You'll never ever have to publish the sources of the game you made!

(As I understand the LGPL:) The only thing you have to make public are the modifcations
you make to AndEngine itself. Such stuff usually starts if you check out the AndEngine sourcecode, change something, and build the andengine.jar yourself. While you have to check in such changes, you should do so for your own profit, as otherwise you'd have to merge those changes with it every single other revision made to the AndEngine. As long as you simply drop the andengine.jar into your project, you don't even have to think about it - at all.
Hope this helped clarify things
