If you need more information you can ask. And yes my firebase auth is enabled as well as storage and realtime database
回答1:
I had the same problem on my Huawei device (a P9 Lite with android 7.0), to solve this issue just remove the currently installed version of Google Play Services restoring it to the default one that shipped with our device (this can be done via the settings app). Then reboot your device, and update the Google Play Services application to the latest version. Then run your application and it should work.

I face the same problem with on my Huawei device (a P9 Lite with android 7.0), i have solved this by Clear Cache inside the Settings-->Apps-->Google Play Services-->Storage
I hope this will help you. Cheers..!
回答3:
I had the same problem on my Honor STF-L09. I resolved the issue by updating the google play services to the beta version, as there are known problems with the current version on huawei and honor devices.
See below for instructions: https://www.androidauthority.com/google-play-services-huawei-honor-866884/
It gives a bit more insight, but basically it contains a link to sign up for the google play services beta:
