Error 2101 with the .APK

[gordonlu310]

Are you using Android 11 or 12? This functionality does not work on these versions.

[gordonlu310]

Also, what exactly is PathLocal?

[David_tesson]

Android 11.
I think I tried with something other than legacy with the companion, but it didn't work. So I left legacy.
What should I put?
The PathLocal variable is "/Documents/Gestion_hand"

[gordonlu310]

Is the file

@David_tesson

/Documents/Gestion_Hand/MEquipe.txt

located in the SD card?

If you are, it is recommended to store the file in the ASD (application specific directory), via Scope > App.

[David_tesson]

No, I haven't SD card. it's on my tablet storage
I tried on compagnon with other than legacy, it's bug.

[gordonlu310]

Why not save it in the ASD?

@David_tesson

No, I haven't SD card.

You do, it is a virtual SD card created by the Android file system, essentially your external storage:

/storage/emulated/0

[David_tesson]

Because I would like to be able to exchange files between several users. It seems easier to me to put all my files in the Media folder of the device.
Here is what the list of my directories returns to me

Set DefaultFileScope = Legacy in the Designer

or use my extension:

Error 908: The permission WRITE_EXTERNAL_STORAGE / bug

UPDATE (Feb 28, 2022): To get rid of the annoying problem / bug "Error 908: The permission WRITE_EXTERNAL_STORAGE has been denied. Please ..." you MUST set DefaultFileScope = Legacy (Designer). Here is versions of an extension, with which both storage permissions (READ & WRITE) are declared in the Manifest, independent of the components used (especially the File component). It declares READ & WRITE on all Android versions (also incorrectly on Android 11+, but NOT with AI2 - for whatever re…

@David_tesson

No, I haven't SD card.

[David_tesson]

scope is already on legacy
I tried your extensions. Both versions give me error 908

[Anke]

Post the aia or send it to me via PM (privately).

[David_tesson]

I send you my AIA in PM
Many thanks

[Anke]

@David_tesson You did NOT set

@Anke

DefaultFileScope = Legacy in the Designer

and you did also not use the first version of my extension.

[David_tesson]

I did so many tests by changing things everywhere, and I forgot to put things back. sorry

I download, built and installed ReadWrite_ExtVer1.aiak and ReadWrite_ExtVer2.aia. Both: Error 908

in your AIA FileScope is on "APP" you have to put it on "legacy" ?

[David_tesson]

I hage put your extension in my app. i set Defaultscope = Legacy in designer.
I no longer get the 908 error on startup. But after searching for MEquipe.txt files, I still get error 2101.

@David_tesson

I still get error 2101

If the File was created by Companion before you try to test with the APK, it does not work, because the file was created by another app and no longer be overwritten / accessed by a new app (on Android 11+).

Two options:

• delete the file via Companion before closing Companion or
• the file name must be different with Companion and APK.

Using storage scope type app to share data between screens

This one doesn't work with Companion and the compiled APK on Android 11+ as it doesn't delete the text file when Companion or the APK is closed. Therefore, after testing with Companion, the file cannot be overwritten via the APK and vice versa. So either you do not test with Companion or delete the file via Companion before closing Companion or the file name must be different with Companion and APK. Note: If the user uninstalls and reinstalls the app it does not work anymore, because the…

Arghhh !
It's not too bad that the files created by the companion do not work with the APK because once finished the app will generate its own files.
On the other hand, I thought I could create some CSV with EXCEL and transfer them to the directories, will it bugg too?
I would also like team leaders to be able to exchange CSV files. they will be created by the same app but not on the same device. will it crash?
How does Android know who created the file?
Many thanks Anke

@David_tesson

How does Android know who created the file?

Good question. I think Google (Android) doesn't know who created other files with the same file name, but it only knows if the file is / was created by your app or not.
