public interface CapabilityApi

This interface is deprecated.
Use CapabilityClient.

Exposes an API to learn about capabilities provided by nodes on the Wear network.

Capabilities are local to an application.

Constant Summary

String	ACTION_CAPABILITY_CHANGED	Capability changed action for use in manifest-based listener filters.
int	FILTER_ALL	Filter type for getCapability(GoogleApiClient, String, int), getAllCapabilities(GoogleApiClient, int): If this filter is set then the full set of nodes that declare the given capability will be included in the capability's CapabilityInfo.
int	FILTER_LITERAL	Filter type for addListener(GoogleApiClient, CapabilityListener, Uri, int): if this filter is set, the given URI will be taken as a literal path, and the operation will apply to the matching capability only.
int	FILTER_PREFIX	Filter type for addListener(GoogleApiClient, CapabilityListener, Uri, int): if this filter is set, the given URI will be taken as a path prefix, and the operation will apply to all matching capabilities.
int	FILTER_REACHABLE	Filter type for getCapability(GoogleApiClient, String, int), getAllCapabilities(GoogleApiClient, int): If this filter is set then only reachable nodes that declare the given capability will be included in the capability's CapabilityInfo.

Constants

public static final String ACTION_CAPABILITY_CHANGED

Capability changed action for use in manifest-based listener filters.

Capability events do not support filtering by host, but can be filtered by path.

Public Methods

public abstract PendingResult<Status> addCapabilityListener (GoogleApiClient client, CapabilityApi.CapabilityListener listener, String capability)

Registers a listener to be notified of a specific capability being added to or removed from the Wear network. Calls to this method should be balanced with removeCapabilityListener(GoogleApiClient, CapabilityApi.CapabilityListener, String) to avoid leaking resources.

Listener events will be called on the main thread, or the handler specified on client when it was built (using GoogleApiClient.Builder.setHandler(Handler)).

Callers wishing to be notified of events in the background should use WearableListenerService.

public abstract PendingResult<Status> addListener (GoogleApiClient client, CapabilityApi.CapabilityListener listener, Uri uri, int filterType)

Registers a listener to be notified of capabilities being added to or removed from the Wear network. Calls to this method should be balanced with removeListener(GoogleApiClient, CapabilityApi.CapabilityListener) to avoid leaking resources.

uri and filterType can be used to filter the capability changes sent to the listener. For example, if uri and filterType create a prefix filter, then only capabilities matching that prefix will be notified. The uri follows the rules of the <data> element of <intent-filter>. The path is ignored if a URI host is not specified. To match capabilities by name or name prefix, the host must be *. For example:

wear://*/<capability_name>

Listener events will be called on the main thread, or the handler specified on client when it was built (using GoogleApiClient.Builder.setHandler(Handler)).

Callers wishing to be notified of events in the background should use WearableListenerService.

public abstract PendingResult<CapabilityApi.AddLocalCapabilityResult> addLocalCapability (GoogleApiClient client, String capability)

Announces that a capability has become available on the local node.

public abstract PendingResult<CapabilityApi.GetAllCapabilitiesResult> getAllCapabilities (GoogleApiClient client, int nodeFilter)

Returns information about all capabilities, including the nodes that declare those capabilities. The filter parameter controls whether all nodes are returned, FILTER_ALL, or only those that are currently reachable by this node, FILTER_REACHABLE.

The local node will never be returned in the set of nodes.

public abstract PendingResult<CapabilityApi.GetCapabilityResult> getCapability (GoogleApiClient client, String capability, int nodeFilter)

Returns information about a capability, including the nodes that declare that capability. The filter parameter controls whether all nodes are returned, FILTER_ALL, or only those that are currently reachable by this node, FILTER_REACHABLE.

The local node will never be returned in the set of nodes.

public abstract PendingResult<Status> removeCapabilityListener (GoogleApiClient client, CapabilityApi.CapabilityListener listener, String capability)

Removes a listener which was previously added through addCapabilityListener(GoogleApiClient, CapabilityApi.CapabilityListener, String). The listener is only removed from listening for the capability provided and will continue to receive messages for any other capabilities it was previously registered for that have not also been removed.

public abstract PendingResult<Status> removeListener (GoogleApiClient client, CapabilityApi.CapabilityListener listener)

Removes a listener which was previously added through addListener(GoogleApiClient, CapabilityApi.CapabilityListener, Uri, int). The listener is only removed from listening for the capability provided and will continue to receive messages for any other capabilities it was previously registered for that have not also been removed.

public abstract PendingResult<CapabilityApi.RemoveLocalCapabilityResult> removeLocalCapability (GoogleApiClient client, String capability)

Announces that a capability is no longer available on the local node. Note: this will not remove any capabilities announced in the Manifest for an app.
