@shrastiRisor Thanks for reporting. armv7l is currently not a supported hardware architecture for Android. Can you share more details on the device your code is running on?

You can also find the supported architectures in the docs.

@greenrobot-team This crash has been reported on crashlytics. Following are the few devices:

1. Brand:Motorola, Model:Motorola One Vision, Version:Android 5.1
2. Brand:LGE, Model:Nexus 5X, Version:Android 6.0.1

@greenrobot-team Wouldn't Android pick the armv7(a) libs for this CPU?

[shrastiRisor]

@greenrobot-team seems like it is not doing so.

[greenrobot-team]

Looks like the CPUs of both devices support 64-bit and both devices were shipped with a 64-bit version of Android, so arm64-v8a. And yes, Android would fall back to choosing the armeabi-v7a variant of ObjectBox if the arm64-v8a one were not available for some reason. https://developer.android.com/ndk/guides/abis

@shrastiRisor Does your project have any ABI filters configured that might exclude arm64-v8a or armeabi-v7a? https://developer.android.com/studio/projects/gradle-external-native-builds#specify-abi

[greenrobot]

@greenrobot-team Android 21+ offers some nice extra info that could be helpful to devs and us: https://developer.android.com/reference/android/os/Build#SUPPORTED_64_BIT_ABIS - If available, add that to the "please report this to us" string?

[shrastiRisor]

@greenrobot-team No, we have not configured any ABI filters

[shrastiRisor]

@greenrobot-team Do you guys need any other information for this?

[greenrobot-team]

@shrastiRisor If you have the time, provide the value of https://developer.android.com/reference/android/os/Build#SUPPORTED_ABIS from the affected devices (and maybe the 64-bit one mentioned above).

We'll also try to add that to the library in the next update. We need to understand why Android is not loading one of the provided libraries (ObjectBox ships with Android libraries for armeabi-v7a, arm64-v8a, x86 and x86_64).

[greenrobot-team]

Also something more easily checkable: Open your APK or AAB in Android Studio and have a look at the lib folder to see which ABIs are actually included. As said above, there should be a folder for armeabi-v7a, arm64-v8a, x86 and x86_64.

You may also try using ReLinker as described in https://docs.objectbox.io/android/app-bundle-and-split-apk#buggy-devices-api-22-or-lower considering at least one affected device is below API 23 (Android 6.0).
