ProGuard for Android and GSON

I think most of those settings you have there are already included in the Android SDK by default.

So you can remove most of them, just leaving in the section devoted to GSON.

I am developing in Eclipse using Android SDK Tools 22.6.3 & whatever version of ProGuard ships with that.

Here’s what I’m using for GSON 2.2.4 (as per their 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

# Gson specific classes
-keep class sun.misc.Unsafe { *; }
#-keep class** { *; }

# Application classes that will be serialized/deserialized over Gson
# -keep class** { *; }

It looks exactly the same as what you have, except I don’t need the line about the annotations.

You can see I’ve commented out some classes that I added myself. If you serialize/deserialize your own classes, you need to declare them here in place of the reference to This is really important, as you don’t want ProGuard to obfuscate the field or class names that GSON uses for serialization.

I always leave those types of comments in there, so I know how to configure the next library or app.
