        return new Hotel(in);
    }

    public Hotel[] newArray(int size) {

        return new Hotel[size];
    }
};

}

I want to send an arraylist<Hotel> from one intent to another by using i.putExtra("hotels", hotels);

I receive the arraylist<Hotel> by this

ArrayList<Hotel> hotels = (ArrayList<Hotel>) i
                .getSerializableExtra("hotels");

Note that hotels can contain some empty fields.

When I execute, obtain this error:

Let your Hotel class implement Serializable instead of Parcelable.
