找不到心率传感器(LG Watch Urbane) [英] Heart Rate Sensor not found (LG Watch Urbane)
问题描述
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:
I'm trying to access to the heart rate sensor of my LG Watch Urbane using this code on MainActivity.java:
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"));
问题是我收到此错误:
E/SensorManager: sensor or listener is null
发生此错误是因为没有与TYPE_HEART_RATE相关联的传感器.因此，我编写了一些代码，以使用方法.getSensorList(Sensor.TYPE_ALL)来获取传感器的完整列表，我得到了:
That error happens because there isn't a sensor with TYPE_HEART_RATE associated. So, I wrote some code in order to get the full list of sensors with the method .getSensorList(Sensor.TYPE_ALL) and I got this:

我在那里没有看到任何心率传感器，所以我不知道为了从中获取数据我必须使用哪种类型的数字.
I don't see any heart rate sensor there, so I don't know what type number I have to use in order to get data from it.
有人知道我在做什么错吗?
Anyone knows what am I doing wrong?
谢谢.
推荐答案
确保您的应用程序已定义并授予身体传感器"权限.
Ensure that your application has defined and granted the Body Sensors permission.
验证:
<uses-permission android:name="android.permission.BODY_SENSORS"/>
存在于您的AndroidManifest.xml
is present in your AndroidManifest.xml
此外，请通过检查手表上的权限"设置来确保已授予该权限:设置"->权限"->您的应用"
Also, ensure that the permission has been granted by checking the Permissions settings on the watch: Settings -> Permissions -> Your app
