Error 908: The permision WRITE_EXTERNAL_STORAGE has been denied

[Jose_Luis_Berrueco_R]

Hi, I 'm developing an app with several lists and I was trying to export them to a csv file.
My mobile phone is a Xiaomi MIA3 and it was updated to Android 11.
I have a canvas with several Image Sprites to simulate a hidable menu, and use the Sprites as buttons.
The blocks I use to export the list are the following:

When I click the EXPORT button I get the following error:

I have read several post that say that this error happens with android 11 and that the solution is in the Design set the DefaultScope to Legacy

I have tried this, but the error appears again and I cannot export the list to a csv file

Can somebody help me? Because I do not know how to solve this bug.

Thank you in advance.

Yes, it's a bug and I've pointed it out dozens of times.
Workaround: Set DefaultFileScope = Legacy in the Designer or use my MFile extension (to avoid storage permissions on Android 11+).

@Jose_Luis_Berrueco_R

... the solution is in the Design set the DefaultScope to Legacy

Thank you Anne,

Yes I already set t'he Scope to Legacy because I haver reaf It on one of tour posts.

I haver tries too Taifun's suggestion of t'he ask for permisión method and It didn' to work.

Looking for t'he permisions of t'he app on t'he phone, i can only set to Accés to Multimèdia files.

My monòleg phone has Android One, initially It has t'he Android 9 and It has been upfated Up to Android 11

Thank you very mucho cor tour help.

No, you did not
You have to set the Default File Scope to Legacy in the properties of Screen1 to get the required permissions in the manifest.

What you did is to set the file scope of the file component

Alternatively use the MFile extension which does not need these permissions

MFile - a modified version of Sunny's `EFile` extension - Shared folders - storage permissions - Android 11+

Here is a modified version of Sunny's EFile extension, which added some methods that are needed (among others things) for testing purposes with Companion & AKP. Because if you try to save in one of the Shared folders (/Documents or /Download) first with Companion it is not possible to do this without deleting the saved text file before testing with the APK and vice versa (at least on Android 11+). So the Delete & FileExists & API level methods are needed. The Delete method exists with the File …

Thank you Taifun. I' m Sorry I missunderstood where I should set t'he Scope to Legacy. I' ll teu again and let yo know if finally I succés writing t'he file.

[Jose_Luis_Berrueco_R]

Thank you Anne.
Taifun has made me ser that I missunderstood where I should set t'he Scope to Legacy, i did It on t'he file propietàries and i should haver done un t'he Screen1 propietàries.

i' ll teu again and let you know if finally I succés writing t'he file. If not i'll use tour extension

Thank you Anke,

Finally I've got it, I've set the scope to Legacy in screen1 propierties and set the WTITE_EXTERNAL_STORAGE permision at the Screen1 Initialize and now it works.

Just one question, my mobile phone is set in spanish and I have a default Download folder labelled Descargas, but I have too another one labelled Download at Internal Storage, and here is where the files have been saved. Why are there these 2 folders that are supposed to be the same, but in fact are different?

[Jose_Luis_Berrueco_R]

Thank you Taifun, for clarifying me the mistake I was doing.

Finally I've got it, I've set the scope to Legacy in screen1 propierties and set the WTITE_EXTERNAL_STORAGE permision at the Screen1 Initialize and now it works.
