Is your storage full?

[fds2610]

thanks for your reply. Nope. 52% used of 64 GB
I installed the app from F-Droid and afterwards from GooglePlay. Both have the same error.

[lordfolken]

Can you provide a logcat?
Also the xcsoar.log would be interesting.

[lordfolken]

No activity. Closing.

Same problem here, in Android 13 TPhone with Google Apps.
No XCSoar folder, No log file found

First Screen when opening the app only shows this Message. I tried apk files from Webpage as well as fdroid.

[lordfolken]

Again. I need to see a logcat. None of my devices seem to have this problem.

[Nati-AS]

Thanks for reopening the issue.

As I didn't know (and couldn't find) how to filter adb output properly here is a filtered logcat made by logcat reader app. I hope everything important is inside.
Especially I get the error:
Failed to set project id on /data/media/0/Android/data/org.xcsoar/: Operation not supported on transport endpoint

If this does not help I can provide another file or more info
logcat_05-14-2024_21-05-22.txt

I supect this means that android cannot set the selinux context on the directory for xcsoar, because the filesystem doesn't seem to support it.

Xcsoar then cannot create any files or directories, because the permissions are incomplete.

Are you by chance using an sdcard?

got the same thought, but I have no idea why. I didn't experience any similar problems with other apps.

No, no sd card in the phone

Can you try the attached pull request, please? This moves all storage to the primary path. @Nati-AS

[lordfolken]

@Nati-AS can you try out the pr?
