android quicksettings

/frameworks/base/packages/SystemUI/res/values/config.xml

几个重要的设置


    wifi,bt,dnd,flashlight,rotation,battery,cell,airplane,cast

    wifi,cell,battery,dnd,flashlight,rotation,bt,airplane,location,hotspot,inversion,saver,dark,work,cast,night

default

    cell,battery,dnd,flashlight,rotation,location

 

 

前几天碰到一个问题：

WifiSettings UI 里WiFi的状态与quicksettings里的不一致，

WifiSettings UI里始终是对的，状态栏里的WiFi也是对的（打开时就会连上一个AP）。

quicksettings里有时候对 有时候不对，还没有重现步骤， 就是用着不知道怎么就出来了。

有一个肯定是，事先连过一个AP。

由于log基本没有打开，看不出来原因
