Android proguard用法详解

Java的字节码一般是非常容易反编译的。为了很好的保护Java源代码,我们往往会对编译好的class文件进行混淆处理。ProGuard的主要作用就是混淆。当然它还能对字节码进行缩减体积、优化等,但那些对于我们来说都算是次要的功能。 引用ProGuard官方的一段话来介绍就是: 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
