    You need to implement the code to write and read your class fields from parcel.

    In writeToParcel:

    @Override
    public void writeToParcel(Parcel dest, int flags) {
          dest.writeString(st_AcadimicNumber);
          dest.writeString(st_Name);
          dest.writeString(st_Class);
    }
    

    The Parcel CREATOR:

    public static final Parcelable.Creator CREATOR
    = new Parcelable.Creator() {
        public Student createFromParcel(Parcel in) {
            return new Track(in);
        }
    
        public Student[] newArray(int size) {
            return new Track[size];
        }
    };
    

    And the constructor:

    public Student (Parcel source){
          /*
           * Reconstruct from the Parcel. Keep same order as in writeToParcel()
           */
          st_AcadimicNumber = source.readString();
          st_Name = source.readString();
          st_Class = source.readString();
    }   
    

    And it's done.

    Regards
