Since Jellybean (4.1) there is a new method that doesn't rely on the WindowManager. Instead use setSystemUiVisibility off of the Window, this gives you more granular control over the system bars than using WindowManager flags. Here is a full example:

if (Build.VERSION.SDK_INT < 16) { //ye olde method
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
} else { // Jellybean and up, new hotness
    View decorView = getWindow().getDecorView();
    // Hide the status bar.
    int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
    decorView.setSystemUiVisibility(uiOptions);
    // Remember that you should never show the action bar if the
    // status bar is hidden, so hide that too if necessary.
    ActionBar actionBar = getActionBar();
    if(actionBar != null) {
         actionBar.hide();
    }
}
