Parcelable encountered IOException writing seriali

I am facing an issue in quickblox since 15th April, when Quickblox updated SDK for android to 2.5.2. The problem that i noticed is like, if i have customData parameter filled for a dialog, then it throws the IOExeption mentioned below. else no issues.

Dialog that casues no issues.

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}

Dialog that causes Crash.

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}}}

Code segment that passes dialogs like above to Activity_chat class

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

start method of the receiving 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
}

Error Log:

what i understand from this is, it encounters something as JSON in the Dialog which is not serializable and hence the error.

NOTE: This was working fine before April 15th, and i have not made any changes to my custom class too

I have tried upgrading SDK version from v2.5 to v2.5.2, but no use.

回答1:

QuickBlox recently added a location_field which was returning a jsonObject but was expecting string. Finally adding this lines while getting dialogs made the trick.

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);
    }
}

回答2:

My solution was exlude simple date format:

 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();
}

I am facing the same issue. Instead now my whole project is effected by this issue. So for the time being I am using this technique which is not good but we can use and latter when they update SDK we can revert our changes in seconds. My all classes which are dependent on QBDialog they are crashing now. So now I am sharing with you one of my class code block. Which may be help full for you.

Crash code:

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
    }
}

Stable code:

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;
    }


}
