OSError: [Errno 38] Function not implemented

in settings.py add : 

STATIC_URL = 'static/'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static')
]
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

then run command python manage.py collectstatic you will get this OSError

Steps to reproduce the behavior.

I figured it out,django file handling works on home dir but not on other dir because of Android os
