Android Question stdactionbar transparent

[Shivito1]

When I use the following theme with stdactionbar I get errors. is what I'm doing not possible?

SetActivityAttribute(Main, android:theme, @style/CustomActTheme)
CreateResource(values, theme.xml,
<resources>
<style name="CustomActTheme" parent="@android:style/Theme.Material">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:backgroundDimEnabled">true</item>
<item name="android:windowFullscreen">true</item>
<item name="android:colorPrimary">#f44336</item> <!-- action bar -->
<item name="android:colorPrimaryDark">#b71c1c</item> <!-- status bar -->
<item name="android:colorAccent">#2DEA6A</item> <!-- Seekbar,, checkboxes,, switches,, etc. -->
<item name="android:textColorPrimary">#00FF00</item> <!-- ? -->
<item name="android:textColorSecondary">#FF00FF</item> <!-- inactive editText line,, scrollbar -->
<item name="android:textColor">#FFFFFF</item> <!-- menu text,, msgbox title -->
<item name="android:textColorLink">#b71c1c</item>

It will not work if you hide the title bar. However there is no reason to use StdActionBar. Use TabStripViewPager instead.
