Can ProGuard reconstruct obfuscated stack traces?
Yes. ProGuard comes with a companion tool, ReTrace, that can ‘de-obfuscate’ stack traces produced by obfuscated applications. The reconstruction is based on the mapping file that ProGuard can write out. If line numbers have been obfuscated away, a list of alternative method names is presented for each obfuscated method name that has an ambiguous reverse mapping. Please refer to the ProGuard User Manual for more details.
