Question

I use DexGuard for obfuscation. I have the stack trace from crash log and the mapping file. When I run retrace.bat, giving it the stack trace and the mapping file, the output is still in the obfuscated format.

Was it helpful?

Solution

Are you using ProGuard's retrace.bat? It cannot deobfuscate stack traces that were obfuscated with DexGuard. Solution is to use DexGuard's retrace tool instead:

java -jar /var/DexGuard/lib/retrace.jar -verbose mapping.txt trace.txt

DexGuard's is backwards compatible, i.e., it can also retrace ProGuard obfuscated stack traces.

OTHER TIPS

This can also happen if DexGuard has obfuscated using non-ASCII characters, and these characters get mangled when you export the log from the device. One (crude) way of working around this is to use adb logcat -B to export the log in binary.
