Android 无法从Facebook SDK、Graph API获取所有通知

我正在制作一个应用程序，我需要从Facebook获得所有新的通知。我成功登录并获得应用程序的管理通知权限。这段代码成功地从facebook加载了JSON字符串

Session session = Session.openActiveSessionFromCache(ctx);
    if (session != null && session.isOpened()) {
        Request notificationsRequest = Request.newGraphPathRequest(
                session, "/me/notifications",
                new Request.Callback() {

                    @Override
                    public void onCompleted(Response response) {
                        GraphObject object = response
                                .getGraphObject();
                        if (object != null) {
                            notificationsNewString = object
                                    .getInnerJSONObject()
                                    .toString();

                            try {
                                notificationsOldString = saver.getJsonFromInternalCache();
                            } catch (IOException e) {
                                notificationsOldString = null;
                            }
                            try {
                                compareOldAndNewData();
                            } catch (ParseException e) {
                                e.printStackTrace();
                            }

                            createNotif();

                        } else {
                            notificationsNewString = "Notifications returns null";
                        }

                    }
                });
        Request.executeBatchAndWait(notificationsRequest);
    } else {
        Log.i("TAGTAG", "Session not open!");
    }

但有些人在应用程序上有困难，因为Facebook不会发送所有新的通知。特别是当有人评论他们评论的状态时通知。（在Facebook上，它被标记为一个新通知，但json是空的）

是关于一些权限还是它是bug

谢谢。

我找到了另一种方法。我会把它贴出来，以防有人觉得有用

private void onSessionStateChange(Session session, SessionState state, Exception exception) {
if (state.isOpened()) {
    InboxMessage.setVisibility(View.VISIBLE);

    new Request(session,"/me/notifications", null,HttpMethod.GET,new Request.Callback() {

                public void onCompleted(Response response) {
                    GraphObject object = response.getGraphObject();
                        if (object != null) {
                            InboxMessage.setText(object.getProperty("data").toString());
                        } else {
                            InboxMessage.setText("Notifications returns null");
                        }
                }
            }
        ).executeAsync();
} else {
    InboxMessage.setVisibility(View.INVISIBLE);
    Log.i(TAG, "Logged out...");
}
}

您好，我有同样的问题，我已经创建了一个错误报告：
