# ICarTelemetry Sample Client
|
||
|
|
|
||
|
|
This is a sample vendor service that sends `CarData` to car telemetry service.
|
||
|
|
|
||
|
|
## Running
|
||
|
|
|
||
|
|
**1. Quick mode - under root**
|
||
|
|
|
||
|
|
```
|
||
|
|
m -j android.automotive.telemetryd-sampleclient
|
||
|
|
|
||
|
|
adb remount # make sure run "adb disable-verity" before remounting
|
||
|
|
adb push $ANDROID_PRODUCT_OUT/vendor/bin/android.automotive.telemetryd-sampleclient /system/bin/
|
||
|
|
|
||
|
|
adb shell /system/bin/android.automotive.telemetryd-sampleclient
|
||
|
|
|
||
|
|
# Then check logcat and dumpsys to verify the results. The following command enables VERBOSE logs.
|
||
|
|
adb shell setprop log.tag.android.automotive.telemetryd@1.0 V
|
||
|
|
adb logcat -v color -b all -T 1000
|
||
|
|
```
|
||
|
|
|
||
|
|
**2. Under vendor**
|
||
|
|
|
||
|
|
To include it in the final image, add
|
||
|
|
`PRODUCT_PACKAGES += android.automotive.telemetryd-sampleclient` to
|
||
|
|
`//packages/services/Car/cpp/telemetry/cartelemetryd/products/telemetry.mk` (or other suitable mk file).
|
||
|
|
|
||
|
|
```
|
||
|
|
# this goes to products/telemetry.mk
|
||
|
|
|
||
|
|
PRODUCT_PACKAGES += android.automotive.telemetryd-sampleclient
|
||
|
|
```
|
||
|
|
|
||
|
|
The sampleclient doesn't automatically start during boot, to start manually, run:
|
||
|
|
`adb shell /vendor/bin/android.automotive.telemetryd-sampleclient`.
|
||
|
|
|
||
|
|
If you want to test it by running `init`, add these SELinux rules:
|
||
|
|
|
||
|
|
```
|
||
|
|
# this goes to sepolicy/private/cartelemetryd.te
|
||
|
|
|
||
|
|
type cartelemetryd_sample, domain;
|
||
|
|
type cartelemetryd_sample_exec, vendor_file_type, exec_type, file_type;
|
||
|
|
init_daemon_domain(cartelemetryd_sample)
|
||
|
|
```
|
||
|
|
|
||
|
|
```
|
||
|
|
# this goes to sepolicy/private/file_contexts
|
||
|
|
|
||
|
|
/vendor/bin/android\.automotive\.telemetryd-sampleclient u:object_r:cartelemetryd_sample_exec:s0
|
||
|
|
```
|
||
|
|
|
||
|
|
And create an `.rc` file:
|
||
|
|
|
||
|
|
```
|
||
|
|
# File: cartelemetryd-sampleclient.rc
|
||
|
|
# Don't forget to add `init_rc: ["cartelemetryd-sampleclient.rc"],` to the Android.bp
|
||
|
|
|
||
|
|
service cartelemetryd_sample /vendor/bin/android.automotive.telemetryd-sampleclient
|
||
|
|
class hal
|
||
|
|
user system
|
||
|
|
group system
|
||
|
|
oneshot # run once, otherwise init keeps restarting it
|
||
|
|
disabled # do not start automatically
|
||
|
|
```
|
