Non riesco più a far caricare il file CSV dalla mia app

[Nicola_Imperati]

Salve Taifun, hai perfettamente ragione in riferimento al mio file AIA..richiederebbe troppo tempo per lavorarci sopra.
Comunque la mia versione di android è la numero 11.
Ti allego l'immagine della mia aia.

[Taifun]

I did not ask for all the blocks, I asked for the relevant blocks...
also you forgot to tell us, which error message you get...

Se cambi i nomi dei file da / singolo a // (due slash) e imposti DefaultFileScope a Legacy (in Screen 1 Designer mode) dovresti risolvere il tuo problema.

File Export to csv

you were quite creative in using the new FileScope block... however just putting blocks together randomly does not work... see the following working example [Unbenannt2] save.aia (2.1 KB) tested in the companion app on Samsung A51 running Android 11 note: FileScope Shared did not work while reading the file... [Unbenannt] this most probably is an already known bug @ewpatton? Taifun Trying to push the limits! Snippets, Tutorials and Extensions from Pura Vid…

Ho seguito il suo consiglio, ma non ha funzionato.
Grazie lo stesso.

Salve Taifun,
ho apportato tutte le modifiche alla mia app, tenendo presente i blocchi di codice del file save.aia..ma purtroppo l'errore rimane.

Errore:

[Nicola_Imperati]

Salve Taifun,
in pratica il salvataggio lo effettua e mi crea il file; ma non riesce a leggerlo..e mi dice che il Data Base è inesistente :pensiero: :pensiero: :pensiero:

Please write in English, see also here.

And create a simple test project (aia) that can reproduce the problem.
Also show us the error message.

[Nicola_Imperati]

Anke,
practically with the companion I can both update the file and read it; but after creating the APK, after asking me to allow access to my multimedia files .. it tells me that the Data Base does not exist.

[Nicola_Imperati]

[Anke]

@Nicola_Imperati

it tells me that the Data Base does not exist

Ok, make a screenshot of the message.
But I think I know what happens.

Rename these paths (fileNames) by adding a 2 at the end:

...ListaFilm2.csv
...Backup2.csv

Do not test with Companion, just build the APK and try.

[Nicola_Imperati]

It does not work :non divertito:

[Nicola_Imperati]

Good morning Anke,
despite having followed your advice, unfortunately I cannot solve my problem of reading the CSV file.

[Anke]

Try this (on your Android 11 test device):

saveRead_csv.apk

[Nicola_Imperati]

Anke I tried your APK and it looks like it works. Could you please send me the AIA file?
Thanks
Nicola

[Nicola_Imperati]

Anke,
I followed your advice .. and I inserted instead of "File" -> "AppendToFile", to be able to save chronologically in the csv .. but it gives me this error.

[Taifun]

this is a known bug, see also here including workaround

File Export to csv

So that Taifun's example app (save.aia) also works with the APK, WRITE_EXTERNAL_STORAGE permission must be declared in the Manifest. To do this, set the DefaultFileScope to Legacy in the Designer. This is the only way to achieve this. Do the same with your app. Note: This is of course a bug, which must be fixed (because WRITE permission no longer exists on Android 11). Damit Taifuns Beispiel-App (save.aia) auch mit der APK funktioniert, muss im Manifest WRITE_EXTERNAL_STORAGE permission d…

Finalmente funziona, grazie ad Anke e Taifun per il vostro aiuto prezioso.
