# Automotive Telemetry Service
|
||
|
|
|
||
|
|
A structured log collection service for CarTelemetryService. See ARCHITECTURE.md to learn internals.
|
||
|
|
|
||
|
|
## Useful Commands
|
||
|
|
|
||
|
|
**Dumping the service information**
|
||
|
|
|
||
|
|
`adb shell dumpsys android.automotive.telemetry.internal.ICarTelemetryInternal/default`
|
||
|
|
|
||
|
|
**Enabling VERBOSE logs**
|
||
|
|
|
||
|
|
```
|
||
|
|
adb shell setprop log.tag.android.automotive.telemetryd@1.0 V
|
||
|
|
adb shell setprop log.tag.cartelemetryd_impl_test V
|
||
|
|
```
|
||
|
|
|
||
|
|
**Starting emulator with cold boot**
|
||
|
|
|
||
|
|
`emulator -verbose -show-kernel -selinux permissive -writable-system -no-snapshot -wipe-data`
|
||
|
|
|
||
|
|
**Running the tests**
|
||
|
|
|
||
|
|
`atest cartelemetryd_impl_test:CarTelemetryInternalImplTest#TestSetListenerReturnsOk`
|
||
|
|
|
||
|
|
`atest cartelemetryd_impl_test`
|
||
|
|
|
||
|
|
## Enabling cartelemetryd
|
||
|
|
|
||
|
|
`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.
|
||
|
|
ifneq ($(filter $(TARGET_PRODUCT), TARGET1 TARGET2),)
|
||
|
|
include packages/services/Car/cpp/telemetry/cartelemetryd/products/telemetry.mk
|
||
|
|
endif
|
||
|
|
```
|
||
|
|
|
||
|
|
To find where the service was included, run this from `$ANDROID_BUILD_TOP`:
|
||
|
|
|
||
|
|
```
|
||
|
|
grep -rH --color --exclude-dir='**/.*' --exclude-dir='out' --include='*.mk' \
|
||
|
|
'cartelemetryd/products/telemetry.mk' device/ vendor/
|
||
|
|
```
