Android gpio folder is not available: can't export

In Android for BPI-M64 THE ONLY AVAILABLE FOLDER IS GPIO_SW… What is the way to export/unexport the ports??? How to set the direction?

Well BPI team, why isn’t exist the sys/class/gpio folder in Android 6.0.1??? How to export/unexport??

Now I am building the source, may I change something to can get the sys/class/gpio folder?

Hello,before you build the code,please choose this item,
Device Drivers —> GPIO Support —> /sys/class/gpio/… (sysfs interface)
