Not receiving updated values while registering to a property

[lavanyapisini]

I'm unable to receive the updated values of vendor property in the Android app, initially I'm getting some value when we are trying to getIntProperty for that Vendor property. We also have the code for registerCallback but not receiving the values when they are updated at VHAL layer.

It looks like a problem in your application. By the way, you can use this project (https://github.com/nkh-lab/car-api-hello-world) as an example application and also this manifest (https://github.com/nkh-lab/ aosp-ncar-manifest) to get the NCAR AOSP where the given VHAL is used with the mentioned application.

In VHAL layer we have already implemented "VENDOR_PARKING_LIGHTS_STATE" property, and the same property I'm trying to register from Android app, also we have taken the same Android code from here and just replaced the Vendor property of ours.

Please find the below app code:

---

private void registerVendorProperty() {
mCarPropertyManager.registerCallback(new CarPropertyManager.CarPropertyEventCallback() {
@OverRide
public void onChangeEvent(CarPropertyValue carPropertyValue) {
Log.d(TAG, "VENDOR_PARKING_LIGHTS_STATE: onChangeEvent(" + carPropertyValue.getValue() + ")");
mVendorTest1sCounterPropertyView.setPropValue(String.valueOf(carPropertyValue.getValue()));
}

        @Override
        public void onErrorEvent(int propId, int zone) {
            Log.d(TAG, "VENDOR_PARKING_LIGHTS_STATE: onErrorEvent(" + propId + ", " + zone + ")");
        }
    }, VendorProperty.VENDOR_PARKING_LIGHTS_STATE, CarPropertyManager.SENSOR_RATE_NORMAL);

}

We have tested this property at VHAL with GRPC server client and it is working fine, but not reaching to app.
