|
| `rate` | `int`: how fast the sensor events are delivered. It should be one of[SENSOR_RATE_FASTEST](https://developer.android.com/reference/android/car/hardware/CarSensorManager#SENSOR_RATE_FASTEST),[SENSOR_RATE_FAST](https://developer.android.com/reference/android/car/hardware/CarSensorManager#SENSOR_RATE_FAST),[SENSOR_RATE_UI](https://developer.android.com/reference/android/car/hardware/CarSensorManager#SENSOR_RATE_UI),[SENSOR_RATE_NORMAL](https://developer.android.com/reference/android/car/hardware/CarSensorManager#SENSOR_RATE_NORMAL). Rate may not be respected especially when the same sensor is registered with different listener with different rates. Also, rate might be ignored when vehicle property raises events only when the value is actually changed, for example[SENSOR_TYPE_PARKING_BRAKE](https://developer.android.com/reference/android/car/hardware/CarSensorManager#SENSOR_TYPE_PARKING_BRAKE)will raise an event only when parking brake was engaged or disengaged. Value is[SENSOR_RATE_ONCHANGE](https://developer.android.com/reference/android/car/hardware/CarSensorManager#SENSOR_RATE_ONCHANGE),[SENSOR_RATE_NORMAL](https://developer.android.com/reference/android/car/hardware/CarSensorManager#SENSOR_RATE_NORMAL),[SENSOR_RATE_UI](https://developer.android.com/reference/android/car/hardware/CarSensorManager#SENSOR_RATE_UI),[SENSOR_RATE_FAST](https://developer.android.com/reference/android/car/hardware/CarSensorManager#SENSOR_RATE_FAST), or[SENSOR_RATE_FASTEST](https://developer.android.com/reference/android/car/hardware/CarSensorManager#SENSOR_RATE_FASTEST)
|
| Returns ||
|-----------|------------------------------------------------|
| `boolean` | if the sensor was successfully enabled.

| Throws ||
|----------------------------|---------------------------------------|
| `IllegalArgumentException` | for wrong argument like wrong rate |
| `SecurityException` | if missing the appropriate permission |
### unregisterListener
```
public void unregisterListener (CarSensorManager.OnSensorChangedListener listener,
int sensorType)
```
Stop getting sensor update for the given listener and sensor. If the same listener is used for other sensors, those subscriptions will not be affected.
