我有一个地理跟踪应用程序，前端在 PhoneGap 中完成，跟踪是在本机插件中完成的。创建网络连接的插件的唯一部分是当我将位置发布到服务器时，每个帖子小于 1 kB。正如预期的那样，大部分流量是由 HTML+JavaScript 前端完成的。

但是上周我遇到了一个疯狂的问题，我的 Galaxy S4 Mini 报告了大量的背景数据，几个小时内就达到了 500 mb。为了调查这一点，我们开始分析网络流量：我标记了将地理位置发布到服务器的部分，并使用 ddms/monitor 监控流量。大多数情况下，该应用程序的行为符合预期，PhoneGap 完成了一点前台流量，并且每隔一段时间就会有来自插件位置帖子的少量流量。我将应用程序放在后台并继续观看，一小时后突然ddms显示我的应用程序的流量持续 在此处输入图像描述 几分钟后这个流量已经达到了几MB，这似乎是疯狂的数据使用系统报告的原因 在此处输入图像描述

它变得更加奇怪，该应用程序记录了很多，即PhoneGap记录每个javascript执行和html加载等，并且我的插件在收到新位置后立即记录。但是我的应用程序部分没有任何日志记录。唯一不断记录日志的是 NetworkController 通知onDataActivity: direction=X.

有人可以解释一下吗？我一直在尝试重现这种行为，但它没有再次发生，但它仍然困扰着我。
