A driver only glances at the screen, so short toasts now last 4 seconds and long
ones 7. The card uses the popup's colours, which read better over a map.
Cars like the 2022 Dacia Jogger list a compressed audio channel before the raw one, and Gearslip was sending raw audio to it. The Exit tile no longer shows as running, and the log leaves out the weather town and the car's GPS.
LIVI lists an empty input for its cluster display before the real touchscreen, so every
tap was ignored. Pick the video and input that belong to the main screen.
Sensors live in service field 2, not 5 (that's the mic), so the channel never opened.
Message ids were also one off and the start request was missing min_update_period.
The head unit offers a media sink, but Android answers Setup with an
empty reply instead of a Config message. AudioLink now falls back to
the advertised sink after 2.5s. AudioCaptureService captures by audio
usage, not by app, so switching media apps costs nothing further and
one grant covers a whole drive.
A one-time adb command (PROJECT_MEDIA) removes the consent dialog
itself; the setup screen now includes it as a copyable step, next to
the existing mic-permission step.
Capture counts as a screen share, so Android 15 hides notification
contents while it runs. ScreenShareGuard lifts that protection for
the length of the capture, with a second adb grant
(WRITE_SECURE_SETTINGS), and restores it afterward, including after a
crash.
The phone keeps playing what it captures, so AudioCaptureService also
mutes STREAM_MUSIC for the drive and restores it on every exit path.
Adds a debug bench (BenchAudioSink, CarPreviewActivity --ez audio
true) for testing the audio path without a car, and a unit test that
rebuilds the real head unit's ServiceDiscoveryResponse from a logged
session to confirm the media and guidance sinks are found correctly.
