How to do an aggregate search in the Android Health Connect API

Question

I’m trying to get a daily aggregate step count from Google's new Health Connect API:

val request = AggregateGroupByPeriodRequest(
        setOf(StepsRecord.COUNT_TOTAL),
        TimeRangeFilter.between(Instant.now().minus(10, ChronoUnit.DAYS), Instant.now()),
        Period.ofDays(1),
        setOf<DataOrigin>())
val response = client.aggregateGroupByPeriod(request)

But any aggregate queries that I execute result in this exception:

java.lang.IllegalStateException: Duration must be set with physical times

Suppressed: kotlinx.coroutines.DiagnosticCoroutineContextException: [StandaloneCoroutine{Cancelling}@850d063, Dispatchers.Main]

Any ideas what’s causing this or how to work around it? I can get non-aggregated data without a problem using client.readRecords().

The sample code used Instant, but you need to use LocalDateTime.

val startTime = LocalDateTime.now().minusMonths(1)
val endTime = LocalDateTime.now()

val response =
  healthConnectClient.aggregateGroupByPeriod(
    AggregateGroupByPeriodRequest(
      metrics = setOf(StepsRecord.COUNT_TOTAL),
      timeRangeFilter = TimeRangeFilter.between(startTime, endTime),
      timeRangeSlicer = Period.ofDays(1)
    )
  )
