Android how to add ic_lancher on action bar

I am using android navigation Drawer. created by eclipse. I want to add my ic_launcher on the action bar. as it would normally show.

I also set the min API to 14.

styles //-------------------------------------------------------------------------------------------

<!-- the theme applied to the application or activity -->
<style name="CustomActionBarTheme"
       parent="@style/Theme.AppCompat.Light.DarkActionBar">
    <item name="android:actionBarStyle">@style/MyActionBar</item>

    <!-- Support library compatibility -->
    <item name="actionBarStyle">@style/MyActionBar</item>
</style>

<!-- ActionBar styles -->
<style name="MyActionBar"
       parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
    <item name="android:background">@color/orange_dark</item>

    <!-- Support library compatibility -->
    <item name="background">@color/orange_dark</item>
</style>

here is my manifest
