Parcelable protocol requires a Parcelable.Creator object called CREATOR (I do have CREATOR)

Question

I am trying to pass Parcelable data from one intent to another and this is the error I am getting:

08-31 14:12:22.709: E/AndroidRuntime(9931): FATAL EXCEPTIO         


        

Answer 1

Just ran into this.

I had a hunch, and I looked in my ProGuard mapping file.

Normally I declare CREATOR like this:

    public static final Parcelable.Creator CREATOR = 
            new Parcelable.Creator() {

which shows up in the mapping file like this:

    android.os.Parcelable$Creator CREATOR -> CREATOR

..except for one class, the class that was reported with the error. I declared it like this:

    public static Creator CREATOR =
            new Creator() {

Lo and behold:

    android.os.Parcelable$Creator CREATOR -> a

So if you are getting this exception in your production release, check your mapping file. I think ProGuard is really sensitive to how CREATOR is declared when deciding not to obfuscate it.
