android - 使用 Android proguard 忽略外部库

Question

我想使用 Proguard 主要是出于混淆的原因。

我对 Android 中的 proguard 有疑问。我使用 simpleframework 来解析 XML；它的外部。

在 proguard 配置文件中：

    -keepattributes *Annotation*,EnclosingMethod    
    -keep public class org.simpleframework.**{ *; }
    -keep public class org.simpleframework.xml.**{ *; }
    -keep public class org.simpleframework.xml.core.**{ *; }
    -keep public class org.simpleframework.xml.util.**{ *; }
    -keep public class org.simpleframework.xml.stream.**{ *; }
    -keep public class javax.** { *; }
    -keep public class javax.xml.stream.**{ *; }

    -keep public class org.simpleframework.** {
      public void set*(***);
      public *** get*();
    }

错误：

我不知道如何解决这个问题。gradle cfg 的路径没问题。

在毕业典礼上：

    buildTypes {
        release  {
            runProguard true
            proguardFile file('proguard.txt')
            signingConfig signingConfigs.release
        }
    }

这个 proguard 配置对我有帮助：Proguard 混淆正在破坏 simplexml

感谢 eXistPierre 的帖子，这是我让它工作所需的最低要求：

-libraryjars <java.home>/lib/rt.jar(java/**,javax/**)
-keep public class org.simpleframework.**{ *; }
-keep class org.simpleframework.xml.**{ *; }
-keep class org.simpleframework.xml.core.**{ *; }
-keep class org.simpleframework.xml.util.**{ *; }
-keepattributes *Annotation*
-keepattributes Signature

我还需要添加以下内容，以便可以读写我的类对象：

-keepclassmembers class com.package.app.ClassItem{ *; }

这些不是输出中的错误，而是您可以跳过的警告：

-dontwarn org.simpleframework.xml.stream.**

或在一般情况下：

-dontwarn

PS跳过后我得到了

值不是参考值 [proguard.evaluation.value.InstructionOffsetValue]

通过将下一行添加到 proguard已修复

-optimizations !class/unboxing/enum
