How to fix Unmarshalling unknown type code XXX at

Question

I'm having app crash on resume because of Unmarshalling exception. I've checked all the Serializables have constructor with no parameters and even checked all the serializables using ObjectStream (save to file and load from file). How can i understand actual class type for parcelable offset that cause exception:

Saved data consists of Bundles and Serializables and all of them look good.

I'm going to do the next:

try {
// unmarshalling
} catch (Throwable t) {
// look offset 
}

How can i understand what type is actually for Parcelable offset?

Answer 1

It's not Proguard related issue.. But when proguard and minify enable it's issue occurrence is always.

Problem is in sequence of writing and reading of object...sequence should be same, as it is like reading file.

You can use android studio plug in for make class as parcelable https://plugins.jetbrains.com/plugin/7332?pr=

Answer 2

In my case it is fixed after upgrading support library to 23.2.1

Answer 3

In my case it was caused by data size exceeding max limit of that can be put to Parcel which is about 1 MB.

Solution: optimize your Parcelable code to put as less data as possible (e.g. do not put Serializable objects to Parcel)

Answer 4

Just remove all parcelable methods and generate them again with valid sequence

Answer 5

It's because of Proguard obfuscation - it processed Parcelable. solution: Proguard causing RuntimeException (Unmarshalling unknown type code) in Parcelable class

Answer 6

In my case my class don't added CREATOR filed when extending from another Parcelable parent.

public class Image implements Parcelable {
        protected Image(Parcel in) {
        }

        public static final Creator<Image> CREATOR = new Creator<Image>() {
            @Override
            public Image createFromParcel(Parcel in) {
                return new Image(in);
            }

            @Override
            public Image[] newArray(int size) {
                return new Image[size];
            }
        };

        @Override
        public int describeContents() {
            return 0;
        }

        @Override
        public void writeToParcel(Parcel dest, int flags) {
        }
}

public class ImageChild extends Image {
        protected ImageChild(Parcel in) {
            super(in);
        }


        @Override
        public int describeContents() {
            return 0;
        }

        @Override
        public void writeToParcel(Parcel dest, int flags) {
            super.writeToParcel(dest, flags);
        }
}

In ImageChild missing CREATOR field
