1. You really should give the Thread a useful title. "pdf" is a bad Subject.

2. You can do this with B4J using PDFBox7

PDFBox (beta). Editing PDF AcroForm Fieldvalues, creating PDFs with new AcroForm

This is a partial wrap for Apache PDFBox. In this early stage i am focusing on manipulating PDF AcroForms and building new PDF with AcroForm. It is also possible to create some javascript which can run when you open the PDF on acrobat. The Examplecode and the needed Objects i got my...

www.b4x.com

As far as i know it is not possible in B4A

you need to use FileProvider if you want to share a pdf with adobe reader on android.

But even if you get it working you´ll run into another problem. How would you get the pdf after the user has edited the AcroForm PDF with AcrobatReader? The user only can save the PDF as a new copy. You´ll get no info about where he stored the new PDF.

I would use a jServer App (B4J), send the csv-Data to the server, combine formular and csv-Data into a new pdf (using PDFBox) and return the PDF back to the calling app (B4A)

oh, you are right.
it is not as of the PC site -> save as (chipnumber.pdf)
open a Formular.pdf (original), edit and then save as chipnr.pdf (276094100290524.pdf)
i want save in File.DirInternal. the app store the chipnumber in a csv (chipnr, name, date)
On a click in the table, get the chipnumber as string and expand it to "chipnr.pdf" (276094100290524.pdf)
so you can re open the pdf or send to PC.

this was my idea.

You can do this in AdobeReader (save as xy.pdf) but your app does not know the new filename and path of the edited pdf. How you´ll get it?

AGAIN (the 3rd and last time):
You do NOT GET the filename and even not the path the user saves the newly generated PDF in. The user can not save it to your Apps DirInternal as he has no access to this folder.
You do not have any control over the path and filename.

You only have control before you open that pdf with acrobat (Path and filename). But not the same on the edited PDF.

OK.
Then i send the data or csvfile to my PC
and create a new pdf on my PC.
