Notification playback synchronized with audio focus
PlayerProxy: more control options (pan, delayed start),
remove exceptions in method signatures.
Use delayed start on notification playback for better sync
between media apps and notifications
Disabled for now: support for AudioService (through
MediaFocusControl and PlaybackActivityMonitor) to enforce
audio ducking of focus owners losing audio focus with
AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK, and who don't
play audio that has a content labelled as CONTENT_TYPE_SPEECH.
This feature will be enabled when setting a VolumeShaper
on a player works.
Test: play music and play notification

AudioPlaybackConfiguration has a player control interface
An AudioPlaybackConfiguration contains an IPlayer
interface for system control of a player. It is not
exposed to non-system signature components.
AudioService, through PlaybackActivityMonitor, is monitoring
the death of the IPlayer so the matching player can get
unregistered in case it meets its maker.
Test: use vendor/google_toolbox/team/audio/cmds/ClPlaybackActivity

Notification of playback activity
AudioService keeps track of status of implementations of PlayerBase.
AudioService's PlaybackActivityMonitor maintains a list of
playback configurations for each PlayerBase, and a list
of clients that want to receive updates about the playback.
Playback activity clients can query the playback configuration
of the system through AudioManager, or register a callback
for updates. For clients with MODIFY_AUDIO_ROUTING permission
(system), the playback configurations contain more information
about each player (player type, uid, pid, state), and can see
all players, not just the "active" ones. The act of stripping
off data about the players that is not supposed to be seen
by non-system clients, is referred to as "anonymization". It
is implemented in system server, so no system data is ever
sent to playback activity clients without system permission.
More information about the AudioPlaybackConfiguration is
available in the SystemApi (uid, pid, player type, player state).
Test: run cts -m CtsMediaTestCases -t android.media.cts.AudioPlaybackConfigurationTest
