以上是项目中的代码，即蓝牙低功耗连接和通知部分。我可以在 android wear（手表显示“正在听”，这意味着它们已连接）和 android 手机之间进行连接。但是，通知仅显示在手机中，我无法在 android wear 中收到通知。我的项目有什么问题？请给我一些帮助。非常感谢您。

您是否尝试过查看此支持页面？您可以尝试给出的故障排除步骤，然后在每个步骤后检查您的手表，以查看通知是否开始工作。​如果还是不行，请尝试将手表恢复出厂设置。重新启动手表似乎在短期内对大多数人有用，但问题可能会再次出现，有时很快。您还可以查看此Android Wear 通知问题论坛，看看给定的解决方法是否会有所帮助。
