DeviceService com.connectsdk.service.DeviceService

Overview

From a high-level perspective, DeviceService completely abstracts the functionality of a particular service/protocol (webOS TV, Netcast TV, Chromecast, Roku, DIAL, etc).

In Depth

DeviceService is an abstract class that is meant to be extended. You shouldn't ever use DeviceService directly, unless extending it to provide support for an additional service/protocol.

Immediately after discovery of a DeviceService, DiscoveryManager will set the DeviceService's Listener to the ConnectableDevice that owns the DeviceService. You should not change the Listener unless you intend to manage the lifecycle of that service. The DeviceService will proxy all of its Listener method calls through the ConnectableDevice's ConnectableDeviceListener.

Connection & Pairing

Your ConnectableDevice object will let you know if you need to connect or pair to any services.

Capabilities

All DeviceService objects have a group of capabilities. These capabilities can be implemented by any object, and that object will be returned when you call the DeviceService's capability methods (launcher, mediaPlayer, volumeControl, etc).

Inner Classes

Methods

void connect ()

Will attempt to connect to the DeviceService. The failure/success will be reported back to the DeviceServiceListener. If the connection attempt reveals that pairing is required, the DeviceServiceListener will also be notified in that event.

void disconnect ()

Will attempt to disconnect from the DeviceService. The failure/success will be reported back to the DeviceServiceListener.

boolean isConnected ()

Whether the DeviceService is currently connected

boolean isConnectable ()
void cancelPairing ()

Explicitly cancels pairing in services that require pairing. In some services, this will hide a prompt that is displaying on the device.

void sendPairingKey (String pairingKey)

Will attempt to pair with the DeviceService with the provided pairingData. The failure/success will be reported back to the DeviceServiceListener.

Parameters:
  • pairingKey –

    Data to be used for pairing. The type of this parameter will vary depending on what type of pairing is required, but is likely to be a string (pin code, pairing key, etc).

List<String> getCapabilities ()
boolean hasCapability (String capability)

Test to see if the capabilities array contains a given capability. See the individual Capability classes for acceptable capability values.

It is possible to append a wildcard search term .Any to the end of the search term. This method will return true for capabilities that match the term up to the wildcard.

Example: Launcher.App.Any

Parameters:
  • capability –

    Capability to test against

boolean hasAnyCapability (String... capabilities)

Test to see if the capabilities array contains at least one capability in a given set of capabilities. See the individual Capability classes for acceptable capability values.

See hasCapability: for a description of the wildcard feature provided by this method.

Parameters:
  • capabilities –

    Set of capabilities to test against

boolean hasCapabilities (List<String> capabilities)

Test to see if the capabilities array contains a given set of capabilities. See the individual Capability classes for acceptable capability values.

See hasCapability: for a description of the wildcard feature provided by this method.

Parameters:
  • capabilities –

    List of capabilities to test against

boolean hasCapabilities (String... capabilities)

Test to see if the capabilities array contains a given set of capabilities. See the individual Capability classes for acceptable capability values.

See hasCapability: for a description of the wildcard feature provided by this method.

Parameters:
  • capabilities –

    Set of capabilities to test against

ServiceDescription getServiceDescription ()
ServiceConfig getServiceConfig ()
JSONObject toJSONObject ()
String getServiceName ()

Name of the DeviceService (webOS, Chromecast, etc)

void closeLaunchSession (LaunchSession launchSession, ResponseListener<Object> listener)

Closes the session on the first screen device. Depending on the sessionType, the associated service will have different ways of handling the close functionality.

Parameters:
  • launchSession –

    LaunchSession to close

  • listener –

    (optional) listener to be called on success/failure
