I’m trying to record heart rate data from an emulated watch (running Wear OS 4/ API Level 14) and the most recent version of Android Studio Preview. I am using Android Studio’s PassiveMonitoringClient (Part of Android Studio Health Services). Here’s a snippet of the code that I just wrote in MainActivity OnCreate. Right now, I just want a minimum working example of reading in some heart rate data.

val healthClient = HealthServices.getClient(this)
val passiveMonitoringClient = healthClient.passiveMonitoringClient

val passiveListenerConfig = PassiveListenerConfig.builder()
    .setDataTypes(setOf(DataType.HEART_RATE_BPM, DataType.GOLF_SHOT_COUNT))
    .build()

val passiveListenerCallback: PassiveListenerCallback = object : PassiveListenerCallback {
    override fun onNewDataPointsReceived(dataPoints: DataPointContainer) {
        for (dataPoint in dataPoints.sampleDataPoints) {
            val heartRate = dataPoint.value
            Log.i("WearApp", "Received heart rate: $heartRate")
        }
    }
}

passiveMonitoringClient.setPassiveListenerCallback(
    passiveListenerConfig,
    passiveListenerCallback,
)

I am using adb commands to start the activity (walking):

adb shell am broadcast                                          
-a "whs.USE_SYNTHETIC_PROVIDERS"      
com.google.android.wearable.healthservices

and, subsequently,

adb shell am broadcast                                        
-a "whs.synthetic.user.START_WALKING" 
com.google.android.wearable.healthservices

The docs say that the start walking activity should start generating heart rate data, but my log line is never being printed, and I verified that the callback is never being called.

Note that I can verify that the adb is connected to the correct emulated device, but I’m unsure if the commands are working as intended.

I should have the relevant permissions in my manifest. Here it is just in case:

<uses-permission android:name="android.permission.BODY_SENSORS" />
<uses-permission android:name="android.permission.BODY_SENSORS_BACKGROUND"/>
<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION" />
<uses-permission android:name="android.permission.health.READ_HEART_RATE"/> 

I do not have any permission request setup in the app, it’s just a base project with this code to test the sensor reading for now before I incorporate it into my main app.

Thanks!
