NodeClient

  • NodeClient exposes an API for learning about local or connected Nodes, with node events delivered to all applications on a device.

  • New code should use CapabilityClient for creating and listening to application-specific network events instead of NodeClient.

  • NodeClient provides methods to get information about connected nodes, the local node, and the companion package or node ID for a given node.

  • NodeClient includes a constant for the node migration action and a listener interface for node migration events.
public abstract class NodeClient extends GoogleApi<Wearable.WearableOptions>

Exposes an API for learning about local or connected Nodes.

Node events are delivered to all applications on a device.

New code should use CapabilityClient which allows you to create and listen to application-specific network events.

Nested Class Summary

interface NodeClient.OnNodeMigratedListener Receives events after a node migration has successfully finished.

Constant Summary

String ACTION_NODE_MIGRATED Node migration action for use in manifest-based listener filters.

Constant Value: "com.google.android.gms.wearable.NODE_MIGRATED"

Public Methods

public abstract Task<String> getCompanionPackageForNode (String watchNodeId)

Gets the package name for the Companion application associated with this node.

Parameters
watchNodeId must be a valid nodeId corresponding to a connected watch
Returns
  • a Companion application package name; returns an empty string instead if none are associated, or if the specified watch is not currently connected

public abstract Task<List<Node>> getConnectedNodes ()

Gets a list of nodes to which this device is currently connected, either directly or indirectly via a directly connected node.

The returned list will not include the local node .

public abstract Task<Node> getLocalNode ()

Gets the Node that refers to this device. The information in the returned Node can be passed to other devices using MessageClient , for example.

public abstract Task<String> getNodeId (String bluetoothAddress)

Gets the node ID associated with a bluetooth address.

Parameters
bluetoothAddress must be a valid bluetooth address corresponding to a paired watch
Returns
  • the nodeId associated with the device
