我似乎无法找到"限制背景数据" 如何工作(启用移动数据)的详细信息。
是什么被认为是"背景" 数据? 例如,如果我发送MMS和手机睡觉,请发送彩信吗?如果我发送彩信并按主页按钮,请发送彩信吗? 是否需要将消息应用程序全部打开,以便发送?如果我正在查看上述应用程序的设置吗?
我已经提出了与MMS有关的问题,但我也想知道一般情况。

I can't seem to find details on how "Restricting background data" works (with Mobile Data enabled) exactly.
What is considered "background" data? E.g., if I'm sending an MMS and the phone goes to sleep, will the MMS be sent? If I'm sending an MMS and press the Home button, will the MMS be sent? Do I need to have the Messaging app open all the time for it to be sent? Is it okay, if I'm looking at the settings of the said app?
I've asked questions pertaining to MMS, but I'm also wondering about the general case.
背景数据是涉及移动数据或Wi-Fi的任何东西;它将使用启用以上(我认为Wi-Fi具有更高的偏好)。这包括AutoSync,背景轮询,通知和将访问移动数据的其他类似操作。
假设您没有在后台运行的任何任务/数据杀手,当您的手机睡眠时,MMS将被发送,您无需打开Messaging App。但是,如果发送失败(经过一定数量的重试),它将失败,并且您必须手动重新发送。
更新#1: autoSync取决于背景数据。如果禁用后台数据,还禁用了AutoSync。 AutoSync由设置中定义的帐户使用(在S4中,<代码> ABCDEFGHIJKLMNABCDEFGHIJKLMN0 )。
但也可以启用背景数据,并且禁用自动同步。在这种情况下,应用程序可以调用并显示通知(例如Twitter)。
Background data is anything that involves mobile data or Wi-Fi; it will use whichever is enabled (I think Wi-Fi has higher preference). This includes autosync, background polling, notifications, and other similar operations that will access mobile data.
Assuming you don't have any task / data killer that runs in the background when your phone sleeps, the MMS will be sent You do not need to have the Messaging app open. However, if the sending fails (after a certain number of retries), it will fail and you will have to resend it manually.
Update #1: Autosync depends on background data. If background data is disabled, autosync is also disabled. Autosync is used by accounts defined in settings (In S4, System Settings > Accounts
).
BUT it's also possible to have background data enabled, and autosync disabled. In this case, apps could poll and show notifications (e.g. Twitter).
