obsfucators

[lucazd]

Hi, I like to use an obsfucator (free), which do you recommend?

First think hard about if you really need to bother with one.  Chances are you aren't accomplishing everything you expect by using one.

If you are still convinced it is a good idea, I think Proguard is a decent choice.
