Question

我从4月15日开始在quickblox中遇到一个问题，当时Quickblox将SDK for android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，那么它会抛出下面提到的IOExeption。别的没问题。

不会出现问题的对话框。

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，type = PRIVATE，name = xxxx， room_jid = null，user_id = xxxx，photo = null，unread_message_count = 0， =的CustomData空}

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，type = PRIVATE，name = xxxx， room_jid = null，user_id = xxxx，photo = null，unread_message_count = 1， =的CustomData {QBBaseCustomObject =的className＆＃39; DialogueRelationState＆＃39 ;, fields = {isFriends = true，location_field = null}}}

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

启动接收活动的方法

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
}

我从中理解的是，它在Dialog中遇到了一些不可序列化的东西，因此也就是错误。

注意：这在4月15日之前运行正常，我也没有对我的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，但没有用。

Answer 1

QuickBlox最近添加了一个location_field，它返回一个jsonObject但是期待字符串。最后在获取对话框的同时添加这些行就可以了。

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);
    }
}

Answer 2

我的解决方案是简单的日期格式：

 public static void setGroupDialog(QBDialog qbDialog) {
    GsonBuilder builder = new GsonBuilder().setExclusionStrategies(new ExclusionStrategy() {
        @Override
        public boolean shouldSkipField(FieldAttributes f) {
            return f.getName().equals("sdf");
        }

        @Override
        public boolean shouldSkipClass(Class<?> clazz) {
            return false;
        }
    });
    String json = builder.create().toJson(qbDialog);
    getAuthPreferences(YOUR_APP_CONTEXT).edit()
            .putString(PREF_GROUP_DIALOG, json).commit();
}

我面临同样的问题。相反，现在我的整个项目都受到这个问题的影响。所以目前我正在使用这种技术并不好，但我们可以使用，后者在更新SDK时我们可以在几秒钟内恢复我们的更改。我所有依赖于QBDialog的类现在都崩溃了。所以现在我和你分享我的一个类代码块。这可能对你有所帮助。

崩溃代码：

public class ChattingActivity extends ... {


    public static final void start(Context context, QBDialog qbDialog)
    {
            Intent intent = new Intent(context,ChattingActivity.class);
            intent.putExtra(Intent.EXTRA_STREAM, qbDialog); 
            context.startActivity(intent); // Crash when try to start
    }
}

稳定的代码：

public class ChattingActivity extends ... {

    private static QBDialog QB_DIALOG;

    public static final void start(Context context, QBDialog qbDialog)
    {
            Intent intent = new Intent(context,ChattingActivity.class);
        //  intent.putExtra(Intent.EXTRA_STREAM, qbDialog);
            ChattingActivity.QB_DIALOG = qbDialog;
            context.startActivity(intent); // Crash when try to start
    }

    // Important: Should do null in OnDestroy.
        @Override
    protected void onDestroy() {
      super.onDestroy();
      QB_DIALOG = null;
    }


}

Parcelable遇到IOException，编写可序列化对象[QUICKBLOX DIALOG]
