ReTrace ProGuard Protected StackTrace Online (details)

ProGuard is a free Java class file shrinker, optimizer, obfuscator, and preverifier. It detects and removes unused classes, fields, methods, and attributes. It optimizes bytecode and removes unused instructions. It renames the remaining classes, fields, and methods using short meaningless names. The resulting applications and libraries are smaller, faster, and a bit better hardened against reverse engineering

Typical applications:

  • Reducing the size of Android apps for faster downloads from Google Play, shorter startup times, and smaller memory footprints.
  • Optimizing code for better performance on mobile devices.
  • Protecting applications and libraries against reverse-engineering and tampering.
