what is Flags used for? <p>Would someone explain me the role of flags in functions like setFlags? What exactly does this word mean in that situation...?</p> <p>My example is </p> <pre><code>protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(new RenderView(this)); } </code></pre> <p>I'd like to know what is setFlags used for?</p> <p>I've read the API documentation, but I haven't understood that.</p>
