Why does IDEA mark this Android code as erronous? It compiles

This is fine:

    findViewById(R.id.cat_name).setVisibility(GONE);

This is not:

    findViewById(R.id.cat_name).setVisibility(0x00000008);


What gives? Both are perfectly valid integers! If I wanted type checking, I'd use an enums (or rather - Google should have, but that's another discussion). Who is checking this? IDEA? Lint? Any way I can configure it to ignore these errors?

PS: If you wonder why I'd use inline constants instead of the defined constants: I don't. But using this method causes the same IDE-error:

public static int booleanToVisibleOrGone(boolean visible) {
    return visible ? View.VISIBLE :  View.GONE;

}
