emergency config export fails

[balihb]

Clicking the emergency expot button gives a nondescriptive error (with a suggestion to look for it in logcat). The message I found in logcat:
Failed to export config. Could not determine app's private files directory on external storage.

The directory /storage/emulated/0/Android/media/com.github.catfriend1.syncthingandroid is created, but empty.

Hi,

what is your absolute path to the internal storage root? I've got /storage/emulated/0 .

[balihb]

same: /storage/emulated/0/Android/media/com.github.catfriend1.syncthingandroid looks like thecode expects, that I have at least two drive and removes 0 from the list, so it ends up with an empty list. I can't figure out why. wouldn't it be better to just choose the last drive fromthe list (which is not null)?

[Catfriend1]

The question (from my mind) is , the last drive could be an external sdcard where prior Android 11 the export never worked because of SAF requirements. Will re-check this when I have more time and on PC.

Could you try to get root for this? At least some people would then have a possibility to workaround this.

Solved by #787 (We now got all files access on Android 11.) If it does not solve the storage root detection, I honestly don't know why it fails on some rare makes and models.
