Dim str As String = "abc|def|efg"
Dim x() As String = Regex.Split("\|", str)
For Each s In x
    Log(s)
Next

untested: regex.split("\x7c",str)
?

why not:

B4X:

Dim str As String = "abc|def|efg"
Dim x() As String = Regex.Split("|", str)
For Each s In x
    Log(s)
Next

The pipe character has a special meaning in regex so it needs to be escaped.

I couldnt get this to work either.

I ended up having to do this:

B4X:

Dim ResponseArray() As String = Regex.Split("[|]", ResponseString)

This code works correctly. I've just tried it. The output is:

B4X:

Sub Activity_Click
    Dim str As String = "abc|def|efg"
    Dim x() As String = Regex.Split("\|", str)
    For Each s In x
        Log(s)
    Next
End Sub

efg

ok ill have to check the string coming from the server then to see if something is wrong with that. Maybe ill need to run some regex thing to clean up non printable characters.
