Implement special input handling

- Implement special input handling for seat.
  Each input event is handled per seat.
  Vehicle HAL sends the property for key and motion including
  the seat information.
- Special keys : Home, Power key
- Some keys (Media, Volume) can be handled by listener.
- Any other keys and motion events : inject to core system.

Fix: 259999340
Fix: 260000063
Test: atest CarInputServiceTest InputEventHelperTest
Test: manual test
1. send home key (for each seat in emulator)
  adb shell cmd car_service inject-key -s 0x1 3
  adb shell cmd car_service inject-key -s 0x4 3
  adb shell cmd car_service inject-key -s 0x10 3
2. send click event
  adb shell cmd car_service inject-motion -s 0x4 300 350

C++

Native (C++) code format is required to be compatible with .clang-format file. The formatter is already integrated to repo tool. To run manually, use:

git clang-format --style=file --extension='h,cpp,cc' HEAD~

Note that clang-format is not desirable for Android java files. Therefore the command line above is limited to specific extensions.

Debugging CarService

Dumpsys and car shell can be useful when debugging CarService integration issues.

dumpsys

adb shell dumpsys car_service # to dump all car service information
adb shell dumpsys car_service --services [service name] # to dump a specific service information
adb shell dumpsys car_service --list # get list of available services

Dumpsys for CarService includes the following (more information is availble in dumpsys, below are just highlights):

  • Enabled features
  • Current power policy and list of registered power policies
  • Power state of componens of power policy
  • Silent mode status
  • Garage mode status
  • I/O stats
  • List of available vehicle properties

car shell

adb shell cmd car_service

CarService supports commands via car shell:
(list is not complete, run adb shell cmd car_service -h for more details)

  • Injection of vhal events
  • Toggling garage mode on/off
  • Toggling of suspend/hibernation/resume
  • Injection of input events
  • User managemnet/switching
  • Power policy control/manipulation

Helpful command for Garage mode

Start Garage mode

adb shell cmd car_service garage-mode on

Finish Garage mode

adb shell cmd car_service garage-mode on

Get Garage mode status

adb shell cmd car_service garage-mode query

Change Garage mode max duration (only eng and debug builds)

adb shell setprop android.car.garagemodeduration <seconds>
