通过ProGuard防止混淆类成员名称

我的班ClassMultiPoint有子班。

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oPoints将从解析中获得对象的价值GSON：

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

我尝试使用oPoints.message。

当我运行我的应用程序而没有proguard运行成功时。当proguard我的应用崩溃时运行我的应用时。

我认为问题是：proguard将'oPoints.message'班级的属性重命名为short 'a'。

我尝试保持方法和属性的名称不变，但是proguard将其重命名：

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>;
}

保留第一个（静态）类的方法和属性的名称的正确方法是什么？

感谢Waqas！

我为我的情况找到了解决方案：

-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$ClassMultiPoints$ClassPoints { public protected *; }
