获取 Android 模拟器的 MAC

启动模拟器， 用adb shell 登陆

用下面的命令可以获取

    # ip link show
1: lo: mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
    link/ether 52:54:00:12:34:56 brd ff:ff:ff:ff:ff:ff
3: sit0: mtu 1480 qdisc noop state DOWN 
    link/sit 0.0.0.0 brd 0.0.0.0

多次启动同一个 avd, 或不同 avd 地址不会变化,  在不同机器上启动 都是这个默认值

尝试对其进行修改，但报告错误，还不知道原因

# ip link set eth0 address 52:54:00:12:34:57
RTNETLINK answers: Device or resource busy

要查看环境变量用

#getprop
