如何通过Health Connect获取Google Fit睡眠及骑行踏频数据？

需要将Google Fit中的睡眠及骑行追踪数据同步至自有应用，已知原Google Fit API已停用，需通过Health Connect实现数据获取。目前已成功获取多数类型数据，但睡眠数据和骑行踏频数据无法正常获取，相关代码实现如下：

HealthManager.kt #

class HealthManager(context : Context) :  ViewModel(){

    val permissions = setOf(
        HealthPermission.getReadPermission(SleepSessionRecord::class),
        HealthPermission.getReadPermission(CyclingPedalingCadenceRecord::class),
    )

    suspend fun readSleepInputs(start: Instant, end: Instant): List<SleepSessionRecord> {
        return try {
            val request = ReadRecordsRequest(
                recordType = SleepSessionRecord::class,
                timeRangeFilter = TimeRangeFilter.between(start, end)
            )
            val response = healthConnectClient.readRecords(request)
            response.records
        } catch (e: Exception) {
            Log.e("HealthConnect", "Error reading sleep records", e)
            emptyList()
        }
    }
    suspend fun readCyclePedalingCadence(start: Instant, end: Instant): List<CyclingPedalingCadenceRecord> {
        return try {
            val request = ReadRecordsRequest(
                recordType = CyclingPedalingCadenceRecord::class,
                timeRangeFilter = TimeRangeFilter.between(start, end)
            )
            val response = healthConnectClient.readRecords(request)
            response.records
        } catch (e: Exception) {
            emptyList()
        }
    }
}

DetailScreen.kt #

@Composable
fun DetailScreen(healthManager: HealthManager, navController: NavHostController) {

    val sleepRecords by produceState<List<SleepSessionRecord>>(initialValue = emptyList()) {
        value = healthManager.readSleepInputs(
            start = java.time.Instant.now().minus(30, ChronoUnit.DAYS),
            end = java.time.Instant.now()
        )
    }

    val cyclingCadence by produceState<List<CyclingPedalingCadenceRecord>>(initialValue = emptyList()) {
        value = healthManager.readCyclePedalingCadence(
            start = java.time.Instant.now().minus(30, java.time.temporal.ChronoUnit.DAYS),
            end = java.time.Instant.now()
        )
    }
    
    if (sleepRecords.isNotEmpty()) {
        Text(text = "Sleep Records:", fontWeight = FontWeight.Bold, fontSize = 18.sp)
        sleepRecords.forEach { record ->
            Text(text = "Sleep Records: ${record.stages}")
        }
    } else {
        Text(text = "No sleep records available.")
    }

    Spacer(modifier = Modifier.height(24.dp))

    if (cyclingCadence.isNotEmpty()) {
        Text(
            text = "Cycling Cadence Records:",
            fontWeight = FontWeight.Bold,
            fontSize = 18.sp
        )
        cyclingCadence.forEach { record ->
            Text(text = "Cycling Cadence Records: ${record.samples.firstOrNull()?.revolutionsPerMinute} rpm")
        }
    } else {
        Text(text = "No cycling cadence records available.")
    }
    
}

1. 权限配置与申请 #

• 确保AndroidManifest.xml中添加了对应权限：

  <uses-permission android:name="android.permission.health.READ_SLEEP" />
  <uses-permission android:name="android.permission.health.READ_CYCLING_PEDALING_CADENCE" />
  

• 代码中仅声明权限不够，需在运行时通过HealthConnectClient.requestPermissions()主动申请，确认用户已授权。

2. 睡眠数据获取优化 #

• 部分数据源会将睡眠阶段数据单独存储在SleepStageRecord中，而非SleepSessionRecord的stages字段，需同时读取该类型数据：

  suspend fun readSleepStages(start: Instant, end: Instant): List<SleepStageRecord> {
      return try {
          val request = ReadRecordsRequest(
              recordType = SleepStageRecord::class,
              timeRangeFilter = TimeRangeFilter.between(start, end)
          )
          healthConnectClient.readRecords(request).records
      } catch (e: Exception) {
          Log.e("HealthConnect", "Error reading sleep stages", e)
          emptyList()
      }
  }
  

• 打开Health Connect应用确认Google Fit的睡眠数据已同步至其中。

3. 骑行踏频数据排查 #

• 在readCyclePedalingCadence的catch块添加日志输出，定位具体错误：

  catch (e: Exception) {
      Log.e("HealthConnect", "Error reading cycling cadence", e)
      emptyList()
  }
  

• 确认healthConnectClient已正确初始化：

  private val healthConnectClient by lazy {
      HealthConnectClient.getOrCreate(context)
  }
  

• 踏频数据可能关联至CyclingSessionRecord，可尝试读取骑行会话数据，关联查询踏频信息。

4. 时间范围校验 #

• 确认Instant时间范围匹配数据存储的时区（Instant为UTC时间，需确保与Google Fit同步到Health Connect的时间一致）。
