Debug info
put everything I could up above - this is 2.21alpha5 though, release mode, most current we have
(Optional) Anything else you want to share?
No response
Research
- [x] I have checked the manual and the FAQ and could not find a solution to my issue
- [x] (Optional) I have confirmed the issue is not resolved in the latest alpha release (instructions)
@david-allison nope turns out it was @user1823 they apparently created a new note and when the app saved and went back to the card browser this report was sent.
Perhaps after note creation you need to update the data set as changed ?
they apparently created a new note
Not created a note, but edited it.
I don't remember the exact sequence of events. My fingers were moving fast and I might have performed some other minor actions after saving the note such as swiping up/down, pressing the hamburger menu on top left, etc.
I spent some time on the issue ,as following the stack trace we can see that is error is thrown at 6821 line number in RecyclerView which checks is offsetPosition is < 0 or offsetPosition >= number of intems in the concerned adapter , now there are two possiblities that maybe there is addition of items in the dataset without notifying the linked adapter about it , or there is something wrong with the offsetPosition , my suspicion strongly inclines toward the inconsistent data
The maintainers here often don't assign issue to people. You just need to mention in the issue that you are working on it & then create a PR.
@Scapesfear you say you understand the issue, but did you consistently reproduce the issue? Reproduction is much more useful than guessing via code inspection
@mikehardy i couldn't reproduce the error ,as user did not provided any reproducing steps and i couldn't figure out that , but investigation with the help of log cat and stack trace i think
if (result.resultCode != RESULT_CANCELED) { Timber.i("CardBrowser:: CardBrowser: Saving card...") saveEditedCard() }
this is where the data inconsistency is happening as in the logcat statements there are 01-07 22:34:11.565 I/AnkiDroid(19831): CardBrowser:: Completed searchCards() Successfully 01-07 22:34:19.962 I/AnkiDroid(19831): CardBrowser::onPause 01-07 22:34:20.107 I/AnkiDroid(19831): CardBrowser::onStop 01-07 22:34:20.108 I/AnkiDroid(19831): CardBrowser::onSaveInstanceState 01-07 22:34:26.876 I/AnkiDroid(19831): CardBrowser::onStart 01-07 22:34:26.881 I/AnkiDroid(19831): CardBrowser::onResume 01-07 22:34:32.450 I/AnkiDroid(19831): CardBrowser:: Completed searchCards() Successfully 01-07 22:34:35.672 I/AnkiDroid(19831): CardBrowser::onPause 01-07 22:34:35.807 I/AnkiDroid(19831): CardBrowser::onStop 01-07 22:34:35.809 I/AnkiDroid(19831): CardBrowser::onSaveInstanceState 01-07 22:34:41.646 I/AnkiDroid(19831): CardBrowser::onStart 01-07 22:34:41.653 I/AnkiDroid(19831): CardBrowser::onResume 01-07 22:34:46.320 I/AnkiDroid(19831): CardBrowser:: Completed searchCards() Successfully 01-07 22:34:48.298 I/AnkiDroid(19831): CardBrowser:: Completed searchCards() Successfully 01-07 22:34:53.013 I/AnkiDroid(19831): CardBrowser::onPause 01-07 22:34:53.121 I/AnkiDroid(19831): CardBrowser::onStop 01-07 22:34:53.124 I/AnkiDroid(19831): CardBrowser::onDestroy 01-07 22:39:34.599 I/AnkiDroid(19831): CardBrowser::onCreate 01-07 22:39:34.626 I/AnkiDroid(19831): CardBrowser::onStart 01-07 22:39:34.628 I/AnkiDroid(19831): CardBrowser::onResume 01-07 22:39:35.085 I/AnkiDroid(19831): CardBrowser:: Completed searchCards() Successfully 01-07 22:39:35.524 I/AnkiDroid(19831): CardBrowser::onPause 01-07 22:39:35.790 I/AnkiDroid(19831): CardBrowser::onStop 01-07 22:39:35.792 I/AnkiDroid(19831): CardBrowser::onSaveInstanceState 01-07 22:39:45.457 I/AnkiDroid(19831): CardBrowser:: Completed searchCards() Successfully 01-07 22:39:45.460 I/AnkiDroid(19831): CardBrowser::onStart 01-07 22:39:45.468 I/AnkiDroid(19831): CardBrowser:: CardBrowser: Saving card... 01-07 22:39:45.470 I/AnkiDroid(19831): CardBrowser::onResume 01-07 22:39:45.968 I/AnkiDroid(19831): CardBrowser:: Completed searchCards() Successfully 01-07 22:39:46.434 I/AnkiDroid(19831): CardBrowser::onPause 01-07 22:39:46.582 I/AnkiDroid(19831): CardBrowser::onStop 01-07 22:39:46.583 I/AnkiDroid(19831): CardBrowser::onSaveInstanceState 01-07 22:39:54.492 I/AnkiDroid(19831): CardBrowser::onStart 01-07 22:39:54.495 I/AnkiDroid(19831): CardBrowser:: CardBrowser: Saving card... 01-07 22:39:54.497 I/AnkiDroid(19831): CardBrowser::onResume
i can't decode the exact steps to reproduce , but this is the footsteps of user related to CardBrowser
The user was in card browser and edited a card by tapping on it They saved the card and got the error
Those were the steps provided by the user, and we have the logcat.
You infer from inspection of RecyclerView that:
offsetPosition is < 0 or offsetPosition >= number of items in the concerned adapter
What happens with different boundary conditions related to number of items in adapter and position of adapter? That is, what happens if there is only 1 item in the browser, or the browser has enough items it is scrollable when you try to reproduce? What happens in combination with item count if the item you are editing is at the top of the adapter or the bottom of the adapter?
What did you try ?
(the subtext I am implying quite strongly is that when you are dealing with a crash bug, you should have no confidence that you fixed it unless you reproduced it first. I have no confidence in it anyway)
I tried doing the reproducing steps that user did on my device with the 2.21alpha5 and also on 2.20 release but it was working as expected , there is no error showing for me

@Scapesfear I gave specific scenarios about various boundary things you could try. I then asked a specific question: what did you try? Your answer is vague. What exactly did you try, lists of steps, specific conditions etc.
i tried Opening the card browser Making a change to a card and saving it as you said user did, i haven't checked the boundary things.
i haven't checked the boundary things.
I'm a bit disappointed at that after spending time emphasizing how important reproduction was and giving you suggestions.
What happens with different boundary conditions related to number of items in adapter and position of adapter?

What happens in combination with item count if the item you are editing is at the top of the adapter or the bottom of the adapter?
Earlier, I wasn't able to fully grasp what you were asking regarding the boundary conditions related to the number of items in the adapter and the position of the items. However, after working on a different issue, I now understand the scenario you're describing. You're referring to cases such as when there is only one item in the browser, or when there are enough items to make the browser scrollable. Additionally, you're highlighting what happens when the item being edited is at the top or bottom of the adapter.
Sorry to disappoint you earlier.
I will do all the test for the conditions and tell you what are the results
Results : Case - 1 item in whole browser Result- Worked fine
Case-2 enough scrollable items (71 cards ) in browser top card edit Result-Worked fine
Case-3 enough scrollable items (71 cards ) in browser last card edit Result-Worked fine

Logcat should be sufficient to deep dive. I don't have anything more or solid steps, but I reproduced it accidentally
Not sure if it is useful for you to know but I got the same crash today also, just after editing a note.

Nothing will have changed, but cheers!
I'm turning my hand towards getting 2.21 out the door when I'm back (to keep in line with Anki 25.01)
This WILL be fixed before it's out
Based on the stack trace, position 7 is flagged as invalid, meaning no entry exists for it in the dataset. This suggests the user tried to access the 7th card in the browser, which was visible in the UI but not in the dataset.
Hypothesis: The dataset and the UI are out of sync. The card may have been removed or modified in the dataset but was still displayed in the CardBrowser due to an incomplete or delayed update to the adapter.
Possible reasons for this: Race condition: Multiple threads may have modified the dataset simultaneously, causing inconsistency. Adapter update failure: The adapter might have failed to successfully update the dataset, though no error was reported. Missed dataset update: The dataset might not have been updated somewhere, leaving stale data visible in the UI.
The issue's unpredictability strongly suggests a race condition. Despite multiple attempts, I could not reproduce it, while @david-allison and user1823 could. This inconsistency aligns with the nature of race conditions, as thread execution is inherently unpredictable, much like the behavior of this issue.
I haven't seen this since the below PR was merged. I would like to get regression cover, but I'd like to confirm whether it's solved
- https://github.com/ankidroid/Anki-Android/pull/17781
Briefly looking at the code, BrowserMultiColumnAdapter is using BrowserRowCollection for the list of items that it shows, and that class is mutable. By making that list immutable we can rule out a huge chunk of issues related to the recycler view's assumption that the dataset must only change immediately before it is notified of changes.
I just scanned ACRA and there no reports of this since alpha6, however, there were not many reports to begin with - literally only 2, both @user1823
So I have no confidence the issue is fixed as sample sizes are too low to infer anything given we couldn't reproduce on demand or anything
I'd leave this open and deprioritize, given OK's suggestion.
We stopped most of the mutation of the list in https://github.com/ankidroid/Anki-Android/pull/17781, we should make it immutable.
I got two crashes today.
