Permissions

The exact strings Google’s data-types table declares for HeartRateRecord. Google’s page: “Before requesting any permissions, your app must declare them in the manifest.”

<uses-permission android:name="android.permission.health.READ_HEART_RATE" />
<uses-permission android:name="android.permission.health.WRITE_HEART_RATE" />

import androidx.health.connect.client.permission.HealthPermission
import androidx.health.connect.client.records.HeartRateRecord

val permissions = setOf(
    HealthPermission.getReadPermission(HeartRateRecord::class),
    HealthPermission.getWritePermission(HeartRateRecord::class),
)

The 6 fields of HeartRateRecord

Types and descriptions as Google’s reference prints them. The range column quotes Google’s own range annotation or sentence; a dash means Google states none, which is not the same as no validation.

Aggregate metrics

The AggregateMetric constants Google defines on HeartRateRecord. The value type is the T in Google’s AggregateMetric<T> signature. Every aggregate metric across all records.

Google’s read-data guide: “For cumulative types like StepsRecord, use aggregate() instead of readRecords() to avoid double counting from multiple sources and improve accuracy.” and “The aggregation API also contains logic to handle duplicate records, and lessens the chances of rate limiting.”

Read HeartRateRecord in Kotlin

The shape of Google’s own read example, with HeartRateRecord and its names filled in. Get the client with HealthConnectClient.getOrCreate(context) after checking getSdkStatus.

import androidx.health.connect.client.HealthConnectClient
import androidx.health.connect.client.records.HeartRateRecord
import androidx.health.connect.client.request.ReadRecordsRequest
import androidx.health.connect.client.time.TimeRangeFilter
import java.time.Instant

suspend fun readHeartRate(
    client: HealthConnectClient,
    startTime: Instant,
    endTime: Instant,
): List<HeartRateRecord> {
    val response = client.readRecords(
        ReadRecordsRequest(
            HeartRateRecord::class,
            timeRangeFilter = TimeRangeFilter.between(startTime, endTime),
        )
    )
    // One page of up to pageSize records (default 1000); follow
    // response.pageToken for the rest.
    return response.records
}

import androidx.health.connect.client.HealthConnectClient
import androidx.health.connect.client.records.HeartRateRecord
import androidx.health.connect.client.request.AggregateRequest
import androidx.health.connect.client.time.TimeRangeFilter
import java.time.Instant

suspend fun aggregateHeartRate(
    client: HealthConnectClient,
    startTime: Instant,
    endTime: Instant,
): Long? {
    val response = client.aggregate(
        AggregateRequest(
            metrics = setOf(HeartRateRecord.BPM_AVG),
            timeRangeFilter = TimeRangeFilter.between(startTime, endTime),
        )
    )
    // get() is declared as returning a nullable value.
    return response[HeartRateRecord.BPM_AVG]
}

Questions

What permission does HeartRateRecord need?

Google's Health Connect data-types table (read 2026-10-03) declares android.permission.health.READ_HEART_RATE for reading HeartRateRecord and android.permission.health.WRITE_HEART_RATE for writing it, and says apps must declare permissions in the manifest before requesting them.

Which aggregate metrics does HeartRateRecord support?

Google's Jetpack reference defines 4 on HeartRateRecord: BPM_AVG (AggregateMetric<Long>), BPM_MAX (AggregateMetric<Long>), BPM_MIN (AggregateMetric<Long>) and MEASUREMENTS_COUNT (AggregateMetric<Long>). Pass them in the metrics set of an AggregateRequest and read each back from the AggregationResult.

Is HeartRateRecord an interval, instantaneous or series record?

Google's data-types table lists HeartRateRecord as Series, and defines that column as indicating "whether the data is recorded at an instant in time or over an interval". Its mandatory fields are samples, endTime, metadata and startTime.
