What is the difference between this piece of code:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowActionBar">false</item>
</style>
and this one:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:windowActionBar">false</item>
</style>
