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>
