In others devices the library works fine.

Can you help me?

[fermedina]

Hi! I have the same problems in all Huawei devices. What is the problem?

[iamMehedi]

So the library is not working at all on those devices? Or does this happen after you've changed PIN/Password/Fingerprint of the device? And please share the OS version and the type of screen security you had in place.

[Gaetano-Dati]

Hi, same problem here.. Android O is the OS and the device is a Nexus6 Emulator. Trying to put a jsonString from GSon library. GSon.toJson(string)

[iamMehedi]

@Gaetano-Dati thanks for the info. I'll see if I can reproduce it and find out the reason behind it.

[Gaetano-Dati]

So did you come out and find the solution?
Thanks

[iamMehedi]

@Gaetano-Dati Tried the sample app on A Nexus 6 emulator with Android O (with google APIs) but couldn't reproduce the issue.

[Gaetano-Dati]

The issue was reproduced on a physical device during a robo test by firebase. The error is at the moment the Application class gets called. I didn't experience this error on one of my devices but I don't have a Huawei. I emulated the Application on a Nexus 6 with Android O and It didn't give me the error. Have you got a Huawei physical devices in order to test it?

[Gaetano-Dati]

I'm talking about this issue:
KeyStoreService.del null object reference on HUAWEI device 7.0 #25

I pasted this because we are in another thread. I found a solution to my first issue which is at the starting point of this list.

[iamMehedi]

@Gaetano-Dati No, unfortunately don't have a Huawei device for testing.
