推荐答案

您需要：

在它运行在服务器端的MQTT经纪人。这可能是有点像mosquitto经纪人这是开源的。 在一个MQTT客户机库，在你的Andr​​oid应用包含，使您的应用程序连接，订阅和发布消息。有一些列在 http://mqtt.org/software Java选项 要拿出唯一标识用户或设备的方式，然后使用它作为一个议题，使您可以单独发布一个消息到一个设备。 an MQTT broker which runs on the server side. This could be something like the mosquitto broker which is Open Source. an MQTT client library which you include in your Android app, enabling your app to connect, subscribe, and publish messages. There are a number of Java options listed at http://mqtt.org/software to come up with a way of uniquely identifying users or devices, and then use that as a topic so that you can individually publish a message to one device.
