Android Question String function

[Giusy]

Hi,
I followed the tutorial at this address

https://www.b4x.com/android/forum/threads/string-functions.10365/

Copy the StringFunctions.jar and StringFunctions.xml to the Extra Libraries folder.

I copied them to my "ANDROID LIBRERIE" folder
In "Configure Paths" I have : additional library: C:\ANDROID LIBRERIE
I wrote this code:

Sub Globals
   Dim sf As StringFunctions
   sf.Initialize
End Sub

but "sf" is in red and writes "Are you missing a library reference?

What did I forget?

Thanks

In libraries manager I added "StringFunctions"
Now the error has disappeared, but (for exemple) Dim(....) is in red
Thank you

I guess you did not select the StringUTILS library in the libraries manager

✓ StringUtils(Version 1.12)

 

[samikinikar]

I am late

 

[Giusy]

Yes @samikinikar,
I have also StringUtils(Version 1.12)

I would not use the StringFunctions library, it is no more supported. The author, margret, seems to be inactive in the forum for about three years.
I suggest you to learn to use the 'standard' B4A functions

Hi @klaus
where can I find a tutorial?
Thanks

You may have look at chapter 4.9 String manipulation in the B4X Basic Language booklet.

Hi @klaus
I read the tutorial in point 4.9 but I did not find what I was looking for.
What I have to do is very simple, but not knowing the instructions becomes difficult

I have a string that contain "0001abscd3efgh"
I want to obtain two strings
The first with "0001"
The second with "abscd3efgh"
Every time the first four characters

Help me please

Thank you

Dim s As String = "0001abscd3efgh"
Dim First As String = s.SubString2(0, 4) 'from 0 to 4 excluding the last character
Dim Second As String = s.SubString(4) 'from 4
