Write data

The following examples show you how to write data as part of a common workflow.

Steps

The following code example shows how to write basic data inserting step counts:

suspend fun insertSteps(healthConnectClient: HealthConnectClient) {
    val stepsRecord =
        StepsRecord(
            count = 120,
            startTime = START_TIME,
            endTime = END_TIME,
            startZoneOffset = START_ZONE_OFFSET,
            endZoneOffset = END_ZONE_OFFSET,
        )
    healthConnectClient.insertRecords(listOf(stepsRecord))
}

Nutrition

The Nutrition data type in Health Connect is vast and comprehensive. It includes a wide variety of optional nutrient fields ranging from total carbs to vitamin D and vitamin E. Each data point represents the nutrients that were potentially consumed as part of a meal or food item.

The following code example shows how to insert nutrition data for a user who’s eaten a banana:

suspend fun insertNutrition(healthConnectClient: HealthConnectClient) {
    val banana =
        NutritionRecord(
            name = "banana",
            energy = 105.0.kilocalories,
            dietaryFiber = 3.1.grams,
            potassium = 0.422.grams,
            totalCarbohydrate = 27.0.grams,
            totalFat = 0.4.grams,
            saturatedFat = 0.1.grams,
            sodium = 0.001.grams,
            sugar = 14.0.grams,
            vitaminB6 = 0.0005.grams,
            vitaminC = 0.0103.grams,
            startTime = START_TIME,
            endTime = END_TIME,
            startZoneOffset = START_ZONE_OFFSET,
            endZoneOffset = END_ZONE_OFFSET,
        )
    healthConnectClient.insertRecords(listOf(banana))
}

Series data

The following code example shows how to write heart rate series data to Health Connect.

suspend fun insertHeartRateSeries(healthConnectClient: HealthConnectClient) {
    val heartRateRecord =
        HeartRateRecord(
            startTime = START_TIME,
            startZoneOffset = START_ZONE_OFFSET,
            endTime = END_TIME,
            endZoneOffset = END_ZONE_OFFSET,
            // records 10 arbitrary data, to replace with actual data
            samples =
                List(10) { index ->
                    HeartRateRecord.Sample(
                        time = START_TIME + Duration.ofSeconds(index.toLong()),
                        beatsPerMinute = 100 + index.toLong(),
                    )
                },
        )
    healthConnectClient.insertRecords(listOf(heartRateRecord))
}
