title: Holoeverywhere : how to programmatically remove at runtime the action bar from an activity
body: <p>Which is the correct way to remove the action bar inside an activity ?</p>
  
  <p>My activity extends org.holoeverywhere.app.Activity</p>
  
  <p>I've a custom Application class that extends org.holoeverywhere.app.Application and at startup execs this static code :</p>
  
  <pre><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);
  </code></pre>
  
  <p>in my activity :</p>
  
  <pre><code>protected void onCreate(Bundle savedInstanceState) {
  
      ThemeManager.removeTheme(this);
      setTheme(ThemeManager.DARK | ThemeManager.FULLSCREEN);
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_login);
  </code></pre>
  
  <p>if I add <code>requestWindowFeature(Window.FEATURE_NO_TITLE)</code> in the code, on an <code>android 4.1.1</code> -table- the bar is removed
   while on an handset <code>-android 2.3.3</code>- the bar is not removed.</p>
  
  <p>Before introducing holoeverywhere everything worked fine with just <code>requestWindowFeature(Window.FEATURE_NO_TITLE).</code></p>
  
  <p>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)</p>
