Android 10 + SD-Card: .../Android/media/[appName] is not created

[philipp.hofmann 5]

Hi,

I'm currently migrating from Delphi 12.1 to Delphi 12.3. I noticed that the directory
.../Android/media/[appName] is no longer created on the SD card (same code, only compiled with Delphi 12.3), at least on my Android 10 tablet. The directory
.../Android/data/[appName] is there.

I can't see any difference in the manifest file (see attachment). The only thing that is also noticeable is that with the Delphi 12.1 version I don't have to call PermissionsService.RequestPermissions for READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE at all and it still works. In the Delphi 12.3 version, I need to call it.

Does anyone know more about it. I've already ordered an Android 13 tablet. If this is only an Android<=10 problem, it might be bearable, but it is still a good 16 percent of users for tablets.

Best regards, Philipp

Thanks to @jaenicke
It's necessary now to ask once for Context.getExternalMediaDirs open the path once and then the directory is created on SD card again.
This was not necessary before.
