在Nexus 7上的网络统计信息 [英] Network statistics on Nexus 7

问题描述

我想读我的Nexus 7从文件系统的网络统计数据。在测试前，所有的设备，网络统计数据（例如，tx_packets）总是位于

I want to read the network statistics on my Nexus 7 from the file system. On all devices tested before, the network statistics (e.g., tx_packets) were always located in

/sys/devices/virtual/net/wlan

不过，虽然对的Nexus 7有四个匹配的子目录

However, although on the Nexus 7 there are four matching sub directories

/sys/devices/virtual/net/dummy
/sys/devices/virtual/net/ip6tnl0
/sys/devices/virtual/net/lo
/sys/devices/virtual/net/sit0

他们都不似乎提供正确的统计数据，因为所有的统计文件不会在通过WiFi网络访问更改。

none of them seems to provide the right statistics, as all their statistic files do not change during Web access via WiFi.

任何sugestions，我看起来也？

Any sugestions where I might look as well?

推荐答案

尝试目录：/ SYS /班/网/的 IFACE 的/统计/ tx_packets

try the directory: /sys/class/net/iface/statistics/tx_packets

例如为wlan0 的

long txPackets= 0; //tx Packets
String cmd="cat /sys/class/net/wlan0/statistics/tx_packets\n";
Process p=null;
BufferedReader in2=null;

try {
    p = Runtime.getRuntime().exec(cmd);
    in2 = new BufferedReader(new InputStreamReader(p.getInputStream()));
    txPackets= Long.parseLong(in2.readLine());  
}catch (Exception e)
{
    // TODO: handle exception
    e.printStackTrace();
}
