Simple and easy : dont' do it, forget about it, it doesn't work and it doesn't offer any protection.
Even if your application is unreadable, it won't prevent anyone from copying it and use it, even if you rewrite it in C. Nobody cares about your code anyway, as long as they have the application and can use it (how many people do you know who bought their copy of Photoshop with good money?).
If you're looking for the definite solution against piracy, I have bad news for you : there isn't any. So don't try harder to find a good answer to a bad question.
PS: A super search about "hiding code" or "hiding source" will provide you with many similar discussions.
