Parcelable encountered IOException writing serializable object: java.io.NotSerializableException: org.json.JSONArray

Question

I got this error logout sometimes, I know this logcat means my ABCModel is not serializable but it is. All the model instances which are used inside ABCModel are all serialized,

Here is the complete Logcat:

Probably somewhere in your model contains the JSONArray object. It is not serializable: JSONArray source code
