* Implemented by an application that wants to offer detection for hotword. The service can be used
* for both DSP and non-DSP detectors.
*
* The system will bind an application's {@link VoiceInteractionService} first. When {@link
* VoiceInteractionService#createHotwordDetector(PersistableBundle, SharedMemory,
* HotwordDetector.Callback)} or {@link VoiceInteractionService#createAlwaysOnHotwordDetector(
* String, Locale, PersistableBundle, SharedMemory, AlwaysOnHotwordDetector.Callback)} is called,
* the system will bind application's {@link HotwordDetectionService}. Either on a hardware
* trigger or on request from the {@link VoiceInteractionService}, the system calls into the
* {@link HotwordDetectionService} to request detection. The {@link HotwordDetectionService} then
* uses {@link Callback#onDetected(HotwordDetectedResult)} to inform the system that a relevant
* keyphrase was detected, or if applicable uses {@link Callback#onRejected(HotwordRejectedResult)}
* to inform the system that a keyphrase was not detected. The system then relays this result to
* the {@link VoiceInteractionService} through {@link HotwordDetector.Callback}.
