[SOLVED] Android Sleep API Codelab on Watch: API is not supported yet

Android Sleep API Codelab on Watch: API is not supported yet

I am trying to run the Android Sleep API Codelab (source code on GitHub) to run directly on a Pixel Watch 2

Under Settings > System > About

Wear OS by Google 4.0

Model Google Pixel Watch 2

Under Settings > System > About > Versions

Build number TWD9.240205.001.A

Wear Core Services 1.8.1.561085711

System UI 1.6.32.567711630

Google Play Services 23.42.12 (240304-574052649)

Android security patch March 5, 2024

I made only minor changes in the AndroidManifest.xml to run on the watch:

<uses-feature android:name="android.hardware.type.watch" />
<meta-data android:name="com.google.android.wearable.standalone" android:value="true" />

Following the instructions in the codelab, when running this code:

val task = ActivityRecognition.getClient(context).requestSleepSegmentUpdates(
   pendingIntent,
   // Registers for both SleepSegmentEvent and SleepClassifyEvent data.
   SleepSegmentRequest.getDefaultSleepSegmentRequest()
)

task.addOnSuccessListener {
   mainViewModel.updateSubscribedToSleepData(true)
   Log.d(TAG, "Successfully subscribed to sleep data.")
}
task.addOnFailureListener { exception ->
   Log.d(TAG, "Exception when subscribing to sleep data: $exception")
}

The following exception is logged:

Exception when subscribing to sleep data: java.lang.SecurityException: This API is not supported yet.

What would cause the API not to be supported? The Fitbit app correctly records sleep data overnight

Solution

It seems that it is not supported on wearables if you check https://developers.google.com/android/reference/com/google/android/gms/location/ActivityRecognitionClient#requestSleepSegmentUpdates(android.app.PendingIntent,%20com.google.android.gms.location.SleepSegmentRequest)

This API is not supported for wearable devices. Devices with the system feature of PackageManager#FEATURE_WATCH don't receive detection callbacks from this API.
