Caused by: java.lang.IllegalStateException: at android.os.Parcel.createExceptionOrNull

Question

I am getting following exception in production environment. It is related with parcelable classes. But it is not showing which class is problematic. Below is detailed log trace:

This is my Code for Model class using Parcelable:

public class Model implements Parcelable {

String author,language,type,gifFile,binFile;
String downloads,binFileName,gifFileName;
String id;
Timestamp addedon;

protected Model(Parcel in) {
    author = in.readString();
    language = in.readString();
    type = in.readString();
    gifFile = in.readString();
    binFile = in.readString();
    downloads = in.readString();
    binFileName = in.readString();
    gifFileName = in.readString();
    id = in.readString();
    addedon = in.readParcelable(Timestamp.class.getClassLoader());
}

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

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

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

public boolean equals(Object object) {
    if (object != null && object instanceof Model) {
        return ((Model)object).id.equals((Object)this.id);
    }
    return super.equals(object);
}

@Override
public void writeToParcel(Parcel parcel, int i) {
    parcel.writeString(author);
    parcel.writeString(language);
    parcel.writeString(type);
    parcel.writeString(gifFile);
    parcel.writeString(binFile);
    parcel.writeString(downloads);
    parcel.writeString(binFileName);
    parcel.writeString(gifFileName);
    parcel.writeString(id);
    parcel.writeParcelable(addedon, i);
}
}

This is my Code for Proguard-rules files:

-keepattributes Signature

-keep class * implements android.os.Parcelable {
   *;
}

Can anybody help in solving this error?

Answer 1

Android's Timestamp class extends the Date class. And Date class doesn't implement the Parcelable interface. So you cannot read and write the addedon variable. I think that is the problem. You can use long type to store timestamps and then convert it to Timestamp class via setTime(long time) method.

Answer 2

From what I see the problem may be that some of the values are null. I recommend that before you add readString() and readParcelable to add a conditional to make sure that the values are not null.
