# run a specific test atest cartelemetryd_impl_test:CarTelemetryInternalImplTest#TestSetListenerReturnsOk # run all tests atest cartelemetryd_impl_test
cartelemertryd service is by default not included in the final build. To include it on specific targets, add the following lines in necessary .mk files:
# Enable Automotive Telemetry Services (cartelemetryd) only on specific devices. ENABLE_CARTELEMETRY_SERVICE ?= true
To find where the service was included, run this from $ANDROID_BUILD_TOP:
grep -rH --color --exclude-dir='**/.*' --exclude-dir='out' --include='*.mk' \
'ENABLE_CARTELEMETRY_SERVICE' device/ vendor/
If AIDL interface were updated, run m -j and re-flash.
If implementation were updated, run:
m -j android.automotive.telemetryd@1.0 adb root && adb remount && adb push $ANDROID_PRODUCT_OUT/system/bin/android.automotive.telemetryd@1.0 /system/bin && adb shell /system/bin/android.automotive.telemetryd@1.0 Ctrl+C adb reboot
