How to prevent my class to be decompiled

Question

I don't want my class to be decompiled.

I have gone through some of the articles and found a patent site Zelix KlassMaster

Is there any free tools available in the market which works in the similar way..

Answer 1

As far as I know there are no free tools with the same set of functions.

In my opinion the mix between ProGuard and Stringer Java Obfuscator is the best and also most cheap way to protect Java and Android applications.

N.B. I'm CEO at Licel LLC. Developer of Stringer Java Obfuscator.
