CastService¶

com.connectsdk.service.CastService

CastService provides capabilities for Google Chromecast devices. CastService acts as a layer on top of Google’s own Cast SDK, and requires the Cast SDK library to function. CastService provides the following functionality:

Media playback
Media control
Web app launching & two-way communication
Volume control

Using Connect SDK for discovery/control of Chromecast devices will result in your app complying with the Google Cast SDK terms of service.

Inherited 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).
