[Bug] App crashing at homepage

Jammmmm commented 7 months ago

Description Just installed Neo Backup. I went through the initial steps and granted all required permissions. When it gets to the homepage, it crashes immediately.

My device is rooted and OAndBackup used to work fine.

Is there a way for me to determine why it's crashing?

I have tried:

Restarting the phone
Uninstalling/Reinstalling Neo Backup
Clearing the data and cache for the app
Turning off power saving on phone
Installing https://github.com/TacoTheDank/Scoop to catch the crash, but it isn't able to.

Steps To Reproduce

Launch Neo Backup
Crash

Expected behavior Not crashing.

Screenshots GIF of the crashing. The GIF loops but you get the idea. I launch Neo Backup and it crashes back to the desktop. neobackupcrash -

System Information(please complete the following information):

Device: LG v40 ThinQ
Android Version: 9 (Security Patch Level: January 1, 2020)
ROM: Stock, but device is rooted with Magisk and runs XPrivacyLUA (Neo Backup is given full permissions)
App's Version: 8.3.4

machiav3lli commented 7 months ago

Do you have patcher or such apps?

Jammmmm commented 7 months ago

No, Nothing at all.

machiav3lli commented 7 months ago

Having xposed/privacy results having an enormous amount of scenarios which may cause such crash. Any hidden apps? By "given full permissions" you mean there's no fake data feed? What xposed modules you have? What other root-level apps? …

Jammmmm commented 7 months ago

No hidden apps at all.

Correct, full permissions means there's no fake data feed. XPrivacyLua is not blocking anything at all to Neo Backup.

Xposed modules are EdXposed Manager, Scoop (which I installed after to debug Neo Backup) and XPrivacyLua.

Magisk modules are Always Trust User Certificates, Axet's Call Recorder, Riru (Riru - Core), Riru - EdXposed, SDCard R/W.

Apps that have root/superuser AdAway, Amaze, Aurora Store, DroidWall, EdXposed Manager, MatLog, Neo Backup, PCAPDroid, Scoop, Shell, Terminal Emulator, VPN Hotspot.

I'm personally not seeing anything out of the ordinary that should interfere with Neo Backup when it's scanning on the homepage.

Jammmmm commented 7 months ago

This might help. The crashing started in 8.3.0. Every version up to 8.2.5 works fine.

machiav3lli commented 7 months ago

Actually I think many of those could be the issue in one way or another. But let's follow the 8.2.5→8.3.0 thingy for this issue: To get a full log (with some noise), install LogFox, use a filter using NB's package name and then check the logcat on running NB, there should be an indicator. One guess would be Compose, having some issues on the rusty A9, another one is still, one of the modules & root-apps having some funny non-standard "qualities".

I also tried disabling all Xposed and Magisk modules and rebooting. I also removed superuser/root access for everything except for Neo Backup. It still crashes.

I'm not sure what to look for in the dump. I see a null pointer dereference and "libc : Access denied finding property "ro.vendor.lge.hwbinder.vm.size"" but other than those, nothing really stands out to me personally.

whitedavidp commented 3 months ago

FYI I am seeing exactly the same behavior on my LG V40 with stock, but rooted with Magisk, and having LsPosed installed, Android 9 immediately after installing the 8.3.6 version. I have no logs or other information except to say it looks exactly like the animated gif above. Had to go back to last night's TWRP backup in order to recover without having to uninstall and re-install the previous version I was using (8.2.5).

Jammmmm commented 3 months ago

Interesting! Your setup is basically the same as mine. I wonder if it's an LG v40 issue, or an Android 9 issue. I'm leaning towards the latter because issue #827 also mentions crashing on Android 9 but on a different device (S905X3 TV box).

whitedavidp commented 3 months ago

It certainly could be. I have been just fine with 8.2.5 but when recently suggesting a feature for Neo and stating that I was on 8.2.5 I was questioned why I was not on 8.3.6? At the time, I had no good reason save that I was not aware of it (if it ain't broke, I don't often try to fix it). But now I do :-(

whitedavidp commented 3 months ago

To be clear, I was on 8.2.5 and tried to move directly to 8.3.6 of Neo. In another thread - but on this topic - the dev said "I never planned for such jumps (I can imagine that these crashes are either caused by backup properties or databases)". I see there are at least 5 releases between 8.2.5 and 8.3.6 so perhaps the "fix" is to install them one at a time in strict order?

machiav3lli commented 3 months ago

Ok, there's no external crash logs rather all is hsppening intern, or maybe the XPLUA is catching logs out of privavacy incentive?... If it's not a ROM issue, I can imagine that it's Magisk or Lsposed related (sans modules too). Can you please try removing lsposed fully, then try using scoop to catch the crash logs?

machiav3lli commented 3 months ago

@whitedavidp Jammmmm have alreadydone through testing and the issue starts at 8.3.0 already. I can't say more than this seems setup bound.

The provided logcat from @Jammmmm doesn't provide any clear pointers, but there's some hints at XPLUA

Thanks, I had not noticed that yet. This is good as I cannot seem to find how to get at older versions of the APK on Fdroid anyhow... I am likely just a dumb-ass :-)
