Android Calendar Provider不返回最新数据 [英] Android Calendar Provider does not return latest data

问题描述

我正在使用以下代码:

String selection = "((dtstart >= " + now
        + ") AND (dtend <= " + endTime.getTimeInMillis() + "))";
Cursor cursor = context.getContentResolver()
        .query(Uri.*parse*("content://com.android.calendar/events"),
                *PROJECTION*, selection,null, null);

而且我注意到，一旦我在设备上的Google日历应用中添加/删除了Event并立即运行以上代码，偶尔就不会从Cursor获取最新的数据集.我必须手动刷新Google日历应用程序才能获取最新数据.

And I notice that once I add/remove an Event to Google Calendar app on the device and run the above code immediately, occasionally I do not get the latest dataset from the Cursor. I have to manually refresh the Google Calendar app to get the latest data.

我错过了什么吗?我可以使用其他一些API吗?

Am I missing something? Can I use some other APIs?

谢谢！

推荐答案

您是对的.由于某些原因，无论是错误还是功能". -过去4-5个月内，Google日历提供程序只有在与服务器同步后，才通过CalendarContract公开更改.

You are right. From some reasons, whether it's a bug or a "feature" - Google calendar provider in last 4-5 months DOES NOT expose changes via CalendarContract until after they have synced with their server.

在不是这样之前，所有更改都可以通过CalendarContract立即用于第三方应用程序-现在仅在同步之后.这很烦人...除非您在Google日历应用中手动执行同步，否则您永远都不知道自己是否有新数据(或者您可以等到自动同步触发器-可能在几秒钟，几分钟或几小时之内，但不在您的计算机中手).

Before it was not like this, all changes were instantly available for 3rd party apps via CalendarContract - now only after syncing. It is very annoying...You never know if you have fresh data unless you manually perform synchronizing in Google Calendar app (or you can wait until auto-syncing triggers - which can be within seconds, minutes or hours, it is not in your hands).

如此愚蠢，愚蠢的变化.经典Google.他们已经搞砸了很多事情，这只是另一件事.它们只是使开发人员的生活复杂化.

Such a stupid, stupid change. Classic google. They screwed up so many things already, this is just another one. They just complicate life for devs.
