Edit csv file strored in the internal storage of the mobile

Hello everyone,
I'm trying to develope an aplication that edits a csv file previously stored in the internal storege of the device (NOT the SD).
Unfortunatly I recive the message that the file cannot be found.
What is the right way to right a path?
Thenks a lot.

Are you sure you want edit csv file stored in the internal storage ? please be more precise and show your blocks. Documents folder is not in the internal storage.

I whant to write an app that aloud me, once I stored a csv file into a specific folder (DOCUMENTS for ex.) in an android mobile, to edite it scanning a barcode and searching the appropriate "cell".
My first step is to open the stored file. Right now, I always recive the message that the file was not found.
I've tried many ways to write the path, but the massage was always the same.

If the CSV file is newly created (saved) on a device running Android 11+ in one of the Shared folders (like /Documents), there should be no access problems. As soon as something is changed (manually) in the file afterwards, it is then a new file that was no longer created by the app itself. Therefore it can only be accessed with SAF on Android 11+.

You did not show your blocks. Have a look here I cannot save a file in any directory - #21 by patel

Try SAF.

Regardless it would be /Documents/TT.csv

How can I get SAF?
