Parcelable 写序列化对象遇到IOException [QUICKBLOX DIALOG]
Parcelable encountered IOException writing serializable object [QUICKBLOX DIALOG]
自 4 月 15 日以来，我在 quickblox 中遇到了一个问题，当时 Quickblox 将 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，那么它会抛出下面提到的 IOExeption。否则没问题。
没有问题的对话框。
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}}}
将上述对话框传递给 Activity_chat class
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
接收启动方法Activity
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
}

据我了解，它在对话框中遇到了 JSON 不可序列化的内容，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 class 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 但期望是字符串。最后在获取对话框时添加此行就成功了。
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);
}
}
我的解决方案是排除简单的日期格式：
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();
}
我遇到了同样的问题。相反，现在我的整个项目都受到这个问题的影响。因此，目前我正在使用这种技术，但它并不好，但我们可以使用，后来当他们更新 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 classes 现在都崩溃了。所以现在我要与您分享我的 class 代码块之一。可能对你有帮助。
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;
}
