java.lang.RuntimeException: Parcelable encountered IOException writing serializable object in Android passing ArrayList object

Question

I want to pass my ArrayList object to another activity, using a DataWrapper that implements Serializable .
I followed the answer provided here: Pass arraylist of user defined objects to Intent android .
I am starting the another Activity from MPAndroidChart library PieChart 's OnChartGestureListener() . This is how I passed my ArrayList object threadList :

mChart.setOnChartGestureListener(new OnChartGestureListener() {
@Override
public void onChartSingleTapped(MotionEvent me) {
    Intent intent = new Intent(MainActivity.this, TextersSmsActivity.class);
    intent.putExtra("threadList", new DataWrapper(threadList));
    MainActivity.this.startActivity(intent);
}
//.....
}

I implemented the DataWrapper class like this:

public class DataWrapper implements Serializable {
private static final long serialVersionUID = 100L;
private ArrayList<OneThread> threadList;

   public DataWrapper(ArrayList<OneThread> threadList) {
      this.threadList = threadList;
   }

   public ArrayList<OneThread> getThreadList() {
      return threadList;
   }
}

And getting the Parcelable encountered IOException writing serializable object error. Here is my Logcat:

I followed the answer (to pass array list objects) in the link above but getting the Error, what is causing the error and how to remove it?

Answer 1

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