SUMMARY I’m testing out the new Android beta on my Samsung Galaxy S6 Lite, and at first it was working great, but now I’m getting errors whenever I try to save. Sometimes the error is just a simple “Unknown Error”, other times it’s an “Error occurred while writing to the file”. The file location I’m using is the device local storage, “/storage/emulated/0/Documents/Krita projects/filename.kra”. I created the Krita Projects folder, and I was able to save projects in that location previously, but halfway through working on that project I started getting this error and I can no longer seem to save any projects. STEPS TO REPRODUCE 1. Worked on painting for approximately an hour, had about 6-7 layers 2. Clicked save option, window opened option to save as JPG, which is not what I wanted 3. Went to File > Save As, navigated through file browser and created Krita Projects folder at the location "/storage/emulated/0/Documents", and saved as Krita Project file successfuly. 4. Continued work on project, now offline, autosave worked about twice, then started failing with an unknown error. 5. Attempted saving with the File > Save As menu, same as before, and got an unknown error. Opened a new project and tried saving it, unknown error. 6. Went home and connected to internet, tried working on another new project and using the File > Save As option and got the error "Error occurred while writing to the file" 7. Additionally tried saving as JPG from the shortcut on the top menu bar, same error as step 6. OBSERVED RESULT Have not been able to save for days across multiple new projects. EXPECTED RESULT To be able to save files. SOFTWARE/OS VERSIONS Android: Samsung Galaxy Tab S6 Lite Android 10 One UI version 2.1 Kernel Version 4.14.113.18723785 Krita version 4.3.1-alpha (git 8798b4d) ADDITIONAL INFORMATION The tablet is very new, had little else installed on it at the time of failure and very little customization done to the tablet, aside from changing the device wallpaper and to dark theme it's pretty much stock. I also have not tried reinstalling the application, just in case that actually fixes the issue I wanted to make sure the devs have all the info they need before I get a working app on my tablet again.
Hello! Thanks for the detailed report! Unfortunately, there is no straight way to reproduce this :( So, could you please do these to give us more insight into this bug: 1) Click on Menu (Top Left) > Settings > Dockers > Check "Log Viewer". 2) Log Viewer docker should be created and then you can enable "File loading and saving" and then perform the buggy action. 3) Then you can try to save the log from Log Viewer by clicking save button in it. If it doesn't work, perhaps you can scroll and see some additional relevant info about the error, which you can screenshot and attach?

Created attachment 130341 [details] Krita logs generated while error was occurring I noticed not much was happening on the logs until the error, then it was flooded with permission denied errors as I tried to save or even just navigate my files.

Thanks for the logs! A quick thing which comes to mind from this is if the permission was revoked by the system (I doubt this would happen, but Android docs suggest not to assume anything about system). Could you check if Krita's has been given Storage permission in App Info? https://support.google.com/android/answer/9431959?hl=en

Also as a note, I was able to save successfully 2 or 3 times before the error came in again, it seems like it starts failing after I use Krita for a little bit, like 5-10 minutes, so I don't think it's necessarily a simple storage issue.
I don't see anything permission related in the logs you shared :( If you can either type out one or two errors or screenshot them, please do. I have to see what exactly is denying the permission to find the locus.
Created attachment 130369 [details] Screenshot of in-app logs with permission error Strange that the error wasn't included in the logs. I still had the app open from before, so the screenshot attached are the same errors I was getting while recording the logs last time.
Thanks! Yes, this is certainly a bug. I will try to look into the whole saving mess tomorrow.
