20. Client-Server Communication
Android
class MainActivity : AIButton.AIButtonListener
override fun onResult(response: AIResponse)
override fun onError(error: AIError)
override fun onCancelled()
* There are some other approaches.

Android
class MainActivity : AIButton.AIButtonListener
override fun onResult(response: AIResponse)
override fun onError(error: AIError)
override fun onCancelled()

22. Client-Server Communication
val config = AIConfiguration(Config.ACCESS_TOKEN,
SupportedLanguages.Japanese,
AIConfiguration.RecognitionEngine.System)
config.recognizerStartSound =
resources.openRawResourceFd(R.raw.test_start)
config.recognizerStopSound =
resources.openRawResourceFd(R.raw.test_stop)
config.recognizerCancelSound =
resources.openRawResourceFd(R.raw.test_cancel)
aiButton.initialize(config)
aiButton.setResultsListener(this)
Android

response: AIResponse
response.status
status.code 200
status.errorType success
response.result
result.resolvedQuery イカを注文したい
result.action input.order
result.fulfillment.speech いくつ必要ですか？
