title: Parcelable encountered IOException writing serializable object getactivity()
body: <p>so I am getting this in logcat:</p>
  
  <pre><code>java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = com.resources.student_list.Student)
  </code></pre>
  
  <p>I know this means that my student class is not serializable, but it is, here is my student class:</p>
  
  <pre><code>import java.io.Serializable;
  
  
  public class Student implements Comparable&lt;Student&gt;,  Serializable{
  
      private static final long serialVersionUID = 1L;
      private String firstName, lastName;
      private DSLL&lt;Grade&gt; gradeList; 
  
      public Student() {
          firstName = "";
          lastName = "";
          gradeList = new DSLL&lt;Grade&gt;();
      }
  
      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&lt;Grade&gt; getGradeList() {
          return gradeList;
      }
  
      public void setGradeList(DSLL&lt;Grade&gt; gradeList) {
          this.gradeList = gradeList;
      }
  
      public int compareTo(Student arg0) {
          return this.lastName.compareTo(arg0.getLastName());
      }
  
  }
  </code></pre>
  
  <p>and this is the code that is using the getIntent() method:</p>
  
  <pre><code>public void onItemClick(AdapterView&lt;?&gt; 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);
  
                          } 
  
                      });
  </code></pre>
