OTP list empty on Android O

@alphazo Could you upload a logcat? This could be the same error as #16

I'm gonna set up an Android O virtual phone tomorrow and check it out myself.

More progress (Nexus5X).

• TitaniumBackup Restore (App+Data) : Empty list
• TitaniumBackup Restore (App+Data) + andOTP JSON restore : Empty list
• All the above then data erase + andOTP JSON restore : list is back ;)
• andOTP uninstalled then re-installed + TitaniumBakup restore (data only): Empty list
• andOTP uninstalled then re-installed + andOTP JSON restore : list is back ;)

There is a crypto related exception in the logcat: logcat_and_device_info.zip

PS: andOTP is not the only app I had issue with. Waze for expample kept FC until I fully erased app data.

Yes, this is to be expected. See the "Backups" section of the README on GitHub.
Titanium Backup only saves the encrypted data files, but to decrypt them a key is needed which is stored in the Android KeyStore. This key can not be backed up, so you can only use the internal backup function and not Titanium.

I think I read somewhere that Waze also uses the KeyStore, so it's probably the same problem there.

Good to hear there is an explanation. At least I had a recent in-application backup handy ;)

After looking at your logcat I'm 99% sure that is exactly whats happening.
I will close this report, just open a new one if there is something else strange happening on Android O.
