    Most likely, you are calling requestWindowFeature() after calling setContentView(). It may be you are not doing that directly, but that classes you inherit from are, because you are doing some other things slightly out of sequence.

    So, find out where you are doing that and change the order such that you call requestWindowFeature() first.

    For example, here is a sample project from one of my books that uses the progress-indicator-in-the-title-bar trick and therefore needs to call requestWindowFeature(). I had to do that in onCreate() before calling setContentView() on the activity.
