android adb查看网络连接情况
文章目录
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
10500: from all iif lo oif wlan0 uidrange 0-0 lookup wlan0

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