Android Auto getting data about car

Question

I'm trying to display all possible information about vehicle when android auto is connected to my android app.

Unfortunately I get nulls everywhere.

I'm using Desktop Head Unit emulator and actual mobile device. I also tested app on real vehicle, and it showed same results.

Method for getting information:

private fun getData() {
    Log.i(TAG, "getData()")
    val carService = carContext.getCarService(CarHardwareManager::class.java)
    val carInfo = carService.carInfo
    val carSensors = carService.carSensors

    textMap["Car App Api Level"] = carContext.carAppApiLevel.toString()
    textMap["Host info"] = carContext.hostInfo.toString()
    textMap["Is dark mode"] = carContext.isDarkMode.toString()

    try {
        carService.carClimate
        textMap["Car climate"] = "Available"
    } catch (t: Throwable) {
        textMap["Car climate"] = "Unavailable"
    }

    carSensors.addGyroscopeListener(UPDATE_RATE_NORMAL, carContext.mainExecutor) {
        textMap["Gyroscope"] = it.toString()
        invalidate()
    }

    carSensors.addCarHardwareLocationListener(UPDATE_RATE_NORMAL, carContext.mainExecutor) {
        textMap["Car Hardware Location"] = it.location.value.toString()
        invalidate()
    }

    carSensors.addCompassListener(UPDATE_RATE_NORMAL, carContext.mainExecutor) {
        textMap["Compass"] = it.orientations.value.toString()
        invalidate()
    }

    carSensors.addAccelerometerListener(UPDATE_RATE_NORMAL, carContext.mainExecutor) {
        textMap["Accelerometer"] = it.forces.value.toString()
        invalidate()
    }

    carInfo.fetchEnergyProfile(carContext.mainExecutor) {
        textMap["Energy Profile"] =
            it.fuelTypes.value.toString() + " " + it.evConnectorTypes.value.toString()
        invalidate()
    }

    carInfo.addTollListener(carContext.mainExecutor) {
        textMap["Toll Card"] = it.cardState.value.toString()
        invalidate()
    }

    carInfo.addSpeedListener(carContext.mainExecutor) {
        textMap["Speed"] =
            it.speedDisplayUnit.value.toString() + " " + it.rawSpeedMetersPerSecond.value.toString() + " " + it.displaySpeedMetersPerSecond.value.toString()
        invalidate()
    }

    carInfo.addMileageListener(carContext.mainExecutor) {
        textMap["Mileage"] = it.odometerMeters.value.toString()
        invalidate()
    }

    carInfo.addEvStatusListener(carContext.mainExecutor) {
        textMap["Ev Status"] =
            it.evChargePortConnected.value.toString() + " " + it.evChargePortOpen.value.toString()
        invalidate()
    }

    carInfo.addEnergyLevelListener(carContext.mainExecutor) {
        textMap["Energy level"] =
                    "Battery percent: " + it.batteryPercent.value.toString() +
                    ", Fuel percent: " + it.fuelPercent.value.toString() +
                    ", Distance display unit: " + it.distanceDisplayUnit.value.toString()
                    ", Energy is low: " + it.energyIsLow.value.toString() +
                    ", Fuel volume display unit: " + it.fuelVolumeDisplayUnit.value.toString() +
                    ", Range rmaining meters: " + it.rangeRemainingMeters.value.toString()

        invalidate()
    }

    carInfo.fetchModel(carContext.mainExecutor) {
        textMap["Model"] =
            "Name: " + it.name.value.toString() +
            ", Manufacturer: " + it.manufacturer.value.toString() +
            ", Value: " + it.year.value.toString()
        invalidate()
    }
}

Why are all fields null and how to fix it?
