android – 如何正确检索将数据插入Google Fit的应用程序的包名？

public void getActivitiesData(Date from,Date till) {
    DataReadRequest readRequest = new DataReadRequest.Builder()
        .aggregate(DataType.TYPE_ACTIVITY_SEGMENT,DataType.AGGREGATE_ACTIVITY_SUMMARY)
        .bucketByTime(1,TimeUnit.DAYS)
        .setTimeRange(from.getTime(),till.getTime(),TimeUnit.MILLISECONDS)
        .build();

    fitness.HistoryApi.readData(apiclient,readRequest).setResultCallback(new com.google.android.gms.common.api.ResultCallback<DataReadResult>() {
        @Override
        public void onResult(DataReadResult dataReadResult) {
            Status status = dataReadResult.getStatus();
            if (status.isSuccess()) {

                for (Bucket bucket : dataReadResult.getBuckets()) {
                    if (!bucket.getDataSets().isEmpty()) {
                        DataSet dataSet = bucket.getDataSets().get(0);
                        String sourceAppPackageName = getSourceAppPackageNameFromDataSet(dataSet);
                        for (DataPoint dp : dataSet.getDataPoints()) {
                            for (Field field : dp.getDataType().getFields()) {
                                String fieldName = field.getName();
                                if (fieldName != null && fieldName.equals("activity")) {
                                    String type = fitnessActivities.getValue(dp);
                                    Date from = new Date(dp.getStartTime(TimeUnit.MILLISECONDS));
                                    Date till = new Date(dp.getEndTime(TimeUnit.MILLISECONDS));

                                    // store retrieved values to the data object,omitted
                                }
                            }
                        }
                    }
                }
            }
        }
    });
}

private static String getSourceAppPackageNameFromDataSet(DataSet dataSet) {
    String result = null;

    if (dataSet.getDataSource() != null) {
        result = dataSet.getDataSource().getAppPackageName();
    }

    return result;
}

要将活动插入Google Fit,我使用了Google健身应用和Runkeeper(目前,这些应用似乎只是与Fit集成的应用).

我的代码按预期检索这些活动,但是,对于每个活动,我的getSourceAppPackageNameFromDataSet()方法返回“com.google.android.gms”作为包名.根据Data Attribution section in Google Fit documentation,我希望该方法返回Runkeeper或Google Fit的包名,但这不会发生.

我做了一些可怕的错误,或者这是Google Fit中的错误？
