The restoration is based on the mapping file +that ProGuard can write out during obfuscation. The mapping file links the +original class names and class member names to their obfuscated names. +<p> + +<hr> +<address> +Copyright © 2002-2009 +<a href="http://www.graphics.cornell.edu/~eric/">Eric Lafortune</a>. +</address> +</body> +</html> + |
