Support for this will be enabled by an upcoming Health Services release in the Google Play Store and can be checked via exercise capabilities. Note: batching modes take effect while the device is in a non-interactive power state, and will cause increased power consumption.

API Changes

  • Throwing HealthServicesException when suspend function overrideBatchingModesForActiveExercise fails (Ifd387)
  • Introduced suspend functions for async overrideBatchingModesForActiveExercise API making them more kotlin friendly (I7dd15)

Version 1.0.0-beta01

October 24, 2022

New Features

  • Added the ability to listen for health events through PassiveMonitoringClient with the first event being: HealthEvent.FALL_DETECTED.

  • New ExerciseTypes:

    • ALPINE_SKIING
    • BACKPACKING
    • CROSS_COUNTRY_SKIING
    • HORSE_RIDING
    • INLINE_SKATING
    • MOUNTAIN_BIKING
    • ORIENTEERING
    • ROLLER_SKATING
    • YACHTING

  • New DataTypes:

    • ELEVATION_LOSS
    • GOLF_SHOT_COUNT

API Changes

  • Updated how data is modeled: the data model and how DataTypes, DataPoints, and their underlying values are represented have been overhauled. The top level impact is that APIs are now much more explicit and type safe.
  • Location DataPoints are no longer represented as a DoubleArray, but instead as a strongly-typed LocationData object.
  • Moved to a new set of passive listener APIs:
    • The broadcast was replaced by the PassiveListenerService.
    • The existing listeners were replaced with a single listener: PassiveListenerCallback.
  • Added <queries> tag to Health Services manifest so that applications no longer need to specify this in their own manifest (provided manifest merger is turned on in their build system.)
  • Moved away from many ExerciseStates to represent the exercise is ending / ended and added new exercise states ENDING and ENDED. These are now combined with ExerciseEndReason to represent the full gamut of previous states.
  • Renamed PassiveListenerConfig setPassiveGoals to setDailyGoals to better reflect we only support daily passive goals.
  • PassiveGoals now always REPEATED, passive TriggerFrequency removed.
  • Annotated all Long and Double parameters with @FloatRange.
  • Added swimmingPoolLengthMeters property to ExerciseConfig which may be optionally specified to improve distance calculations for pool swims.
  • Deprecated ExerciseUpdate.activeDuration. Use ExerciseUpdate.activeDurationCheckpoint instead.
  • Renamed the API flushExerciseAsync() to flushAsync() in ExerciseClient.
  • Measure.registerCallback renamed to Measure.registerMeasureCallback.
  • General naming changes:
    • Distance properties now have meters suffix.
    • Callback method names are now past tense.
    • Most abbreviations have been removed (HrAccuracy is now HeartRateAccuracy.)
    • Properties following the pattern enableFoo are now named isFooEnabled.
  • Migrated away from Enums.
  • Times represented by Double are now represented by Duration.
  • Functions returning a ListenableFuture<Void?> now return a ListenableFuture<Void>.
  • Functions that accept a callback now always have the callback appear as the last parameter.
  • Classes with builders now always also have public constructors.
  • Registration functions no longer return a ListenableFuture and instead pass registration status to the provided callback.
  • KDocs have now been improved.
  • Public classes no longer extend ProtoParcelable.

Bug Fixes

  • General improvements to IPC reliability (I3b1e2)

Version 1.0.0-alpha03

November 3, 2021

androidx.health:health-services-client:1.0.0-alpha03 is released. Version 1.0.0-alpha03 contains these commits.

New Features

  • The SDK will automatically re-register measure, exercise listener, and passive monitoring callback registration requests in the event that the IPC connection is broken with the Health Services APK.

API Changes

  • minSdkVersion of the SDK library bumped to API level 30 since the Health Services Client is currently only supported on Wear3.

Version 1.0.0-alpha02

September 29, 2021

androidx.health:health-services-client:1.0.0-alpha02 is released. Version 1.0.0-alpha02 contains these commits.

API Changes

  • ExerciseClient now supports preparing an exercise. This allows clients to warm-up the sensors and wait for things like a GPS Fix before starting exercise.
  • Introduces CumulativeDataPoints and StatisticalDataPoints AggregateDataPoint classes to better model aggregate metrics tracked during an active exercise. CumulativeDataPoints hold cumulative values of aggregated interval data types (such as total distance during the exercise) while StatisticalDataPoints model aggregates of sampled data points (such as min, max, and average HeartRateBpm). This replaces the previous AGGREGATE_* DataTypes and can be accessed in the ExerciseUpdate via getLatestAggregateMetrics(). AGGREGATE_* DataTypes are no longer supported.
  • PassiveMonitoring Events have been renamed to PassiveGoals which supports setting of goals and receiving notifications when those goals are met for data types like Daily metrics (i.e. DAILY_STEPS).
  • Improved modeling of Heart Rate and Location accuracy and availability via the introduction of the new HrAccuracy, LocationAccuracy, and LocationAvailability classes.
  • Improved naming of ExerciseConfig and new PassiveMonitoringConfig fields and introduction of ExerciseConfig.shouldEnableGps to request GPS-backed data

Bug Fixes

  • Migrates to proto-backed IPC transport for better backwards compatibility support

Version 1.0.0-alpha01

May 18, 2021

androidx.health:health-services-client:1.0.0-alpha01 is released. Version 1.0.0-alpha01 contains these commits.

Features of initial release

The Health Services library provides a uniform set of APIs for developers to integrate with device-specific sensor implementations. It will work out of the box with Wear OS 3 emulators and upcoming devices, with additional platforms supported in the future. Three top level API surfaces are included in this initial release: The ExerciseClient, PassiveMonitoringClient, and MeasureClient.

ExerciseClient

The ExerciseClient is made for applications tracking active workouts, with up to 82 different ExerciseTypes from walking and running to dancing and water polo. While tracking these exercises, there’s a selection of 50 different DataTypes available depending on the exercise type and hardware available on the device. To get started, just specify the relevant information in your ExerciseConfig, call exerciseClient.startExercise and listen for progress on the update listener.

PassiveMonitoringClient

The PassiveMonitoringClient is a great choice if your application tracks the user’s activity throughout the day. You can register a PendingIntent with a set of DataTypes and be woken up to handle batched changes. Alternatively, you can specify an Event such as reaching a certain number of steps.

MeasureClient

Sometimes the user needs to measure e.g. their heart rate in the moment, not during an exercise and not throughout the day. In those moments the MeasureClient is the perfect choice.You just register your callback with supported DataTypes to receive a stream of data, unregistering your callback when it’s no longer needed.
