Remarks

Returns the list of direct actions supported by the app.

You should return the list of actions that could be executed in the current context, which is in the current state of the app. If the actions that could be executed by the app changes you should report that via calling VoiceInteractor#notifyDirectActionsChanged().

To get the voice interactor you need to call #getVoiceInteractor() which would return non null only if there is an ongoing voice interaction session. You can also detect when the voice interactor is no longer valid because the voice interaction session that is backing is finished by calling VoiceInteractor#registerOnDestroyedCallback(Executor, Runnable).

This method will be called only after #onStart() and before #onStop().

You should pass to the callback the currently supported direct actions which cannot be null or contain null elements.

You should return the action list as soon as possible to ensure the consumer, for example the assistant, is as responsive as possible which would improve user experience of your app.
