该MyMqttService 类的大概逻辑就是开启服务后,调用init()方法初始化各个参数,包括服务器地址、用户名、密码等等,然后调用doClientConnection()方法连接MQTT服务器,iMqttActionListener用来监听MQTT是否连接成功,连接成功则订阅主题。mqttCallback为订阅主题的回调,收到消息后会执行该回调中的messageArrived()方法,拿到消息后...
MqttAndroidClient#connect(java.lang.Object，org.eclipse.paho.client.mqttv3.IMqttActionListener)
最后,我们使用mqttClient.connect()方法连接到服务端,并提供一个IMqttActionListener对象来处理连接成功和失败的情况。 发布和订阅消息 一旦我们成功连接到服务端,就可以使用MQTT协议进行发布和订阅消息。以下是一个发布和订阅消息的示例代码: importorg.eclipse.paho.client.mqttv3.IMqttDeliveryToken;importorg.eclipse.p...
