Android Wear 2 WiFi本地网络访问

Question

我已经通过改造进行了一些REST调用，访问本地WiFi网络上的本地IP地址，在移动端工作得很好，但是一旦在独立的应用程序上，我就会出现这个错误：

如果我用在线IP地址替换本地IP地址，它也可以在手表上正常工作。在移动应用程序上没问题，我可以正确访问本地或远程相同的URL。两个设备都在相同的WiFi网络下。 有什么想法吗？

Answer 1

这个问题一直困扰着我。似乎是这样的情况是，当Android Wear通过蓝牙（以及手机）连接到互联网时，http / web呼叫以某种方式被代理。

解决方案是禁用手机的蓝牙连接，这会强制Android Wear设备直接连接到本地wifi（如果它首先支持wifi），然后本地API请求会神奇地开始工作。

更合适的解决方法（因为您无法在每次使用应用时确实要求用户断开与手机的蓝牙连接），似乎是使用NodeApi检查是否生成的电话节点在附近（使用Node.isNearby()），如果是，请使用MessageClient自行代理API请求，然后在电话上发出请求，最后回复结果。相当麻烦，但对我而言，这是唯一可靠的方式来调用本地API ...

如果有人知道为什么Google会通过蓝牙代理这些来电或者有其他建议来解决这个问题，我也很想知道。

Answer 2

当佩戴与移动设备连接时，在那种情况下使用移动互联网API代码无效。请从手机上断开磨损，然后再试一次它给你回复。 请查看此链接，我感谢您的帮助：https://www.sitepoint.com/connecting-to-web-services-with-android-wear/

Answer 3

Wear将使用共享蓝牙连接，活动接口类型将是PROXY但不是WIFI。你可以adb shell dumpsys netstats查看。在这种情况下，磨损不在服务器的同一本地网络中，服务器的套接字将超时。

一种解决方案是让您的服务器具有公共IP或主机名。另一种方法是在访问API之前使用NetworkRequest更改与wifi的连接。请查看Google的示例：https://github.com/googlesamples/android-WearHighBandwidthNetworking
