Question

我的班级ClassMultiPoint包含子类。

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oPoints中获取对象GSON的值：

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

我尝试使用oPoints.message。

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

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

我尝试保持方法和属性的名称不变，但proguard重命名为：

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（静态）类的方法和属性名称的正确方法是什么？

Answer 1

如果您不希望对您的班级成员进行模糊处理，请使用Gson提供的SerializedName注释。例如：

public class ClassMultiPoints
{
   @SerializedName("message")
   public String message;
   @SerializedName("data")
   public List<ClassPoints> data;

   ...

}

此外，请确保您也为Gson库添加了正确的proguard配置。例如：

##---------------Begin: proguard configuration for Gson ----------
# Gson uses generic type information stored in a class file when working with
#fields. Proguard removes such information by default, so configure it to keep
#all of it.
-keepattributes Signature

# For using GSON @Expose annotation
-keepattributes *Annotation*

# Gson specific classes
-keep class sun.misc.Unsafe { *; }
#-keep class com.google.gson.stream.** { *; }

# Application classes that will be serialized/deserialized over Gson
-keep class com.google.gson.examples.android.model.** { *; }

##---------------End: proguard configuration for Gson ----------

谢谢Waqas！

我为我的案子找到了解决方案：

-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 ----------

另外我不在我的班级中使用@SerializedName("message")，在没有序列化的情况下，配置工作正常。

Answer 3

我还发现在使用Dexguard的优化选项时我需要-keepclassmembers。如果没有这个，我的几个模型对象就无法反序列化

##---------------Begin: proguard configuration for Gson  ----------
# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default, so configure it to keep all of it.
-keepattributes Signature

# For using GSON @Expose annotation
-keepattributes *Annotation*

# Application classes that will be serialized/deserialized over Gson, keepclassmembers
-keep class com.myapp.model.** { *; }
-keepclassmembers class com.myapp.model.** { *; }

Answer 4

如果你像我一样使用@Expose注释，你可以告诉ProGuard保留任何用它注释的字段：

# keep anything annotated with @Expose
-keepclassmembers public class * {
    @com.google.gson.annotations.Expose *;
}
# Also keep classes that @Expose everything
-keep @com.google.gson.annotations.Expose public class *

Answer 5

要从混淆中排除您的类，请保留InnerClasses的属性，保留您的类并保留类的类成员，例如。

-keepattributes InnerClasses
 -keep class com.yourproject.YourClass**
 -keepclassmembers class com.yourproject.YourClass** {
    *;
 }

Answer 6

您使用了内置的@Keep注释，请参阅此link

Answer 7

您可以跳过所有请求类型类别中的混淆处理

open class Request
data class Example(val name: String) : Request()

proguard-rules.pro

-keepclassmembers class * extends <your-package-name>.util.ws.Request { *; }

Answer 8

Proguard 6.1无法处理库中具有泛型的接口。在此处查看错误报告： https://sourceforge.net/p/proguard/bugs/765/

Answer 9

该主题已经有了令人惊叹的答案，但是请不要忘记添加

-keep public class * extends java.lang.Exception

否则，当您在Firebase上看到它们时，所有崩溃都将被混淆。
