Hello! 👋 Thanks for logging this issue. Please remember we are all volunteers here, so some patience may be required before we can get to the issue. Also remember that the fastest way to get resolution on an issue is to propose a change directly, https://github.com/ankidroid/Anki-Android/wiki/Contributing

Hi there!
Why would you use 2.14alpha18? We are on 2.15alpha now
Also, you do not include the crash UUID so we can't trace this
we can reopen if you reproduce this with the latest alpha and you include the UUID with crash reporting enabled so we can locate the stack trace to fix it

[Sunt-ing]

I pulled the latest updates from the master branch just now, and find the problem is still here.
Also, as you advised, I have shown all the debug info.

Please tell me what I still need to add if there is.

Strange - I'm unable to see any crash reports for that user id

I think with from-source-code and alpha builds you may need to go into settings -> advanced and turn on crash reporting for it to send them - can you try that? then I can search for this ACRA UUID again and try to get the crash report

We turn off crash reports by default on source code builds because we expect crashes during development and don't want to send reports for them normally. You have to enable it every time the app restarts

1. After pulled the master branch I tried reproducing it but failed. However, when I taped "Manage note types", it crashed again. This works both on my cell phone and my emulator. And I reported it.
2. All the debug info has been updated.
   AnkiDroid Version = 2.15alpha17

Android Version = 9

ACRA UUID = 741efefa-e3a5-4eef-a2e8-e5032cead758

Scheduler = std

Crash Reports Enabled = true

I continue to have no crash reports for this device. I must see the crash trace in order to debug it.
You are running an emulator, so you may capture (and paste in here) the crash reports yourself, that would be an incredible help.

If you could follow adb logcat while creating the crash and paste the trace we can probably fix it almost immediately

[mikehardy]

Please use triple-backticks to enclose text like that, it really helps :-). But! Thank you for the stack trace that helps

Do you have a collection.apkg you could export (and change filename to .zip for upload here) that you could share so we could reproduce?

[Sunt-ing]

collection-20201221222207.zip

[Arthur-Milchior]

I can reproduce. I'll take a look at it

[mikehardy]

@Sunt-ing your help was vital in finding and fixing this issue thank you! I will have a new alpha out shortly with the fix, but it is already merged into the main branch
