How can I simulate datas from Heart Rate sensor on Android Wear Emulator?

Question

As the title, how can I do to "simulate" some values from the emulated heart rate sensor from the emulator? Is this possible on the official emulator or do you know some alternative emulators that do this?

Answer 1

No, you can't, android emulator can't simulate any sensors. Android Wear emulators can't do it too

Answer 2

Updating this answer for 2021. With the current emulator, you can click "..." in the emulator's menu and navigate to "Virtual Sensors -> Additional Sensors". Here you can move the heart rate slider to control it.

Answer 3

LOCATE HEART RATE VIRTUAL SENSOR

If you can not find the heart rate sensor under "Additional Sensors" as described in Scott's answer , you need to add this line below to your AVD's config.ini file.

hw.sensors.heart_rate=yes

For MacOS, the config.ini file can be found at this path:

/Users/{your user name}/.android/avd/{your AVD name}.avd/config.ini

INCLUDE PERMISSION:

You also need to request the android.permission.BODY_SENSORS .

This sensor requires permission android.permission.BODY_SENSORS. It will not be returned by SensorManager.getSensorsList nor SensorManager.getDefaultSensor if the application doesn't have this permission.

Source: Android Heart Rate Sensor documentation .

You can do that using the following methods:

 public void permissionRequest(){ if (checkSelfPermission(Manifest.permission.BODY_SENSORS).= PackageManager.PERMISSION_GRANTED) { requestPermissions( new String[]{Manifest.permission,BODY_SENSORS}; MY_PERMISSIONS_REQUEST_BODY_SENSOR). } else{ Log,d(TAG;"ALREADY GRANTED"); } }

OR you can enable it from Settings>Apps>YOUR_APP>Permissions>Sensor

Answer 4

You need implement function:

   // SensorValueListener
   @Override
   public void onHeartRate(long timestamp, int rate, int accuracy) {
          ....
   }

and then use the function:

   onHeartRate(timestamp, rate, accuracy);
