Android 使用adb查看网络使用情况主要的adb命令：

adb shell ifconfig //查看配置信息

adb shell dumpsys connectivity //查看连接情况

db shell netstat //查看连接状态和地址

adb shell ip ru //查看路由策略

下面展开说一下几个命令输出后的数据如何分析或者查看。

1、adb shell ifconfig

输入命令，获取到如下信息：

C:\Users\liwenzhi>adb shell ifconfig

上面表示已经打开的连接端口/网卡名称，如果没有打开是看不到的比如：只有wifi开启状态才显示wlan0这项

这里一般关心wlan0（wifi）和eth0（有线网络）

如果连接成功inet addr会显示具体ip地址

其中inet addr：表示连接成功后的ip地址，如果没有连接成功，是没有的。

2、adb shell dumpsys connectivity

这个打印的内容是比较多的，看重点地方即可。

简单的说，就是连接上网络后Current Networks才看到相关信息 ip地址，网络的Score分值（分值越高越优先，一般针对优先网络和wifi的切换）等信息

具体情况如下图如所示：

总结就是注意看Current Networks项里面的内容即可。

部分信息：

Active default network: 101

Current Networks:

我这里是在系统中注释了网络切换后网络释放的操作，所以Current Networks才会有多个网络（正常是只看到一个NetworkAgentInfo网络对象的）

但是系统默认连接的只有一个那就是Active default network的网络

从NetworkAgentInfo也可以体现出现，那就是NetworkRequest的Capabilities包含INTERNET标签；还有就是包含REQUEST id=1 这个基本就是当前正在使用的网络

有些设备需要支持wifi和有些网都能连通，就不能释放网络。app内可以进行不同网络的选择连接。

3、adb shell netstat

用得不多，可能是查看连接过的具体网址

注意是看上面tcp的信息

Address是本机的信息。

Foreign Address是访问的地址信息。

打印情况如下：

C:\Users\liwenzhi>adb shell netstat

3、adb shell ip ru

C:\Users\liwenzhi>adb shell ip ru

0: from all lookup local

10000: from all fwmark 0xc0000/0xd0000 lookup legacy_system

10500: from all iif lo oif dummy0 uidrange 0-0 lookup dummy0

10500: from all iif lo oif eth0 uidrange 0-0 lookup eth0

22000: from all fwmark 0x0/0xffff iif lo lookup wlan0

32000: from all unreachable

这里是路由策略，应该是和NetworkAgentInfo里面的NetworkRequest有一定的关联

路由策略是可以进行设置的，就是通过adb禁止/允许网络的使用（wifi/有线网络）。

但是路由策略需要root权限！设备默认root或者adb root成功才行。

adb shell ip ru flush //清空所有的路由表 adb shell ip ru add from 192.168.13.X/24 lookup eth0 //把内网设置成以太网 adb shell ip ru add from all lookup wlan0 //添加wifi联网 adb shell ip ru del from XXX //删除某一个路由策略

下面是一组简单的操作示例：

C:\Users\liwenzhi>adb shell ip ru

0: from all lookup local

10000: from all fwmark 0xc0000/0xd0000 lookup legacy_system

10500: from all iif lo oif dummy0 uidrange 0-0 lookup dummy0

10500: from all iif lo oif eth0 uidrange 0-0 lookup eth0

10500: from all iif lo oif wlan0 uidrange 0-0 lookup wlan0

13000: from all fwmark 0x10063/0x1ffff iif lo lookup local_network

13000: from all fwmark 0x10064/0x1ffff iif lo lookup eth0

13000: from all fwmark 0x10065/0x1ffff iif lo lookup wlan0

14000: from all iif lo oif dummy0 lookup dummy0

14000: from all iif lo oif eth0 lookup eth0

14000: from all iif lo oif wlan0 lookup wlan0

15000: from all fwmark 0x0/0x10000 lookup legacy_system

16000: from all fwmark 0x0/0x10000 lookup legacy_network

17000: from all fwmark 0x0/0x10000 lookup local_network

19000: from all fwmark 0x64/0x1ffff iif lo lookup eth0

19000: from all fwmark 0x65/0x1ffff iif lo lookup wlan0

22000: from all fwmark 0x0/0xffff iif lo lookup wlan0

32000: from all unreachable

可以自己测试一下，删除所有路由策略发现wifi上不了网，把wifi策略添加后就可以上网了。

总结一下：

比较简单易懂在是： adb shell ifconfig //查看配置信息比较全面在信息是： adb shell dumpsys connectivity //查看连接情况
