Android 未找到心率传感器（LG Watch Urbane）

我正在尝试使用MainActivity.java上的以下代码访问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"));

问题是我遇到了以下错误：

E/SensorManager: sensor or listener is null

发生该错误的原因是没有与心率类型相关的传感器。因此，我编写了一些代码，以便使用该方法获得传感器的完整列表。getSensorList（Sensor.TYPE_ALL），我得到了以下结果：

我在那里没有看到任何心率传感器，所以我不知道要从中获取数据，我必须使用哪种型号

谁知道我做错了什么

提前感谢。

请确保您的应用程序已定义并授予Body Sensors权限

核实：

<uses-permission android:name="android.permission.BODY_SENSORS"/>

存在于您的AndroidManifest.xml中

---

另外，通过检查手表上的权限设置来确保已授予权限：设置->权限->你的应用程序

是的，我添加了该设置，但我刚刚意识到我修改了mobile AndroidManifest.xml而不是wear AndroidManifest.xml。它现在比你还管用。
