自4月15日以来，我在Quickblox中遇到问题，当时Quickblox将适用于Android的SDK更新为2.5.2。
我注意到的问题是，如果我为对话框填充了customData参数，那么它将引发下面提到的IOExeption。否则没有问题。
不会出现任何问题的对话框。
QBDialog {id = xxxx，created_at = 2016-19-04 11:36:54，
last_msg_user_id = xxxx，occupants_ids = [xxxx，xxxx，last_message =嘿，
last_message_date_sent = 1461046124，类型= PRIVATE，名称= 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 =你好，
last_message_date_sent = 1461047494，类型= PRIVATE，名称= xxxx，
room_jid = null，user_id = xxxx，photo = null，unread_message_count = 1，
customData = QBBaseCustomObject {className ='DialogueRelationState'，
字段= {isFriends = true，location_field =空}}}
将上述对话框传递给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
接收活动的启动方法
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
}

我从中了解到的是，它在Dialog中遇到无法序列化的JSON形式的错误。
注意：在4月15日之前，它运行良好，并且我也没有对自定义类进行任何更改
我尝试将SDK版本从v2.5升级到v2.5.2，但是没有用。
最佳答案
QuickBlox最近添加了一个location_field，它返回jsonObject但需要字符串。最后，在获取对话框的同时添加此行即可达到目的。
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);
}
}
