- 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.
