【问题描述】：
我尝试（就像在所描述的主题中一样）插入和阅读睡眠作为健身活动。主要目标是分析单个会话的整个睡眠（何时是浅/深睡眠以及多长时间）。 连接到 GoogleFit 成功。 但我在数据点和数据会话方面遇到了麻烦。 也许你可以帮助我。 谢谢大家：D
我认为我有麻烦的一点代码。 我知道不清楚的代码。我试图复制我试图粘贴。在某些地方，名称不合适。但正如我提到的。我试图弄清楚睡眠期间的浅睡眠和深睡眠阶段。 我用 Sonyband 2 收集这个日期。

【问题讨论】：
-
这可能仍然取决于您如何write/record the activity。基于这些文件 - How do Garmin devices measure deep sleep vs light sleep?、The 4 Basics Of Sleep Tracking 和 Sleep monitors explained: Rest longer and feel better；它可能仍然取决于记录并计算深度/轻度睡眠。
-
最后，要读取睡眠数据，请像处理正常健身活动一样查询睡眠时段的睡眠活动段 - Release Notes。希望这会有所帮助。
