Dont work on Huawei
I believe Google Services are required by the SDK.
full log:
The issue is that it did work in the debug version. The version hosted a few days ago (which is currently unavailable via the link) was itself still an unstable build. Google Services are installed on top of Huawei's OS. Previously, everything worked correctly with the old version; with the debug version it wasn't great but it did launch, whereas with the final version, it stopped launching altogether.
Can you collect full Android logs for the app?
Unfortunately, apart from the screenshot above, the application does not provide any other logs. A couple of notes, no details at all. And when launching the application, there is a license error in the interface. What kind of behavior am I getting: When you turn on the app, the switch is not turned on forcibly, it remains on the meta, no permissions (location, activity) solve the problem. The logs do not write anything except the screenshot above. Debug version 9.0.0 worked (size 98 MB). And now everything is activated in it, but it is inoperable. I'm still using version 7.9.
It looks like Huawei requires a separate license:
I recommend creating a feature request on GitHub and we'll see how much interest we will get.
New client cannot start background monitoring on Huawei P60 Android smartphone. The earlier test version hosted at https://traccar.nyc3.digitaloceanspaces.com/download/app-debug.apk was functional. However, all final versions 9+ fail to initiate monitoring. Logs are not pushed, and the monitoring service simply does not start. There are no issues with other Android devices that have Google Services. It's more complicated with Huawei due to their own services, but the debug version did work.
