I have my class ClassMultiPoint
with subclasses.
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;
}
}
}
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:

}

}
-keepclassmembers class * implements android.os.Parcelable {
static android.os.Parcelable$Creator CREATOR;
}
-keepclassmembers class **.R$* {
public static <fields>;
}
What is right way to keep names of the methods and attributes of the my one (static) class?
Obfuscating package names myapplication. MyMain is the main application class that is kept by the configuration. All other class names can be obfuscated. Note that not all levels of obfuscation of package names may be acceptable for all code.
-keepclassmembernames. This is the most permissive keep directive; it lets ProGuard do almost all of its work. Unused classes are removed, the remaining classes are renamed, unused members of those classes are removed, but then the remaining members keep their original names.
You can obfuscate Android code to provide security against reverse engineering. You can use the Android ProGuard tool to obfuscate, shrink, and optimize your code.
If you dont want your class members to be obfuscated then use SerializedName
annotation provided by Gson. For example:
public class ClassMultiPoints
{
@SerializedName("message")
public String message;
@SerializedName("data")
public List<ClassPoints> data;
...
}
Moreover, make sure you do add proper proguard configuration for Gson library too. For example:
##---------------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.
