[zhouyiself]

libbarhopper_v2.so is from an old version 16.2.0, can you try the latest SDK version 17.0.2 instead?

I am still facing this issue on 17.0.2 version.

[usewr]

facing the same crash, any way to prevent the lib from crashing , consumers are having bad experience.

[SilverDestiny]

Hi, this error means the native library wasn't loaded correctly.

Could you check the native library was there in your built APK, for the correct architecture, normally arm64? Did you configure anything like https://developers.google.com/ml-kit/tips/reduce-app-size#advanced_exclude_unused_ml_kit_binaries in your app?

[drunamana]

As far as I remember, there was no problem with the universal apk. The problem appeared when using the app bundle.

The configuration of abiFilters is present:

ndk {
abiFilters "arm64-v8a", "armeabi-v7a", "x86", "x86_64"
}

When building the app bundle under arm64-v8a, the library is present in the set by architecture. (1- App bundle content, 2- base-arm64_v8a.apk content)

[alexbusuioc]

same issue on 17.0.3. has anyone found a solution to this?

[drunamana]

Searching. Noticed this bug on universal apk as well, so the bug is reproduced by app bundle/universal apk

[vpmalley]

Got the same exception in versions 17.0.2, 17.0.3, 17.1.0.
I noticed that only devices with Android 13 are impacted. Not all users are, though.
Another thing is the app uses some dynamic features (but the barcode MLKit is in the main app module), I wondered if this could have an impact on the packaging part. I downloaded the APKs for one of the impacted devices and I couldn't see a difference between the APKs downloaded for this version and a previous one without dynamic features, so that's unlikely.

Another thing is the app uses some dynamic features (but the barcode MLKit is in the main app module), I wondered if this could have an impact on the packaging part.

I realised this was the cause of the issue. If the base app (which contains the barcode library) is installed and no other module is installed, it works fine. If a module is installed and the activity is restarted, it works fine. If a new module has just been installed in the current activity but the native libraries aren't reloaded and the activity isn't restarted, it causes this kind of crash. Hopefully that can give a hint to some of you.

Got the same exception with the version 17.2.0.
