WearableListenerService - 智能手机无法找到磨损作为节点？

Question

我将智能手机连接到磨损模拟器，我使用Android Studio。

模拟器和我的手机应用都使用WearableListenerService并重写了onMessageReceived()，而模拟器能够使用MessageApi成功向手机发送消息，但设备无法发送一回 - 尽管模拟器将我的手机视为一个节点，但仍然找不到任何节点。我最初使用MessageEvent.getSourceNodeId()方法和MessageEvent提供的onMessageReceived()参数，但这也不起作用。

我的计划是发送信息给我的手机并让手机在电话后立即传回信息。

为了给我的磨损设备发消息，我是否需要在手机上做些什么？我按照许多指南的说明进行操作：两个applicationId都是一样的，目录是一样的，清单很好，我用Generate Signed APK ...仍然没有！

感谢。

用于向手机发送消息的代码：
