[BUG]: Random mistaken "Failed to load xxx.bin" toast messages when using JS API

[silidev]

Checked for duplicates?

• [X] This issue is not a duplicate

Does it also happen in the desktop version?

• [X] This bug does not occur in the latest version of Anki

What are the steps to reproduce this bug?

Use the JS API a lot. It only happens randomly. Maybe it is possible to reproduce it reliably by calling some harmless API method in a loop.

Expected behaviour

No error message should be displayed.

Actual behaviour

Sometimes (no discernible pattern) AnkiDroid will throw a "Card Content Error: Failed to load 'xxx.bin'" warning, despite everything working fine. xxx being a name referring to an element of the JS API, e.g . "cardDue.bin", "cardMod.bin", "ttsSetLanguage". Maybe all strings from the jsApiList in AnkiDroid/src/main/assets/scripts/js-api.js are possible.

Debug info

AnkiDroid Version = 2.18.0 (464cf290cc77c3f2c562cb03b408b78a13be261b)

Backend Version = 0.1.38-anki24.04.1 (24.04.1 ccd9ca1a8309b80bcb50ddc5d99c7ce63440bce9)

ACRA UUID = 4d6cad38-e805-4913-82fe-99652a272d86

FSRS Enabled = true

Crash Reports Enabled = true

(Optional) Anything else you want to share?

I am pretty sure this began with JS-API 0.2 or 0.3.

This is the string: Card Content Error: Failed to load ‘%s’

@silidev Could you provide a sample deck?

Yes, I will build one and put it here. Thanks for looking into this. 🙂

Hi David! Unfortunately, I cannot reproduce it in my sample deck. My production collection is not suitable for testing by others. I hope I find time to build my own AnkiDroid from source. Then I will try to fix it myself and test it in my production collection. I guess you best close this issue for now. Thanks again for having a look at this.

[david-allison]

I can get a slight reproduction with a CACHE_MISS error with showAnswer when attaching Chrome Dev tools

Let's leave this open, I know where it needs to be fixed, but I don't know why

@silidev Can you use logcat? I could add some diagnostic logs instead, which can be used to resolve this

[silidev]

@david-allison I never used logcat, but I have used the adb command line before and guess that it won't be that difficult, will it?

[silidev]

@david-allison By the way: Kind of the deeper reason, why this is a problem at all, is this: the toast message with the error is very low on the screen, hiding the answer buttons. If it would be positioned higher on the screen everything would be just fine.

Other toast messages are also a somewhat annoying, like "1 card rescheduled". In the current position the toast message is hiding the answer buttons. If it would be a little bit higher, higher than the answer buttons, it would be no problem it all. I understand that you are interested what is causing the error, but repositioning the toast message display to a higher Y-position would improve the user experience for all types of toast messages.
