Remove ActionBar from transparent windows

Hi,

I would like to completely remove the ActionBar from all the windows, I succeeded doing this by creating a theme like this:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.MyApp" parent="@style/Theme.Titanium">
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowActionBar">false</item>
    </style>
</resources>

Any ideas on how to also remove it from this kind of windows?
