忽略Android Proguard中的外部库

Question

我希望使用Proguard主要是为了混淆。

我在Android中使用Proguard遇到了问题。我使用simpleframework来解析XML，它是外部的。

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配置文件的路径是正确的。

在Gradle中：

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

感谢 eXistPierre 的帖子，这是我需要的最少配置：

-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才能读写我的类对象：

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

这就是它。我绝望了，因为我找不到任何解决方案，而这正是我需要做的！非常感谢！！！ - techfly

这个Proguard的配置对我很有帮助：Proguard混淆破坏了SimpleXML

# The following line may be different
-libraryjars <java.home>/lib/rt.jar(java/**,javax/**)

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
# (3)Not remove unused code
-dontshrink

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService
# (2)Simple XML
-keep public class org.simpleframework.**{ *; } 
-keep class org.simpleframework.xml.**{ *; } 
-keep class org.simpleframework.xml.core.**{ *; } 
-keep class org.simpleframework.xml.util.**{ *; }
# (1)Annotations and signatures
-keepattributes *Annotation*
-keepattributes Signature

-keepclasseswithmembernames class * {
    native <methods>;
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

输出中的那些不是错误，而是警告信息，您可以使用以下方式跳过它们：

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

或者在一般情况下：

-dontwarn

顺便提一下，跳过后我得到了以下错误信息：

该值不是引用值 [proguard.evaluation.value.InstructionOffsetValue]

通过将下一行代码添加到proguard中，问题得到了解决。

-optimizations !class/unboxing/enum
