我为Android Wear开发了一些表盘（minSdkVersion = 21和targetSdkVersion = 23）并整合了Google Fit API for Android。
我使用Fitness.SensorsApi.add从华为手表和Fitness.RecordingApi.subscribe读取心率传感器数据，以将传感器数据同步到Google Fit。 它的工作原理：更新后的数据在Google健身应用和Google健身网页（https://fit.google.com/）中正确显示。
当我尝试在同一块手表上使用Fitness.HistoryApi.readData读取数据时，它完美无缺。 这是logcat输出：
Range Start: Mar 7, 2017
Range End: Mar 8, 2017
Number of returned DataSets is: 1
Data returned for Data type: com.google.heart_rate.bpm
Data point:
Type: com.google.heart_rate.bpm
Start: 08.03 - 02:01:38
End: 08.03 - 02:01:38
Field: bpm Value: 82.0
Field: bpm
Field: 2
Field: com.google.heart_rate.bpm
mLastHeartBPM: 82
然而，当我尝试从另一只手表访问相同的心率数据时，一台Sony Smartwatch 3运行与华为手表（Android Wear 1.5 - Google Play Services 10.2.98）相同的软件，它会不断阅读Google的旧数据适合。 这是logcat输出：
Range Start: Mar 7, 2017
Range End: Mar 8, 2017
Number of returned DataSets is: 1
Data returned for Data type: com.google.heart_rate.bpm
Data point:
Type: com.google.heart_rate.bpm
Start: 07.03 - 04:31:13
End: 07.03 - 04:31:13
Field: bpm Value: 70.0
Field: bpm
Field: 2
Field: com.google.heart_rate.bpm
mLastHeartBPM: 70
正如您所看到的，同样的startTime和endTime，但结果完全不同。 返回的数据是Google健身中存在的实际值，但它是旧的。
这是我用来访问Google健身数据的功能

我找不到解释。 代码似乎是正确的，它基于Google样本。
有人可以给我一个线索吗？
更新 这些是调试器中的DataReadResult值：
SONY
DataReadResult{status=Status{statusCode=SUCCESS, resolution=null}, dataSets=[DataSet{d:heart_rate.bpm:gms:default_heart_rate_bpm []}], buckets=[]}
HUAWEI
DataReadResult{status=Status{statusCode=SUCCESS, resolution=null}, dataSets=[DataSet{d:heart_rate.bpm:gms:default_heart_rate_bpm [RawDataPoint{[70.0]@[1488981101916291248, 1488981101916291248](0,1)}]}], buckets=[]}
DataPoint{[70.0]@[1488981101916291248, 1488981101916291248,raw=0,insert=0](d:heart_rate.bpm:gms:default_heart_rate_bpm r:heart_rate.bpm:HUAWEI WATCH:c528846c:ADPD153GGRI)}
Sony SmartWatch 3输入代码的else if (dataReadResult.getDataSets().size() > 0)部分，但Datapoint为空。
