- Defines schema for enrollment apps to publish metadata for the search
keyphrase. This metadata consists of an ID, a user visible keyphrase,
and the target package to handle the keyphrase, when it triggers.
- Reads the metadata and populates the KeyphraseInfo object for access via
the VoiceInteractionService
- Adds permission and intent action for the enrollment app.
The enrollment app needs to be a system app protected with the
MANAGE_VOICE_KEYPHRASES permission and the activity performing the
enrollment needs to handle the ACTION_MANAGE_VOICE_KEYPHRASES
- The keyphrase info currently stores an ID - that's for internal
bookkeeping only, a keyphrase text - that's used by the public APIs,
and a list of supported locales, which isn't exposed but is used while
indicating if hardware hotword is available for a particular keyphrase
in a language or not.
