1) external Amplifier, controlled by Android only (cross ECU itnerface interface used by headunit only)
2) interact of an Android Audio ECU with the rest of the audio system other ECUs (e.g. remote control - e.g. non Android system)
3) interact with the Audio System from a server
...
-prevent fragmentation by collecting a survey about state of the art
- MPRIS dbus standard
1) Bluetooth : the AVRCP allows to control
2) Project Mode : / Audroid Auto - has virtual key input generator (volume up/down,...)
3) the same infrastructure from Project mode : can be used to inject the same as if it was a projected mode
4) Automotive : specific vehicle HAL service vehicle bus and converts in Android key codes
Android input system
Q: if volume key up/down limited to current volume ?
A: in automotive concept of volume groups which has the focus
Q: If the same interface include the audio settings
A: no intended in that interface
A: done through the audio effects HAL which is manufacturer specific

Q: What to develop next in the project
- Organization of the Android build
=> scripting the build ongoing, testing,...
Q: interest in AVB networked devices ?
- control / routing
- available AVB in automotive / professional audio
- https://github.com/Avnu/OpenAvnu
- Android (no many echos about AOSP/AVB)
- NXP/Renesas/ : board has AVB support
- Hikey 960 does not support AVB
- HW mandatory, not only low cost but automotive HW
- Android 11 support for Dragonboard
=> TODO organise an AVB introduction next week 26/11/2020
(TSN wider scope : https://en.wikipedia.org/wiki/Time-Sensitive_Networking)
Q: Any close to Android transport protocol or if it's part of the applications
A: usually part of the applications
A: approach interfacing Android system from outside like any Android app would do
