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

iamMehedi commented 6 years ago

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 commented 6 years ago

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

Gaetano-Dati commented 6 years ago

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 commented 6 years ago

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

Gaetano-Dati commented 6 years ago

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

Gaetano-Dati commented 6 years ago

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

iamMehedi commented 6 years ago

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 commented 6 years ago

No, sorry. I'm still waiting for a solution

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

Thank you

maxkomarychev commented 6 years ago

@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 commented 6 years ago

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.

xrom888 commented 6 years ago

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