dlt.onNetworkStatusChange

Introduction

Listen for network status change events.

Note:
Currently, only accurate changes between Wi-Fi, cellular data, and no network are supported.
There is a possibility that changes from 2G to 4G and other cellular data network states may not be detected. It is recommended that developers do not rely too much on this feature of detecting changes in cellular data network types.
