没有找到心率传感器（LG Watch Urbane）
我正尝试使用MainActivity.java上的此代码访问我的LG Watch Urbane的心率传感器：
mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
mHeartRateSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_HEART_RATE);
boolean sensorRegistered = mSensorManager.registerListener(this, mHeartRateSensor, SensorManager.SENSOR_DELAY_NORMAL);
Log.d("Sensor Status:", " Sensor registered: " + (sensorRegistered ? "yes" : "no"));
问题是我得到这个错误：
E/SensorManager: sensor or listener is null
发生该错误是因为没有与TYPE_HEART_RATE关联的传感器。 所以，我编写了一些代码，以便通过方法.getSensorList（Sensor.TYPE_ALL）获得完整的传感器列表，并且我得到了这个：

我没有在那里看到任何心率传感器，所以我不知道我必须使用什么类型的数字才能从中获取数据。
任何人都知道我做错了什么？
提前致谢。
