ProGuard에 의한 클래스 멤버 이름 난독 화 방지

ProGuard에 의한 클래스 멤버 이름 난독 화 방지

---

ClassMultiPoint하위 클래스가 있는 클래스가 있습니다.

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;
       }
    }
 }

oPoints구문 분석에서 객체 값을 얻습니다 GSON.

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

나는 사용을 시도합니다 oPoints.message.

proguard앱 실행이 성공 하지 않고 애플리케이션을 실행할 때 . proguard앱 충돌로 앱을 실행할 때 .

문제는 내 클래스의 proguard속성 이름 'oPoints.message'을 short로 변경하는 것 입니다 'a'.

메서드와 속성의 이름을 일정하게 유지하려고하지만 proguard이름을 다음과 같이 변경합니다.

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>;
}

내 하나의 (정적) 클래스의 메서드 이름과 속성을 유지하는 올바른 방법은 무엇입니까?

클래스 멤버를 난독 화하지 않으려면 SerializedNameGson에서 제공 하는 주석 을 사용하십시오 . 예를 들면 :

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

   ...

}

또한 Gson 라이브러리에도 적절한 proguard 구성을 추가해야합니다. 예를 들면 :

##---------------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 ----------

Thanks Waqas!

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 ----------

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

I also found I need to -keepclassmembers when using Dexguard's optimise option. Without this several of my model objects failed to deserialise

##---------------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.** { *; }

---

If you use the @Expose annotation like I do, you can tell ProGuard to keep any field annotated with it:

# 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 *

---

To exclude your class from obfuscation, Keep the attributes of InnerClasses, keep your class and keep the class members of the class eg.

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

There is a built-in @Keep annotation that you use, please refer this link

Proguard 6.1 cannot handle interfaces with generics in a library. See the bug report here: https://sourceforge.net/p/proguard/bugs/765/
