Holoeverywhere : how to programmatically remove at runtime the action bar from an activity

Which is the correct way to remove the action bar inside an activity ? My activity extends org.holoeverywhere.app.Activity I've a custom Application class that extends org.holoeverywhere.app.Application and at startup execs this static code : ``` ThemeManager.setDefaultTheme(ThemeManager.DARK); ThemeManager.map(ThemeManager.DARK, R.style.Holo_Demo_Theme); ThemeManager.map(ThemeManager.LIGHT, R.style.Holo_Demo_Theme_Light); ThemeManager.map(ThemeManager.MIXED, R.style.Holo_Demo_Theme_Light_DarkActionBar); ThemeManager.map(ThemeManager.DARK | ThemeManager.FULLSCREEN, R.style.Holo_Demo_Theme_Fullscreen); ThemeManager.map(ThemeManager.LIGHT | ThemeManager.FULLSCREEN, R.style.Holo_Demo_Theme_Light_Fullscreen); ThemeManager.map(ThemeManager.MIXED | ThemeManager.FULLSCREEN, R.style.Holo_Demo_Theme_Light_DarkActionBar_Fullscreen); ``` in my activity : ``` protected void onCreate(Bundle savedInstanceState) { ThemeManager.removeTheme(this); setTheme(ThemeManager.DARK | ThemeManager.FULLSCREEN); super.onCreate(savedInstanceState); setContentView(R.layout.activity_login); ``` if I add `requestWindowFeature(Window.FEATURE_NO_TITLE)` in the code, on an `android 4.1.1` -table- the bar is removed while on an handset `-android 2.3.3`- the bar is not removed. Before introducing holoeverywhere everything worked fine with just `requestWindowFeature(Window.FEATURE_NO_TITLE).` Which is the correct way to remove at runtime the actionbar in holoeverywhere ? (I want to do it at runtime because the user has the option to set a DARK or LIGHT layout, with a DARK default)
