MqttAndroidClient的使用 MQTT协议特点MQTT是一个由IBM主导开发的物联网传输协议，它被设计用于轻量级的发布/订阅式消息传输，旨在为低带宽和不稳定的网络环境中的物联网设备提供可靠的网络服务。它的核心设计思想是开源、可靠、轻巧、简单，具有以下主要的几项特性：非常小的通信开销（最小的消息大小为 2 字节）；支持各种流行编程语言（包括C，Java，Ruby，Python 等等）且易于使用的客户端；支持发布 / 预定模型，简化应用程序的开发；提供三种不同消息传递等级，让消息能按需到达目的地，适应在不稳定工作的网络传输需求应项目要求使用MQTT协议实现客户端与服务端通信。Android端使用MqttAndroidClient实现MQTT通信：MqttAndroidClientMqttAndroidClient配置{timeline}{timeline-item color="#19be6b"} 添加依赖{/timeline-item}{timeline-item color="#19be6b"} 声明权限{/timeline-item}{timeline-item color="#19be6b"} 配置服务{/timeline-item}{timeline-item color="#19be6b"} 功能实现{/timeline-item}{/timeline}{mtitle title="添加依赖"/}在项目根目录下的build.gradle中添加：repositories { maven { url "https://repo.eclipse.org/content/repositories/paho-snapshots/" } }在app目录下的build.gradle中添加： dependencies { implementation 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.1.0' implementation 'org.eclipse.paho:org.eclipse.paho.android.service:1.1.1' //eventbus 各个组件之间进行通信 implementation 'org.greenrobot:eventbus:3.1.1' }{mtitle title="权限声明"/}在AndroidManifest.xml中添加： <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />{mtitle title="配置服务"/}在AndroidManifest.xml中添加： <service android:name=".MQTTService" android:enabled="true" android:exported="true" /> <service android:name="org.eclipse.paho.android.service.MqttService" />{mtitle title="功能实现"/}MQTTService.javaimport android.app.Service; import android.content.Intent; import android.os.Binder; import android.os.IBinder; import android.util.Log; import org.eclipse.paho.android.service.MqttAndroidClient; import org.eclipse.paho.client.mqttv3.IMqttActionListener; import org.eclipse.paho.client.mqttv3.IMqttDeliveryToken; import org.eclipse.paho.client.mqttv3.IMqttToken; import org.eclipse.paho.client.mqttv3.MqttCallbackExtended; import org.eclipse.paho.client.mqttv3.MqttConnectOptions; import org.eclipse.paho.client.mqttv3.MqttException; import org.eclipse.paho.client.mqttv3.MqttMessage; import org.greenrobot.eventbus.EventBus; public class MQTTService extends Service { private static MqttAndroidClient mqttAndroidClient;//声明 final String serverUri = "tcp://43.139.79.48:1883";//mqtt地址 String clientId = "hello";//客户端的ID public static String subscriptionTopic = "test";//订阅的主题 public static String publishTopic = "test";//发布的主题 public MQTTService() { } //与mainactivit之间通信的 class MyBinder extends Binder{ //activity与service之间进行通信的桥梁 } @Override public IBinder onBind(Intent intent) { // TODO: Return the communication channel to the service.
