Parcelable Protocol Requires A Parcelable.creator Object Called Creator (i Do Have Creator)

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 EXCEPTION: main 08-31 14:12:22.

Solution 1:

You are have different sequence when reading from Parcel than the one you write in.

In writeToParcel() you are first putting String but in the HeatFriendDetail(Parcel in), you first read integer. It is not the correct way because the order or read/write matters.

Following is the code which makes correct order when writing/reading the data to/from Parcel (also see this link):

publicclassFriendDetailimplementsParcelable {

    private String full_name;
    privateint privacy;

    publicHeatFriendDetail(Parcel in) {
        this.full_name = in.readString();
        this.privacy = in.readInt();
    }

    publicHeatFriendDetail() {

    }

    @OverridepublicvoidwriteToParcel(Parcel dest, int flags) {

        dest.writeString(this.full_name);
        dest.writeInt(this.privacy);
    }

    publicstaticfinal Parcelable.CreatorCREATOR=newParcelable.Creator() {
        public HeatFriendDetail createFromParcel(Parcel in) {
            returnnewHeatFriendDetail(in);
        }

        public HeatFriendDetail[] newArray(int size) {
            returnnewHeatFriendDetail[size];
        }
    };

    // GETTER SETTER//
}

Solution 2:

I received this error in release apk only, because the CREATOR was not public.

I changed this :

staticfinalParcelable.Creator<Station> CREATOR= new Parcelable.Creator<Station>() {

To this :

publicstaticfinalParcelable.Creator<Station> CREATOR= new Parcelable.Creator<Station>() {

Solution 3:

Just ran into this.

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

Normally I declare CREATOR like this:

publicstaticfinalParcelable.Creator<ClassA> CREATOR= 
            new Parcelable.Creator<ClassA>() {

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:

publicstaticCreator<ClassB> CREATOR=
            new Creator<ClassB>() {

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.

Solution 4:

I had this error message when the CREATOR class was not static

Solution 5:

If you are using proguard rules add this line in to your proguard-rules.pro

-keepnames class * implementsandroid.os.Parcelable{
publicstaticfinal ** CREATOR;

}
