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.

    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
