CapabilityClient

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

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

Filter type for getCapability(String, int), getAllCapabilities(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.

Filter type for addListener(OnCapabilityChangedListener, 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.

Filter type for addListener(OnCapabilityChangedListener, 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.

Filter type for getCapability(String, int), getAllCapabilities(int): If this filter is set then only reachable nodes that declare the given capability will be included in the capability's CapabilityInfo.

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 removeListener(OnCapabilityChangedListener, String) to avoid leaking resources.

Listeners will be called on the main thread, or the looper set in Wearable.WearableOptions.

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

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 *. i.e.:

wear://*/<capability_name>

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

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.

Removes a listener which was previously added through addListener(OnCapabilityChangedListener, Uri, int). The listener will continue to receive events for capabilities it was previously registered for with addListener(OnCapabilityChangedListener, String), until those instances are removed.

Removes a listener which was previously added through addListener(OnCapabilityChangedListener, String). The listener is only removed from listening for the capability provided. All other instances of this listener will continue to receive events until they are also removed.

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.
