Why doesn't supportRequestWindowFeature() work?

Question

I have a problem and I've been trying to find the mistake for a couple hours but I just can't find it?

My situation: I don't want that my titlebar appears. My device is a HTC and runs android 2.3.3. I tried it with supportRequestWindowFeature() but somehow it doesn't work.

My code is here:

  @Override
  protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_main);
  }     

Also my MainActivity extends ActionBarActivity.

Place supportRequestWindowFeature above super.oncreate:

@Override
protected void onCreate(Bundle savedInstanceState) {
  supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
}
