Parcelable objects allow you to serialise and deserialise on activity or fragment stop / start and it is Faster than Java serialisable.

The static CREATOR class creates your object from a Parcel via the createFromParcel method that takes in a parcel and passes it to a constructor in your class that does the grunt work.

The newArray method allows an array of your objects to be parcelled. Answer

And here is a good example of it Link

Parcelable.Creator creates instances of your MyParcelable from a Parcel object. For example the typic Parcelable should look like this :

 public class MyParcelable implements Parcelable {
     private int mData;

     public int describeContents() {
         return 0;
     }

     public void writeToParcel(Parcel out, int flags) {
         out.writeInt(mData);
     }

     public static final Parcelable.Creator<MyParcelable> CREATOR
             = new Parcelable.Creator<MyParcelable>() {
         public MyParcelable createFromParcel(Parcel in) {
             return new MyParcelable(in);
         }

         public MyParcelable[] newArray(int size) {
             return new MyParcelable[size];
         }
     };

     private MyParcelable(Parcel in) {
         mData = in.readInt();
     }
 }
