I have an app that uses the AppCompat support libary for ActionBars. Now I tried to create a new themes.xml file with some style for that purpose.<         
        
Add the below in styles.xml under res/values-14
<style name="Theme.Styled" parent="@style/Theme.AppCompat.Light">
    <!-- Setting values in the android namespace affects API levels 14+ -->
    <item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>
</style>
<style name="Widget.Styled.ActionBar" parent="@style/Widget.AppCompat.Light.ActionBar">
    <!-- Setting values in the android namespace affects API levels 14+ -->
    <item name="android:background">#FFFFFF</item>
</style>
You would then need add the following into the values folder: res/values/styles.xml
<style name="Theme.Styled" parent="@style/Theme.AppCompat.Light">
    <!-- Setting values in the default namespace affects API levels 7-13 -->
    <item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>
</style>
<style name="Widget.Styled.ActionBar" parent="@style/Widget.AppCompat.Light.ActionBar">
    <!-- Setting values in the default namespace affects API levels 7-13 -->
    <item name="background">#FFFFFF</item>
</style>

Notice the change for API level 14+
 <item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>
To API level 7-13
 <item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>
