Question

所以我正在尝试使用android API阅读google fit历史记录，但我遇到了一个恼人的限制。我似乎只能阅读过去一周左右的历史，即使有更多的数据（根据谷歌适合的应用程序）。我用来读取数据的代码在

下面

    Calendar cal = Calendar.getInstance();
    Date now = new Date();
    cal.setTime(now);
    long endTime = cal.getTimeInMillis();
    cal.add(Calendar.MONTH, -1);
    long startTime = cal.getTimeInMillis();
    //long startTime = 0l;

    final SimpleDateFormat dateFormat = new SimpleDateFormat();
    Log.i(TAG, "Range start: " + dateFormat.format(startTime));
    Log.i(TAG, "Range end: " + dateFormat.format(endTime));

    DataReadRequest readRequest = new DataReadRequest.Builder()
            .aggregate(DataType.TYPE_STEP_COUNT_DELTA, DataType.AGGREGATE_STEP_COUNT_DELTA)
            .bucketByTime(1, TimeUnit.DAYS)
            .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
            .build();

    Fitness.HistoryApi.readData(client, readRequest).setResultCallback(
            new com.google.android.gms.common.api.ResultCallback<DataReadResult>() {

                @Override
                public void onResult(DataReadResult result) {
                    //Log.i(TAG, result.getStatus().getStatusMessage());
                    int i = 0;
                    for (Bucket bucket : result.getBuckets()) {
                        for (DataSet dataSet : bucket.getDataSets()) {
                            //Log.i(TAG, "Data returned for Data type: " + dataSet.getDataType().getName());
                            for (DataPoint dp : dataSet.getDataPoints()) {
                                Log.i(TAG, ++i + "");
                                Log.i(TAG, "Data point:");
                                Log.i(TAG, "\tType: " + dp.getDataType().getName());
                                Log.i(TAG, "\tStart: " + dateFormat.format(dp.getStartTime(TimeUnit.MILLISECONDS)));
                                Log.i(TAG, "\tEnd: " + dateFormat.format(dp.getEndTime(TimeUnit.MILLISECONDS)));
                                for (Field field : dp.getDataType().getFields()) {
                                    Log.i(TAG, "\tField: " + field.getName() +
                                            " Value: " + dp.getValue(field));
                                }
                            }
                        }
                    }
                }
            }
    );

然而根据logcat，有很多空的日子

默认情况下，您的请求将仅查询存储在设备上的本地数据。要包含来自Google服务器的数据，请将.enableServerQueries()添加到DataReadRequest.Builder：

DataReadRequest readRequest = new DataReadRequest.Builder()
        .aggregate(DataType.TYPE_STEP_COUNT_DELTA, DataType.AGGREGATE_STEP_COUNT_DELTA)
        .bucketByTime(1, TimeUnit.DAYS)
        .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
        .enableServerQueries()
        .build();

enableServerQueries()

启用查询Google Fit服务器以获取查询结果，以防万一   本地商店没有完整请求时间范围的数据。   服务器结果将与本地结果合并为一个DataSet。

Google Fit API历史记录限制？
