Android styles.xml windowNoTitle (ActionBarActivity) -

i want hide title bar (where activity tile shown) in application. i'm doing setting android:windownotitle item true. works fine devices api level 19. tested device running api level 10 , hides notification bar. tile bar still shown.

here res/values/styles.xml

<resources>     <style name="appbasetheme" parent="theme.appcompat.light">         <item name="android:windownotitle">true</item>         <item name="android:windowfullscreen">true</item>     </style>  </resources> 

edit: i'm using appbasetheme theme in manifest. there no other styles.xml files in other value-vxx folder.

edit#2: i'm extending actionbaractivity activity.

i use 1 theme devices , works on api level 8 16 (since have 5 physical devices). i'm sure it's working on 17-19 devices too.

make sure in manifest file (in application section), there line android:theme="@style/apptheme"

try using theme:

<style     name="appbasetheme"     parent="android:style/theme.notitlebar.fullscreen"     >     <item name="android:windownotitle">true</item>      ...  </style> 

and remove styles/themes in values-xy folders

[edit]

since appcompat theme not full screen, definition, statusbar go away, not titlebar

if don't need actionbar offered appcompat, should rid of appcompat possible: don't bloat apps unneeded , unwanted things

for instance, have header bar , footer bar, these relativelayouts implemented own.
, still have freedom of using whole screen surface.
