AOSP VHAL example project
Includes a dummy implementation of support for Google's SYSTEM properties hardware/interfaces/automotive/vehicle/2.0/types.hal and an example of extending with custom VENDOR properties vendor/nkh-lab/interfaces/automotive/vehicle/1.0/types.hal
Google's SYSTEM properties are not handled (only configured) but VENDOR properties are simulated. The values of some of them (e.g. VENDOR_TEST_1S_COUNTER, VENDOR_TEST_500MS_COUNTER) are simulated by timer, the value of others (e.g VENDOR_TEST_SYS_PROP) can be changed by setting the corresponding Android System Property, for example:
$ setprop debug.vendor.nkh-lab.VENDOR_TEST_SYS_PROP 6789
and value update on CAR API client side, e.g. on CAR API Hello World app:
- NCAR manifest - repo manifest project for getting AOSP source tree where given project is part of it
- NCAR device
- CAR API Hello World - Android CAR API usage example project
