Congratulations

Some files were read without problems, while others gave me an error message
my PointCoordinates1.csv (238 Bytes)
From which directory did you try to pick the file?
When did it work and when not?
Which Android version are you using for your tests?
To read non media files which have been created by other apps you have to use SAF... to pick one of those files i.e. a text file of your choice from shared storage I think you also can use the filepicker component... I'm not 100% sure, because I did not test this...

app read path and name only and cant read content
Try putting both files in the same directory, do they both work / not work ?
two file are in the same path : / internal storage /DOCUMENTS/
I note that
In the emulator the text in the first file copied and give me
the second file not copied
After exporting apk file and try the two file the same error message for two files
and nothing copied
My guess is that if both files are placed in your ASD, you will be able to open both of them.
Looks like you need to use SAF, if you want to use /Documents with files not created/owned by the app.
The filePicker will get the content uri for the files, but you need to use the SAF extension (or some other SAF method) to open them.
App generate csv file using this block
and i want user to reuse it or open any csv file in his phone
Do your blocks work ?
(If not, it may be better to use Legacy instead of Shared....)
if you store the file with your own app, then later you can access it again easily
however it you stored it with another app, then you need SAF...
everyting is explained here

Yes it work and i can export csv without problems
As you are storing the csv files in your ASD, you also could use the FileList method from the file extension to get a list of your stored files and pick one of them without having to copy them to shared storage...
