从Smartwatch Android Wear到智能手机获取数据

我为android穿戴的moto360制作了一些应用程序（计步器，心率，录音机）。一切正常，但我不知道如何将数据保存在手表上以及如何访问智能手机上的数据。我已经设法向手表发送了消息，但是无法将数据从手表发送到手机。我可以将数据保存在智能手机上，但是我不知道如何在智能手表上进行管理。有人可以给我看一个教程或例子吗？太感谢了！

编辑：下面的以下代码用于跟踪Moto360上的心率，并且可以正常工作。我尝试将数据从手表转移到手机，因为我使用了本教程-> https://developer.android.com/training/wearables/data-layer/data-items.html

从android页面实现代码后，我无法在设备上运行项目！
