Error on using proguard with Android Facebook sdk 3.0

Question

Warning: I removed a lot of \"old text\" to keep the question more clean. Just check the history if needed.

I\'m using proguard to both

Answer 1

Try

-keep class com.facebook.** {
   *;
}

The reason being, is that when specifying private, public, protected you're still opening up default (package private) access to obfuscation.

Answer 2

This may work (untested)

-keep class com.facebook.** { *; }

Answer 3

if you want to proguard Facebook, the config below is working for me

#modify for Facebook
-keepattributes Signature
-keep class com.facebook.model.** { *; }

-keepnames class * implements java.io.Serializable
-keepclassmembers class * implements java.io.Serializable {
    static final long serialVersionUID;
    private static final java.io.ObjectStreamField[] serialPersistentFields;
    !static !transient <fields>;
    private void writeObject(java.io.ObjectOutputStream);
    private void readObject(java.io.ObjectInputStream);
    java.lang.Object writeReplace();
    java.lang.Object readResolve();
}

Answer 4

This will solve your problem, i hope:

And the winner is .....

-keepattributes Signature

From Proguard Homepage:

The "Signature" attribute is required to be able to access generic types when compiling in JDK 5.0 and higher.
