Script crashes when exporting contacts

[Poomex]

As in the title, apps export correctly but it crashes after this message:

Exporting contacts (as vCard).
adb: error: failed to stat remote object '/storage/emulated/0/linux-android-backup-temp': No such file or directory

log.txt

What Android version are you on? Also, have you pressed the "Export Data" button in the companion app before letting the script continue?

[Poomex]

Android 10 (Havoc OS 3.7). Yes I have, I pressed the button and then continued the script with enter.

Do you have any experience with Android app development? I can't reproduce this on my side, so you'd have to install Flutter and Android Studio, build a debug .apk and use the built-in debugger to get error logs. A video or screenshots could be also helpful.

P.S. Możemy porozumiewać się po polsku :)

Unfortunately I don't, but if you were to build such an apk I could install it and get the logcat from it. Would that work? P.S. dla dobra innych użytkowników którzy mogą mieć ten sam problem może pozostańmy przy angielskim ;)

android:maxSdkVersion="28" from https://github.com/mrrfv/linux-android-backup/blob/673728da1d991e7fea2696810d9a1cab1603487b/companion_app/android/app/src/main/AndroidManifest.xml#L6
is wrong for me and returns errno 13 on create directory.

ps api29 phone
ps2 not sure, but seems this line required for api29 and above...
I was wrong.
MANAGE_EXTERNAL_STORAGE required from api30 and above.
But WRITE_EXTERNAL_STORAGE was required(according to manifest) for api28 and earlier.
So for api29 no write permission was requested in manifest.

I built 2 debug APKs - one with no changes, and one with android:maxSdkVersion set to 29. Let me know if the second debug APK resolves the issue.

The debug version worked for me. But I had to replace the .apk built by the script with the debug one, otherwise it kept overwriting it with the original.

Thank you for your work! Pozdro

I saw this too on Android 12 and master at 1d395af. To get past it I had to make this hack.

What is supposed to create this directory, if you don't do it with an adb shell command? You use one to remove it again.
