Network State¶
NetStateUtils provides a series of methods to get the network state. They are divided into isXXX and hasXXX, where isXXX is used to determine the status of the current active default data network and hasXXX is used to determine the status of all existing network connections.
NetworkInfo and NetworkCapabilities
For versions below API 29, NetworkInfo will be obtained to check whether the network is available. For API 29 and above version, NetworkCapabilities will be obtained to check whether the network is available.
