android下调试程序两个好用的命令watchprops和svc

1). watchprosp 动态监视android系统属性的变化，有变化就会输出:

root@android:/ # watchprops
1362449042 persist.sys.autolanguage = 'on'
1362449044 persist.sys.autolanguage = 'off'

2). svc ，控制power, wifi, modem状态。

Available commands:
help     Show information about the subcommands
power    Control the power manager
data     Control mobile data connectivity
wifi     Control the Wi-Fi manager

svc power

usage: svc power stayon [true|false|usb|ac]
Set the 'keep awake while plugged in' setting.//设置屏幕的常亮，true保持常亮，false不保持，usb当插入usb时常亮，ac当插入电源时常亮

svc data

usage: svc data [enable|disable]
Turn mobile data on or off.//设置移动网络的数据是否启用
Set mobile as the preferred data network//设置移动网络的数据优先于WIFI

svc wifi

usage: svc wifi [enable|disable]
Turn Wi-Fi on or off.//设置WIFI是否启用
Set Wi-Fi as the preferred data network //设置WIFI优先于移动网络的数据，一般应设置成这样，除非你刻意使用移动网络数据传输
