"Can't write to a file!" again
for some time I cannot share fieldNotes.txt. At first it stooped work with OneDrive after about a year or more with Google Disk, too. So I fell back to using Store offline ("Offline úložiště" in Czech) and manually sharing it using Google Disk. Yesterday it stopped working, too.
I googled and find "solution" - https://help.locusmap.eu/topic/fieldnotes-chyba-zápisu-do-souboru. I've looked for 188.8.131.52 APK, installed it, but the problem haven't changed.
Today I started to investigate again. Application has been auto-updated over the night, but I don't think it worsened the problem.
I started ADB and looked at the logs. At first I started in the "Add timestamp to file name" mode, the checked the option off and tried again. I tried both operations, "Store offline" and "Share". Then I changed language in my phone from Czech to English (it solved problems I've got with Kindle for Android some time ago) and tried again.
Although both operations produced the same message on the phone screen, "Nastala chyba při zápisu do souboru!" resp. "Can't write to a file!", only "Store offline" produces corresponding loggings.
I'm attaching the logs (for Czech locales only) and screenshots.
- Two of the screenshots might look identical, but one has been saved after touching "Offline úložiště" and the other after touching "Sdílet".
- You can also see, that I looked for Field Notes application PID, I used it to filter only the related lines.
- At the end you can find listing of the problematic folder.
If it were on regular Linux and I, as its owner, could impersonate as root, I would simply add u0_a486 user (the Locus FieldNotes owner) to sdcard_rw group or change folder's permissions to allow writes to anybody, and problem would be solved (I've actually tried the chmod, but nothing happened, not even an error has been printed).
The last information - I have Locus Map 3 Classic and also Locus Map 4 applications installed in "shared" configuration.
As the application owner is said to be unresponsive, I hope maybe someone of you could devise a way how to grant missing permission to the Locus FieldNotes add-on/application.
