APK：ethernet广播监听以太网状态、ping外网、广播监听wifi的状态
一.LAN/WAN/WLAN/WWAN区别总结
LAN: Local Area Network : 局域网
WAN: Wide Area Network, 广域网
WLAN: Wireless LAN, 无线局域网
WWAN: Wireless WAN: 无线广域网
二.以太网监听广播

}
}
}
三.节点判断以太网插拔状态 cat /sys/class/net/eth0/carrier
四.ping 外网
public static final boolean ping() {
String result = null;
try {
String ip = "www.baidu.com";
Process p = Runtime.getRuntime().exec("ping -c 3 -w 100 " + ip);
int status = p.waitFor();
if (status == 0) {
result = "success";
return true;
} else {
result = "failed";
}
} catch (IOException e) {
result = "IOException";
} catch (InterruptedException e) {
result = "InterruptedException";
} finally {
Log.d("gatsby", " ping result = " + result);
}
return false;
}
五.wifi网卡状态、操作网卡的权限
5.1.wifi网卡状态
a.WIFI_STATE_DISABLED:WIFI网卡不可用
b.WIFI_STATE_DISABLING:WIFI正在关闭
c.WIFI_STATE_ENABLED:WIFI网卡可用
d.WIFI_STATE_ENABLING:WIFI网卡正在打开
e.WIFI_STATE_UNKNOWN:未知网卡状态
