Wifi On/Off

小應用程序切換無線開/關。

Small application to toggle wifi on/off.

There are so many available widgets that you can use; however in Android 4.1 (and higher versions) phones, you can not add one of these widgets to the launcher lower line of icons (see screen-shots).

This application can be added to that line of icons so it is accesible in any of the screens and you don't have to swipe the whole screen to find shortcuts.
