Property would not be serialized into a ‘parcel’

by

Answer:

When a property is not serialized into a ‘parcel’, it means that the property will not be included or stored in the serialization process of the ‘parcel’ object.

Serialization is the process of converting an object into a format that can be stored or transmitted and then deserialized back into an object. In the case of a ‘parcel’, it is an Android-specific concept for passing data between components, such as between activities or fragments.

When creating a ‘parcelable’ object in Android, it is necessary to implement the Parcelable interface and override its methods, including writeToParcel(). Inside the writeToParcel() method, properties of the object are written to the parcel to be serialized and later reconstructed when the object is retrieved.

Example:

// Parcelable object
public class MyObject implements Parcelable {
    private String name;
    private int age;
    private boolean isStudent; // Not serialized into parcel
  
    public MyObject(String name, int age, boolean isStudent) {
        this.name = name;
        this.age = age;
        this.isStudent = isStudent;
    }
  
    protected MyObject(Parcel in) {
        name = in.readString();
        age = in.readInt();
        // 'isStudent' property not read from parcel
    }
  
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeInt(age);
        // 'isStudent' property not written to parcel
    }
  
    public int describeContents() {
        return 0;
    }
  
    public static final Creator CREATOR = new Creator() {
        public MyObject createFromParcel(Parcel in) {
            return new MyObject(in);
        }
  
        public MyObject[] newArray(int size) {
            return new MyObject[size];
        }
    };
}

In the example above, the ‘MyObject’ class implements the Parcelable interface and includes three properties: name, age, and isStudent. However, the ‘isStudent’ property is not serialized into the parcel. This means that when the object is written to a parcel, the ‘isStudent’ value will not be stored and will not be available when the object is later reconstructed from the parcel.
