From 533f49cc00b0846c4f2ebd763b86b917f5023cdc Mon Sep 17 00:00:00 2001 From: Naveen Bobbili Date: Mon, 25 Feb 2019 21:00:09 -0800 Subject: vshl-capabilities: This API is responsible for brokering capbilities related messages from voiceagents to apps and vice versa. Verbs exposed are navigation/publish navigation/subscribe phonecontrol/publish phonecontrol/subscribe playbackcontroller/publish playbackcontroller/subscribe guiMetadata/publish guiMetadata/subscribe This API exposes publish and subscribe methods for all the speech framework domains/capabilities. For eg. navigation, phonecontrol etc. This API is used by apps and low level voice agent binding to subscribe and publish these capability messages whenever applicable. This specific commit is for vshl-capabilities API.
