NodeClient
Stay organized with collections
Save and categorize content based on your preferences.
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.

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
