[Bug] App looses access to backup folders, thus finds no backups
Opened this issue · 1 comments
Description
After configuring a backup folder and performing backups of some apps, at first everything seems ok: backups are listed and can be restored. However, after a while of device inactivity, the app cannot find any of the backups.
Steps To Reproduce
- Select a backup folder
- Backup one or two apps
- Backups are seen in the app list
- Close Neo Backup (even force close from settings)
- Open Neo Backup
- Backups are stil listed and restorable
- Close Neo Backup or switch to different app
- Leave the device alone for ~30 min
- Open Neo Backup
- All backups are missing (but clearly exist in the files system)
Expected behavior
Backups remain accessible in the app as long as they are not deleted by the user or the retention rule.
System Information(please complete the following information):
- Device: Lenovo Tab M11
- Android Version: 13
- ROM: Stock rooted with Magisk
- App's Version: 8.3.6
Additional Notes
Nothing I tried, fixed the issue:
- created the backup folder from within Neo Backup, in file manager app or in adb shell
- used internal storage, primary SDCard, secondary SDCard, USB stick
- switced allowShadowDefault and shadowRoot on and off
The behavior remains the same: after a while all backups disappear.
Additional info
I managed to assemble a working setup: external USB hub with an USB stick, of course this is not a solution.
Several other apps using content: URL to access files have similar problems on this device. Apparently it is kind of Lenovo's "feature", all "internal" FS handles (and their permissions) acquierd via Content Manager API get ivalidated after a period of inactivity and have to be requested again. Apps using file: URL or native OS API are not affected.
