AnkiDroid 2.23.1 crashes on importing large apkg deck

AnkiDroid (Android) Help
1

I have AnkiDroid 2.23.1 installed on two phones - one old phone running stock Android 10 (which is offline most of the time) and another phone running GrapheneOS Android 16.

I have a deck package which is 155MB in size. I imported that deck on the old Android 10 phone with no problems, and it works just fine.

But when I try to import the same deck on the Android 16 phone, the app immediately crashes.

If I restart the app, it’s the same as it was before the crash - no decks, and I can repeat the import, but it always crashes.

I tried clearing the cache but that makes no difference. I’ve also tried uninstalling and reinstalling the app.

The strange thing is, although the import apparently fails, the app cache size increases from 0 bytes to 155MB, the exact same size as the deck I’m trying to import.

AnkiDroid log extract - failed deck import

Apologies for the unformatted log text. I tried to follow the formatting tips but it seems I got it wrong.

[I edited your post to un-comment-out the backticks. See if that’s what you were going for. ]

If you already imported it, you shouldn’t need to import it again. It should be synced in your AnkiWeb account, and will download to your new device when you set up syncing. [This doesn’t directly solve the issue, but it will get you past it for now.]

4

Ok then, I’ll setup an Anki account and see if the sync method you suggest will solve the issue for now.

Would be nice if someone in your dev team could look into an actual fix for the crash though, but I understand there may well be higher priority issues that they are busy dealing with right now.

Thanks for re-formatting my post. Much neater!

I just thought, maybe I’ve already got an Anki account. What I mean is, when I created an account for this forum I thought it was just for the forum but perhaps it’s the same credentials for synching. I’ll have to check.

They see all reports and will let you know if they need more information.

Whether you used the same login credentials or not, it’s not the same account. Your account for posting here is part of this Discourse forum. Your account for syncing would be an AnkiWeb account – Syncing with AnkiWeb - Anki Manual .

Hi, could you copy Settings - About - Copy debug info.

If you’re running the full build (F-Droid/GitHub), could you check for filesystem permission corruption by temporarily opening our play build: https://github.com/ankidroid/Anki-Android/releases/download/v2.23.1/dev-AnkiDroid-2.23.1-play-universal.apk. If it doesn’t show a fatal error, it’s fine to uninstall.

Ok thanks.

First, I was running the arm64-v8a build which I obtained from GitHub. Oddly, in the debug info, it appeared as “ProductFlavor = play”.

So I uninstalled that build and installed the ‘full-universal’ build. On running this build for the first time, the app requested ‘All files access’ which I granted. This request did not appear with the arm64-v8a build, and in that build, Settings > Advanced showed AnkiDroid directory to be a deeply buried one (the actual app directory, I suppose).

With the ‘full-universal’ build, the AnkiDroid directory is < storage/emulated/0/AnkiDroid > which is easily accessible in my file manager.

I also went to App Info > Permissions and granted All Notifications permission (although that permission had not yet been requested by the app).

Unfortunately, the full-universal build also crashed when importing the deck package.

Finally I tried the ‘play-universal’ build. It did not show a fatal error, but it crashed on deck import the same as the other builds.

I’ve reinstalled the full-universal build for now.

One other thing - this being GrapheneOS, there are some extra settings available in App Info that you don’t get with stock, one of them being “Exploit protection compatibility mode”, which was disabled by default with all builds - but I did try enabling it, again with all builds, just to see if that changed anything in the app’s behaviour, but it didn’t.

Finally, here’s the debug info from the full-universal build.

AnkiDroid Version = 2.23.1 (3f3133b496b531383e9a6494f5a7704634935308)

By the way, I use many apps downloaded from GitHub, and I always download the arm64-v8a build, rather than the universal (when there there is a choice). I’ve always figured, why download an apk that’s got two, or even four builds in it (arm64-v8a, armeabi-v7a, x86, x86_64) when all I need is arm64-v8a - and I’ve never had any problems before. But as noted above, the AnkiDroid arm64-v8a build does not ask for all files access and the AnkiDroid directory is inaccessible to a standard user. So to get that ‘feature’ you have to download 102MB of data rather than 32MB.

No reports in our crash report database.

Could you go to Help - Get help - Send troubleshooting report

Or provide the stack trace (as you seem to have logcat setup).

Filesystem permission corruption only blocks installs where we can’t request MANAGE_EXTERNAL_STORAGE, (Play Store only), and the Play Store has their own mechanism to handle compression of the app

Thought you might like to know I just installed <AnkiDroid-2.23.2-full-universal.apk> from GitHub (clean install) and was able to import the 155MB deck with no problems. It’s all working good.
