Google Fit API是否仅在本地读取数据？

Question

我有2部使用Gmail的电话：电话1：安装Google Fit应用并将数据同步到Web [https://fit.google.com][1]

[电话2：未安装Google Fit应用，我使用Google Fit Api读取了步骤数据。但是它不能返回结果。

我的代码：

Fitness.getHistoryClient(this, GoogleSignIn.getLastSignedInAccount(this))
                .readDailyTotal(DataType.TYPE_STEP_COUNT_DELTA)
                .addOnSuccessListener { dataSet ->
                    val total = (if (dataSet.isEmpty)
                        0
                    else
                        dataSet.dataPoints[0].getValue(Field.FIELD_STEPS).asInt()).toLong()
                    Log.i(TAG, "Total steps: " + total)
                    txtStep.setText(total.toString())
                }
                .addOnFailureListener(
                        object : OnFailureListener {
                            override fun onFailure(e: Exception) {
                                Log.w(TAG, "There was a problem getting the step count.", e)
                            }
                        })

我必须在Phone 2上安装Google Fit应用吗？Google Fit API是否仅在本地读取数据？

我尝试使用。enableServerQueries（），但仍然无法返回数据。

val endTime = cal.timeInMillis
        cal.add(Calendar.DAY_OF_YEAR, -1)
        cal.set(Calendar.HOUR_OF_DAY, 23)
        val startTime = cal.timeInMillis
        var readRequest = DataReadRequest.Builder()
                .read(DataType.TYPE_STEP_COUNT_DELTA)
                .enableServerQueries()
                .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
                .build()
        Fitness.getHistoryClient(this, GoogleSignIn.getLastSignedInAccount(this))
                .readData(readRequest)
                .addOnSuccessListener { dataReadResult ->
                    var total =0
                    if (dataReadResult.buckets.size > 0) {
                            for (bucket in dataReadResult.buckets) {
                            val dataSets = bucket.dataSets
                            for (dataSet in dataSets) {
                                for (dp in dataSet.dataPoints) {
                                    for (field in dp.dataType.fields) {
                                        total=total + dp.getValue(field).asInt()
                                    }
                                }
                            }
                        }
                    } else if (dataReadResult.dataSets.size > 0) {

                        for (dataSet in dataReadResult.dataSets) {
                            for (dp in dataSet.dataPoints) {
                                for (field in dp.dataType.fields) {
                                    total=total + dp.getValue(field).asInt()
                                }
                            }
                        }
                    }
                    txtStep.setText(total.toString())
                }
                .addOnFailureListener(
                        object : OnFailureListener {
                            override fun onFailure(e: Exception) {
                                Log.w(TAG, "There was a problem getting the step count.", e)
                            }
                        })

仅当我从sync Google Fit Data单击Setting时才能读取数据>

如果您不想拥有Google Fit应用，则可以使用getRecordingClient
