Questions tagged [proguard]

ProGuard is a tool to shrink, optimize, obfuscate, and preverify Java classes. It is included in the Android SDK.

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. Finally, it preverifies the processed code for Java 6 or for Java Micro Edition.

ProGuard is a command-line tool with an optional graphical user interface and with a plugin for Ant. ProGuard is integrated in Google's Android SDK, where it can be enabled for creating releases, from the command-line or in Eclipse. It is also supported in many development environments for Java Micro Edition.

Proguard is developed by Eric Lafortune and officially supported by GuardSquare.
