androidx.room.RoomOpenHelper.e (RoomOpenHelper.java:15)

Question

I'm getting this error in Crashlytics (Firebase). The app is built in Flutter and I'm not sure about this error that I don't get locally:

Fatal Exception: java.lang.IllegalAccessError
Illegal class access: 'androidx.room.v' attempting to access 'androidx.work.impl.v' (declaration of 'androidx.room.v' appears in base.apk)

apparently, plenty of devices are getting this issue everyday in Android 11 and it happens when the user logs in (I know that because of Crashlytics)

Answer 1

For me, I'm suspected about one package that uses sqlite, cached_network_image-> flutter_cache_manager->sqflite, because I have this too. If I'm wrong, it must be android play store related problem because user catches this crash just after update, even before dart main function, in which I cleaned all app directories and cache data by code, and it wasn't usefull.

Yes most of users can use app after clean app data or reinstall app! But it's bad experience for user.

I have opened issue about it in github flutter repo: https://github.com/flutter/flutter/issues/100821

And found some interesting closed similar issue, in which author of issue answered has found problem, I have thought he can help us and asked for some help, right now no answer: https://github.com/adjust/flutter_sdk/issues/73

For caching image I think it's better to use some kind of nosql db but I have not found any package for image cache with nosql db yet. In the future it will be great to this kind of package.

I think I have found solution for this problem, I was getting same type crashes in plenty amount of devices everyday. For me it is about java version and gradle version. First I have tired to update gradle version to latest but java version was not enough to support latest version of gradle, and I was using default android studio java before, I think it was 1.8 version maybe and I installed latest version of java. And configured project to compile with new version of java. After that I rolled out several tests in play console. Till today app doesn't have mentioned crash.
