Hi @mohamadbadr

Can you tell me if you are running the SDK on a simulator, or a physical device?
Is the behavior occurring on multiple devices?

[mohamadbadr]

Hi @mparadina

its a production issue that is occurring with the users on multiple devices and all android os versions

[mparadina]

Hi @mohamadbadr

Thank you for the swift response.

Are you able to share on which devices, along with Android OS versions, the crashes are occurring?

[mohamadbadr]

Hi @mparadina,

Here is a small sample:

Brand	Model	Android OS version
Samsung	Galaxy S22	11
Google	Pixel 5	13
Oneplus	OnePlus 10 Pro 5G	9
Xiaomi	Mi 10 Pro	12
Huawei	MED-LX9	10

The issue is happening with 63 Users and occurred 666 times in the last 7 days. We think it started when we migrated to Android SDK 34

@mparadina
any updates?

Hi @mohamadbadr

I've checked with the team internally, and they've asked if you know are the reported devices, by any chance, rooted?
This shouldn’t happen on non-rooted devices if the SDK .so file is present in the APK.

Could maybe double-check if the libBlinkID.so is in your APK or App bundle?
It should be located inside lib/<architecture> folders when you extract the App bundle.

[mohamadbadr]

Hi @mparadina
I have checked the APK and the libBlinkID.so exits forarm64-v8a and arm64-v7a architectures, but it doesn't exist for x86 and x86_64 architectures.

And is it a requirement to use the SDK for the app not to be rooted, I think we would have captured this issue earlier if that was the case.

[mparadina]

Hi @mohamadbadr

Thank you for the feedback.
If you are using other native libraries in your application, the issue could be with architectures that we do not support.
The BlinkID SDK has support for the 'armeabi-v7a' and 'arm64-v8a' architectures. More info is explained here.

If the application is launched on a device with a different architecture that we do not support, the crash will happen.
To ensure that only ARMv7 and ARM64 are used, you will need to set the abiFilters and keep only 'armeabi-v7a' and 'arm64-v8a'. More info here:

android {
    ...
    ndk {
        // Tells Gradle to package the following ABIs into your application
        abiFilters 'armeabi-v7a', 'arm64-v8a'
    }
}

Hi @mohamadbadr

Just wanted to follow-up here.
Did the answer above help?
