Parcelable encountered IOException writing serializable object getactivity()

so I am getting this in logcat:

java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = com.resources.student_list.Student)

I know this means that my student class is not serializable, but it is, here is my student class:

import java.io.Serializable;


public class Student implements Comparable<Student>,  Serializable{

    private static final long serialVersionUID = 1L;
    private String firstName, lastName;
    private DSLL<Grade> gradeList; 

    public Student() {
        firstName = "";
        lastName = "";
        gradeList = new DSLL<Grade>();
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public DSLL<Grade> getGradeList() {
        return gradeList;
    }

    public void setGradeList(DSLL<Grade> gradeList) {
        this.gradeList = gradeList;
    }

    public int compareTo(Student arg0) {
        return this.lastName.compareTo(arg0.getLastName());
    }

}

and this is the code that is using the getIntent() method:

public void onItemClick(AdapterView<?> parent, View viewClicked, int pos,
                                long id) {

                            Student clickedStudent = studentList.get(pos);
                            int position = pos;
                            Intent intent = new Intent(getActivity().getApplicationContext(), ShowStudentActivity.class);
                            Log.e("CINTENT","CREATED!!!");
                            intent.putExtra("clickedStudent",clickedStudent);
                            intent.putExtra("newStudentList",newStudentList);
                            intent.putExtra("position",position);
                            Log.e("putExtra","Passed");
                            Log.e("Start activity","passed");
                            startActivity(intent);

                        } 

                    });

please help me figure out whats wrong with this.

here is the whole LogCat:

Solution 1:

Caused by: java.io.NotSerializableException: com.resources.student_list.DSLL$DNode

Your DSLL class appears to have a DNode static inner class, and DNode is not Serializable.

Solution 2:

Your OneThread Class also should implement Serializable. All the sub classes and inner sub classes must implements Serializable.

this is worked for me...
