

Solution 1:

Here is an example of a menu:

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:whatever="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@id/wims_ab_done"
        android:icon="@drawable/white_check_mark"
        android:title="@string/save"
        whatever:showAsAction="always"/>
    <item
        android:id="@id/wims_ab_items_remove"
        android:icon="@drawable/wims_remove"        
        android:title="@string/remove"
        whatever:showAsAction="always"/>

</menu>

The whole philosophy is to have http://schemas.android.com/apk/res-auto in the namespace attribute in root menu. It doesn't matter what is the namespace identifier as long as it's valid and is used as such when using showAsAction attributes. Does this answer your question?
