防止 ProGuard 混淆类成员名称 [英] Prevent class member name obfuscation by ProGuard

问题描述

我的类 ClassMultiPoint 带有子类.

public class ClassMultiPoints
 {
   public String message;
   public List<ClassPoints> data;

   public class ClassPoints
    {
      public String id;
      public List<ClassPoint> points;
      public class ClassPoint
       {
         public String speed;
         public String bearing;
       }
    }
 }

我将从解析 GSON 中获取对象 oPoints 的值:

I will get value of object oPoints from parse GSON:

oPoints = gson.fromJson(jsonString, ClassMultiPoints.class);

我尝试使用 oPoints.message.

当我在没有 proguard 的情况下运行我的应用程序时，应用程序运行成功.当我使用 proguard 运行我的应用程序时，我的应用程序崩溃了.

When I run my application without proguard app run success. When I run my app with proguard my app crash.

我认为问题是:proguard 将我班级的属性 'oPoints.message' 重命名为短 'a'.

I think problem is: proguard rename attribute 'oPoints.message' of my class to short 'a'.

我尽量保持方法和属性的名称不变，但 proguard 重命名它:

I try keep the names of the methods and attributes is constant, but proguard rename its:

proguard.cfg:

-injars      bin/classes
-injars      libs
-outjars     bin/classes-processed.jar
-dontpreverify
-repackageclasses ''
-allowaccessmodification
-optimizations !code/simplification/arithmetic
-keepattributes *Annotation*
-dontskipnonpubliclibraryclasses
-optimizationpasses 5
-printmapping map.txt
-flattenpackagehierarchy

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.MapActivity
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider

-libraryjars  libs/commons-io-2.2.jar
-libraryjars  libs/ftp4j-1.7.1.jar
-libraryjars  libs/gson-2.2.2.jar

-keep public class org.apache.commons.io.**
-keep public class it.sauronsoftware.ftp4j.**
-keep public class com.google.gson.**

-keep public class com.mypackagename.ActivityMonitor$*

-keep public class * extends android.view.View {
    public <init>(android.content.Context);
    public <init>(android.content.Context, android.util.AttributeSet);
    public <init>(android.content.Context, android.util.AttributeSet, int);
    public void set*(...);
}

-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.content.Context {
   public void *(android.view.View);
   public void *(android.view.MenuItem);
}

-keepclassmembers class * implements android.os.Parcelable {
    static android.os.Parcelable$Creator CREATOR;
}

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

保留我的一个(静态)类的方法和属性名称的正确方法是什么?

What is right way to keep names of the methods and attributes of the my one (static) class?

推荐答案

感谢 Waqas！

我找到了适合我的案例的解决方案:

I find solution for my case:

-optimizationpasses 5
-dump class_files.txt
-printseeds seeds.txt
-printusage unused.txt
-printmapping mapping.txt
-optimizations !code/simplification/arithmetic,!field/*,!class/merging*/
-allowaccessmodification
-repackageclasses ''

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.MapActivity
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider

-libraryjars  libs/commons-io-2.2.jar
-libraryjars  libs/gson-2.2.2.jar
-keep public class org.apache.commons.io.**
-keep public class com.google.gson.**
-keep public class com.google.gson.** {public private protected *;}

##---------------Begin: proguard configuration for Gson ----------
-keepattributes *Annotation*,Signature
-keep class com.mypackage.ActivityMonitor.ClassMultiPoints.** { *; }
-keep public class com.mypackage.ActivityMonitor$ClassMultiPoints     { public protected *; }
-keep public class com.mypackage.ActivityMonitor$ClassMultiPoints$ClassPoints { public protected *; }
-keep public class com.mypackage.ActivityMonitor$ClassMultiPoints$ClassPoints$ClassPoint { public protected *; }
# To support Enum type of class members
-keepclassmembers enum * { *; } 
##---------------End: proguard configuration for Gson ----------

此外，我没有在我的班级中使用 @SerializedName("message")，上面的配置在没有序列化的情况下也能正常工作.

Also I don't use @SerializedName("message") in my class, aboved config work fine without serialization.
