Add model management API skeleton to VoiceInteractionManagerService
Add an "interactor" for all always-on APIs
- The VoiceInteractionService will get an interactor for the given
keyphrase and locale.
- It can then check the availability and call methods to start and
stop recognition on this interactor.
- Add a common class to deal with SoundTrigger APIs
- Cleanup the keyphrase representation:
We now have separate representations for the keyphrase metadata and
a keyphrase being used for recognition.
This'll also help us to handle custom keyphrases in the
future easily.
This also ensures that for use within the framework,
we rely on the ID of the KeyphraseInfo rather than comparing the
text everytime.
Add a callback for the AlwaysOnHotwordDetector
This callback should be passed in by the VoiceInteractionService and is used to notify it
of recognition events.
