使用 Proguard 混淆 ActionBarSherlock

Question

我正在尝试使用 proguard 和 ant 混淆我的 android 应用程序（eclipse + proguard 永远无法工作，总是以 error 1 失败）。但是我收到了class file ... unexpectedly contains class ... 警告，并且构建失败。我还尝试使用proguard 中的-ignorewarnings 选项。构建成功，但我得到了一个无法使用的包。

这是蚂蚁的输出：

我该如何解决这个问题？

Answer 1

确保您的 proguard 配置文件具有 ActionbarSherlock 的 recommended exclusions：

-keep class android.support.v4.app.** { *; } 
-keep interface android.support.v4.app.** { *; } 
-keep class com.actionbarsherlock.** { *; } 
-keep interface com.actionbarsherlock.** { *; } 
-keepattributes *Annotation*

也尝试添加

-keepclassmembers class **.R$* {
    public static <fields>;
}

按照here的建议。

Answer 2

参照。 ProGuard 手册 > 疑难解答 > Warning: class file ... unexpectedly contains class ...

您应该在输入类路径中指定正确的基目录：“-injars ....../classes”。
