Android wear: geofence - ApiException: 1000

As you read the documentation and see that the error code is corresponding to GEOFENCE_NOT_AVAILABLE, plus according to @Mr.Rebot comment :

"Not all wear devices have the hardware to support this [...]"

You may assume that GEOFENCE IS NOT AVAILABLE on your Huawei watch 2 device.

You may also ask to Huawei support directly to have confirmation.
