@iamMehedi please can you tell me something about It? Thanks

[iamMehedi]

Huawei devices are encountering a few issues and most probably that has to do something with the device's keystore implementation. I'll take a closer look at this tomorrow and let you know if I can find anything.

Ok, the client is waiting for my Application which also contains your library.
Thank you very much.

[iamMehedi]

@Gaetano-Dati the error is happening in internal code of the KeyGenerator

[Gaetano-Dati]

And how can I delete this error? Modify something into the KeyGenerator class?
Can you do it and publish new version?
I'm about to publish the application.
Thanks

[iamMehedi]

It's an internal issue of android/huawei's Keystore implementation, so there's nothing to fix in the library in particular.

[Gaetano-Dati]

Uhmm so the crash remains? And we can't deal with it? Ok. Thanks

[Gaetano-Dati]

I'm afraid that this problem will happen on every Huawei device.

[iamMehedi]

As the issue seems to be with the OS on Huawei devices, this will happen on all their devices at least the ones that are running the same version of the OS.

Hello,

I have the same issue in my Huawei P8 Lite.

@Gaetano-Dati @iamMehedi
Were you able to solve this? Workaround?

[Gaetano-Dati]

No, sorry. I'm still waiting for a solution Il gio 31 mag 2018, 17:40 Javi Chaqués <notifications@github.com> ha scritto:

:(
How are you save the preference ins this moment? @Gaetano-Dati

Thank you

[maxkomarychev]

@Gaetano-Dati hey, did you get this error on actual device you have or it's from google pre-launch report or any other crash-reporting service (like crashlytics..)?

if first is true - did you by any chance tried this on any other android version on Huawei device?

[kutran]

I just saw this on our pre-launch report trying to start an internal test track. I am wondering running this will cause the same problem on Huawei (or any other phones like ZTE).

I think FireBase has Android Testing on the cloud; I am going to try it out.

I tried last version 0.7.0 on my Huawei P7 works well now.
