Prevent class member name obfuscation by ProGuard

Question

I have my class `ClassMultiPoint` with subclasses. ``` public class ClassMultiPoints { public String message; public List data; public class ClassPoints { public String id; public List points; public class ClassPoint { public String speed; public String bearing; } } } ``` I will get value of object `oPoints` from parse `GSON`: `oPoints = gson.fromJson( jsonString, ClassMultiPoints.class);` I try use `oPoints.message`. When I run my application without `proguard` app run success. When I run my app with `proguard` my app crash. I think problem is: `proguard` rename attribute `'oPoints.message'` of my class to short `'a'`. 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* -dontskipnonpubliclibraryclass…

Accepted Answer

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.
