Don`t write into sqlite dataBase after previous write

I have some situation. In my expandableListView adapter (BaseAdapter), I have method onDrop to change position of child item by drag.

    public void onDrop(int[] from, final int[] to) {
    if (to[0] > notesList.size() ||
            to[0] < 0 || to[1] < 0 ||
            to[1] > notesList.size() + 1 ||
            (taskList.size()) == to[0] || taskList.size() - 1 == from[0])
        return;
    Note replacedValue = getValue(from);
    Note currentValueOnNewPosition = notesList.get(to[0]).get(to[1]);
    Task task1 = taskList.get(from[0]);
    Task task2 = taskList.get(to[0]);

    int oldTaskName = replacedValue.getTaskName();
    int newTaskName = currentValueOnNewPosition.getTaskName();

    if (currentValueOnNewPosition.getState() == 1L)){
        return;
    } else {
        notesList.get(from[0]).remove(from[1]);
        notesList.trimToSize();

        notesList.get(to[0]).add(to[1], replacedValue);
        selectedGroup = -1;
        selectedChild = -1;

        if (oldTaskName != newTaskName){
            replacedValue.setTaskName(newTaskName);
            int progress1 = getProgress(oldTaskName);
            activity.getDataBaseHelper().changeProgress(task1);
            taskList.get(from[0]).setProgress(progress1);

            int progress2 = getProgress(newTaskName);
            taskList.get(to[0]).setProgress(progress2);
            activity.getDataBaseHelper().changeProgress(task2);
        }
    }

    notifyDataSetChanged();
    activity.getDataBaseHelper().updatePositions(notesList.get(to[0]), activity);
}

in updatePositions(notesList.get(to[0]), activity) i`m write changes to db. It work fine.

  public synchronized void updatePositions(ArrayList<Note> notes, Context context){
    if (isDbClosed()){
        init(context);
    }

    int taskName = notes.get(0).getTaskName();

    db.delete(DataBaseHelper.NOTES_TABLE, " task = ? AND state = 0 ", new String[]{String.valueOf(taskName)});

    for (Note note : notes){
        addNote(note, context);
    }
}

But, after this manipulation, i need to write another changes to dataBase (it happend if I check checkbox, and it write chanded state in asynckTask into DB) and its dont write. It work correctly if I do full reload of activity (database close and open). What I am I doing wrong? Thanks!
