This program is designed to switch tracks in the player is running and off the device screen by double clicking on the volume button.
The program allows you to choose your preferred delay between clicks.
To switch to the next track you need to make two clicks on the "volume up" with a delay of no more than specified in the "Delay". Accordingly, previous track - "volume down".
!!! The program works only when the play player and the screen turns off. Krosfeyd in the player must be disconnected. Probably does not work on runoff firmware HTC (disable a smooth change in the volume, if possible) !!!
Can not work with some devices.
Added Duble Click if Screen On
