From 0479d7c79a7fd6f112e8dc7e45c009cf6602dbaa Mon Sep 17 00:00:00 2001 From: Steve Kondik Date: Thu, 14 Jan 2016 02:46:40 -0800 Subject: audiopolicy: Add notification when default effects are updated * In M, we now have the ability to define a default set of audio effect on a per-stream basis. This allows us to get around the problem of apps not sending the control intents so we can implement smart global effects for specific media types. * We still need a session id in order to get a handle and configure them from an app like AudioFX, so we'll need to add some plumbing in order to send an event to interested applications. * This patch implements the native side of this. The Java layer will call down thru AudioSystem and register a callback which will be invoked by the audio policy when default effects are updated on a stream. This callback will receive both the stream type as well as the session id. * Attaching this listener requires that the caller hold the MODIFY_AUDIO_ROUTING permission.
