`ActionBar` not showing icons for items. This is my menu xml so far. It just shows the action overflow with stuff in the action overflow.

```
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
    <item android:id="@+id/action_search"
        android:icon="@drawable/ic_action_search"
        android:title="@string/action_search"
        yourapp:showAsAction="always"  />
</menu>

```
