Android命令行获取WiFi列表以及参数
Android如何通过命令行获取WiFi列表以及参数：
一个工具加一个参数：
wpa_cli => The command line interface of wpa_supplicant
wifi interface socket目录
一般Android习题WiFi所对应着的interface名为wlan0，若不一样请参看init.{xxx}.rc中启动wpa_supplicant daemon的参数，或通过getprop查询得到。
找到带有wlan0 socket文件的目录，比如
/data/misc/wifi/
在我的手机上（Android 4.2.2）为/dev/socket/
然后adb shell
通过-p 选项指定socket文件目录
