小米手机后台限制App联网

最近做的app中由一个后台长连接，可能根据具体的业务需求不定时的向用户发送一下通知栏消息，最近有用户反馈没有收到通知栏消息，调试了好久也没有发现什么问题，由于反馈的多是小米手机出现的这个问题，特地从测试哪里拿来一个红米note2调试了一下，期初长连接都是正常的，但是程序退出之后，过了大概五六分钟之后长连接开始不正常，日志显示的错误时：

后台经过查询发现小米手机有一个限制后台运行时联网功能：安全中心-》网络助手-》流量排行榜-》找到自己的应用：

小米不知道为什么将自己的应用后台联网功能关闭了，所以后台的长连接无法保持，查看了一下其他应用，微信，支付宝等都是开启的，不太熟悉小米的算法，而且没有相应的能够打开这个而设置的API，所以暂时没想出什么比较好的办法解决这个问题。
