下面介绍几种获取app流量的统计规则：
分析方法D
①如何获取uid?
1.先获取进程pid (adb shell ps |findstr 包名)
2.进入到proc/pid/status 文件中
C:\Users\chenhui>adb shell
PD1816:/ $ cd proc/
PD1816:/proc $ cd 20814
PD1816:/proc/20814 $ cd status
/system/bin/sh: cd: /proc/20814/status: Not a directory

PD1816:/proc/20814 $②但是方法D中我们现在的华为、OPPO等高端机中proc系统文件中找不到uid_stat
分析方法E
①方法E中我们现在的华为、OPPO等高端机中proc系统文件中找不到xt_qtaguid
若设备使用的是WiFi，则取第2列的值为“wlan0”的第6列的值相加为当前app的下载流量统计；
第8列的值相加为当前app的上传流量统计

分析方法B
①获取到pid
1.先获取进程pid (adb shell ps |findstr 包名)
2.进入到/proc/pid/net/dev
若设备使用的是SIM联网，则取第1列的值为“rmnet_ipa0”的第2列的值下载流量统计；第10列的值为当前app的上传流量统计
