用于 Android Proguard 混淆的 ANT 构建 [英] ANT build for Android Proguard obfuscation

问题描述

任何人都可以分享适用于 Android 的示例/简单混淆 ANT 任务吗?前提是我有完整的 APK，我只需要通过 *class hru Proguard 然后准备 *.dex 来构建 APK

Can anyone share with sample/simple obfuscation ANT task for Android? Provided that I do have complete APK and I need just pass *class hru Proguard and then prepare *.dex to build APK

推荐答案

我找到了解决方案:

1. 获取 Proguard - 将 proguard.jar 复制到已知目录(例如 MyProject/proguard)
2. 准备 proguard.cfg - 描述优化/混淆的内容和方式.Proguard 的手册
中详细描述了此过程
3. 准备遵循 ANT 的 build.xml(或类似的) - 非常感谢 这家伙

1. Get Proguard - copy proguard.jar into known directory (say MyProject/proguard)
2. Prepare proguard.cfg -describing what and how optimize/obfuscate. This process thoroughly described in Proguard's manual
3. Prepare following ANT's build.xml (or smth like this one) - great thanx to this guy

更新完整的build.xml

UPDATE complete build.xml

1. 此 ANT 任务必须在 Java 构建器之后和 Android 包构建器之前添加到 Eclipse 的构建器(属性/构建器)任务中.

1. This ANT task has to be added to Eclipse's builders (Properties/Builders) tasks after Java builder and before Android package builder.

按全部构建"(最好在 Eclipse 菜单中关闭自动构建检查)

Press "Build All" (it's better to off Automatic Build check in Eclipse menu)
