title: android:theme="@android:style/Theme.NoTitleBar.Fullscreen" works on Application level but not at the activity level. Any clue?
body: <p>I need to make one of my activities called <code>MyNoStatusBarActivity.java</code> a full-screen activity.</p>
  
  <p>I have added in the Manifest :</p>
  
  <pre><code>&lt;activity
      android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
      android:name=".MyNoStatusBarActivity"
      android:noHistory="true"
      android:label="@string/app_name"
      android:configChanges="touchscreen|keyboard|keyboardHidden|navigation|orientation"&gt;
      ...
  &lt;/activity&gt;
  </code></pre>
  
  <p>And in the <code>onCreate</code> of my activity :</p>
  
  <pre><code>@Override
  public void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
      requestWindowFeature(Window.FEATURE_NO_TITLE);
  
      getWindow().setFlags(
          WindowManager.LayoutParams.FLAG_FULLSCREEN,
          WindowManager.LayoutParams.FLAG_FULLSCREEN);
  }
  </code></pre>
  
  <p>Doing all this just hides the TITLE bar and not the STATUS bar.</p>
  
  <p>Also if I use the manifest theme on the application level instead of my activity, it works but for all activities of my app which is not what I want. I want the no status bar only for one particular activity.</p>
  
  <p>Help will be really appreciated. Thnx!</p>
  
  <p>P.S : I am ok is this behavior is no longer available in Honeycomb/ICS. I need this just for 2.2 and 2.3</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Tried all the suggestions mentioned in other solutions in SO but no success yet. Theme works when applied to the application level but not on the activity level.</p>
  
  <p>I am using HTC WildFire-S, android ver 2.3.5 </p>
