In others devices the library works fine.

Can you help me?

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

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.

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)

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

So did you come out and find the solution? Thanks

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

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?

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.

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