android - Parcelable 写序列化对象遇到IOException [QUICKBLOX DIALOG]

Question

自 4 月 15 日以来，我在 quickblox 中遇到了一个问题，当时 Quickblox 将 SDK for android 更新到 2.5.2。 我注意到的问题是，如果我为对话框填充了 customData 参数，那么它会抛出下面提到的 IOExeption。否则没有问题。

不会引起任何问题的对话框。

QBDialog{id=xxxx, created_at=2016-19-04 11:36:54, last_msg_user_id=xxxx, occupants_ids=[xxxx, xxxx, last_message=hey, last_message_date_sent=1461046124, type=PRIVATE, name=xxxx, room_jid=null, user_id=xxxx, photo=null, unread_message_count=0, customData=null}

导致崩溃的对话框。

QBDialog{id=xxxx, created_at=2016-19-04 12:01:00, last_msg_user_id=xxxx, occupants_ids=[xxxx, xxxx], last_message=hello, last_message_date_sent=1461047494, type=PRIVATE, name=xxxx, room_jid=null, user_id=xxxx, photo=null, unread_message_count=1, customData=QBBaseCustomObject{className='DialogueRelationState', fields={isFriends=true, location_field=null}}}

将上述对话传递给 Activity_chat 类的代码段

Bundle bundle = new Bundle();
bundle.getString(selectedDialog.toString());
bundle.putSerializable(Activity_Chat.EXTRA_DIALOG, selectedDialog);
Activity_Chat.start(DrawActivity_Chatlist.this, bundle);// error points here

接收Activity的启动方法

public static void start(Context context, Bundle bundle) {

    Intent intent = new Intent(context, Activity_Chat.class);
    intent.putExtras(bundle);
    context.startActivity(intent); //error points here
}

错误日志:

据我了解，它在对话框中遇到了不可序列化的 JSON，因此出现了错误。

注意:这在 4 月 15 日之前工作正常，我也没有对我的自定义类进行任何更改

我试过将SDK版本从v2.5升级到v2.5.2，但是没有用。

QuickBlox 最近添加了一个 location_field，它返回一个 jsonObject 但期望的是字符串。最后在获取对话框时添加这一行就成功了。

for (QBDialog dialog : dialogs) {
    QBDialogCustomData customData = dialog.getCustomData();
    usersIDs.addAll(dialog.getOccupants());
    if (customData == null) {
        continue;
    }
    HashMap<String, Object> fields = customData.getFields();
    if (!fields.isEmpty()) {
        fields.put("location_field", null);
    }
}
