现在我想检查一下android设备是否可以通过网络连接到其他设备,我可以使用浏览器登录到互联网,但是当我使用adb shell连接到android模拟器,使用ping命令连接到主机时,它失败了。

kaiwii@ubuntu:~$ adb shell ping 192.168.145.136 PING 192.168.145.136 (192.168.145.136) 56(84) bytes of data. ^C

(192.168.145.136是主机的IP地址!)
但是当我ping www.example.com时127.0.0.1,它工作了。所以,我肯定设备支持ping命令。我只是不明白为什么它不能ping主机,而我可以在浏览器中登录互联网。更重要的是,任何人都可以显示任何其他方法来检查网络能力在android中?
谢谢

亚行 shell ping -c1 www.google.com
如果设备有互联网,将返回以下响应

PING www.google.com (xx.xx.xx.xx) 56(84) bytes of data.
64 bytes from (xx.xx.xx.xx): icmp_seq=1 ttl=61 time=25.3 ms

--- www.google.com ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 25.332/25.332/25.332/0.000 ms

否则

ping: unknown host www.google.com

您是通过手机的数据接口连接到互联网的,而不是通过主机的USB。因此,您的设备和主机之间没有网络连接。此外,由于您的主机没有公共IP地址(它在多级NAT之后,至少有一级是明显的IP),因此设备不可能通过公共互联网ping您的主机。
至于检查网络连接,您可以尝试以下方法:

  • ping www.google.com

输出:

/ $ ping -c1 www.google.com
 PING www.google.com (74.125.236.51) 56(84) bytes of data.
 64 bytes from www.google.com (74.125.236.51): icmp_seq=1 ttl=55 time=40.8 ms
 64 bytes from www.google.com (74.125.236.51): icmp_seq=2 ttl=55 time=47.1 ms
 --- www.google.com ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1001ms
rtt min/avg/max/mdev = 40.850/43.999/47.148/3.149 ms
  • 检查网络连接:busybox ifconfig -a
