I cant understand.
Why regex cant split "." / POINT


B4X: 
Dim d() As String
    d=Regex.Split(".","192.168.1.31")
    Log(d.Length)
'************
' RETURN : 0
'***********

B4X: 
Dim d() As String
    d=Regex.Split(",","192,168,1,31")
    Log(d.Length)
'************
' RETURN : 4
'***********

"." ist one of some reserved characters that have functions in regex-definitions. If you want to split by these characters you have to mask them with "\".
B4X: 
regex.split("\.","a.b.c.d.e.f.g")
