Music

Design:

Proposal 1

Vaani will connect to music-controller IAC while Vaani receives a control commands, play, stop, pause, resume, previous, or next. No matter music app is opened or not, Vaani will open or connect to it at background and sends command to music app. Unlike mediacomms at system app, system app waits for playing state change to activate media widget at utility tray or lockscreen. Vaani uses music-controller in active mode.

In our UX spec, Vaani will ask music ask:

if music is playing
to play next song
to play previous song
to play all
to stop/pause playing
to resume playing
