<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android"> 
  <item android:id="@+id/addFriendMenu"
     android:text="Add Friend"
     android:showAsAction="ifRoom"/> 
</menu>

• android:icon: This is an image resource to display for the menu item. We used a built-in Android one for a generic plus icon.
