Interface ConnectivityService

All Known Implementing Classes:
AndroidConnectivityService, DummyConnectivityService, IOSConnectivityService
public interface ConnectivityService
The connectivity service can be used to determine whether the device is currently connected to a network or not. The connectivity can be to any networking service, i.e. WiFi, cell phone data, etc.

The ConnectivityService provides a read-only connected property that is updated whenever the network connectivity of the device changes. A user of the ConnectivityService can listen to changes of the network connectivity, by registering a ChangeListener to the connected property.

Example

 ConnectivityService.create().ifPresent(service -> {
      boolean connected = service.isConnected();
      System.out.println("Network connectivity available? " + String.valueOf(connected));
  });
