Android's default SD card path broken in SFOS 3.2.x [not a question]

There are dangling symlinks WRT the SD-card in SailfishOS:

# ls -l /sdcard
lrwxrwxrwx 1 root root 21 1970-10-18 09:49 /sdcard -> /storage/self/primary
# ls -la /storage
total 8
drwxr-xr-x  2 root root 4096 1970-10-18 08:49 .
drwxr-xr-x 33 root root 4096 1972-03-19 10:16 ..
lrwxrwxrwx 1 root root 7 1970-10-18 09:49 sdcard0 -> /sdcard
#

As /storage/self/primary obviously does not exist, both symlinks point to nowhere!

This seems to be one part of the reason, why many file utilities for Android show a pretty void directory by default (OI Filemanager as an example): OI Filemanager screenshot

But likely some other misconfiguration causes the Android runtime environment to point Android apps to /storage/sdcard0.

Observed with SailfishOS 3.2.0 and 3.2.1 on Xperias.

Sorry, I should have followed my own advice, given at the last paragraph of section 2.2, there.
What happened: SailfishOS 3.2.0 replaced Jolla's original /opt/alien/system/script/platform_envsetup.sh (for the first time since SailfishOS 2.2.0) with an identical file. Hence upgrading to SailfishOS 3.2.0 overwrote these changes I had applied to platform_envsetup.sh and because I missed to reestablish them, I ran into afore-mentioned and -depicted issues.

P.S.: These symlinks seem to be fine and work as they should, but only within the Android runtime environment (AlienDalvik). Thus they "point in circles to nowhere" when looked at outside of the Android runtime environment.

Do you think this observation covers the "Pictures/videos on SD card are not visible to Android apps." issue mentioned here?

I have no idea, which technical issue Jolla intends to address with that statement, it far too "high-levelish".
Note, that this also is not true (technically): With a proper Android file-manager (e.g. OI Filemanager) everything (the whole file-system) is accessible as usual.

Why are you asking / what is your concern?

You have already seen (and commented on) my thread, but I'll link it here in case anyone is interested.

The question "3.2.0.1 on XA2 Dual SIM: SD-Card in Android" might be identical to @svistak's, as already noticed.

To begin by the beginning, i would like that Gallery and Media Jolla Apps can find the encrypt µSD card. To see my pictures i can only use Footo and to listen musics, i can only use Muzik ...

Do you think this issue might be remedied by correcting the symlinks manually? I am eager to try, but don't want to mess up my system even more...

I have no idea what locations ("sources") and which targets these two links really ought to have.

If you do, you may try rectifying them.
Any change executed per rm -i <link name> and ln -s <target> <link_name> can be easily reverted by these two commands, too.

Please report the outcome of your research here.

As I recently discovered, these symlinks are fine and work as they should, but only within the Android runtime environment (AlienDalvik). Thus they "point in circles to nowhere" when looked at outside of the Android runtime environment.

Hi. Does anyone know if there is a solution for SD-card with android applications. Thanks

I also don't understand what happenened, in the times it was possible to read and also save stuff on the sd card, also creating a link to the sd-catd in applications was no problem. Now its like sd-card wouldn't be existing. I know that the Dalvik layer and SFOS are 2 different systems, but if SFOS users can program apps that can exchange data between both systems, Jolla should be able too

Since 3.2.0.12 or 3.2.0.20 (in my case on an XA2) I also can't use the sd card with android apps. In older versions this was easily possible with a change in /var/lib/lxc/aliendalvik/extra_config. I also wrote emails to Jolla customer service, because I thought that the Jolla developer know a solution for this problem but I always got the answer "We are still working on this issue and unfortunately we cannot give any deadlines or SW release number when this would be completed.". Best regards, Uwe.
