1、最方便的方法，使用dlc的module连接mqtt

步骤、1——导入dlc依赖和module

//dlc_mqttmoduleimplementation project(':garbagerecyclebox')//dlc公库implementation('com.github.DlcAndroidTeam123456:DlcCommonLibrary:1.0.31-simple') {exclude group: 'me.yokeyword', module: 'fragmentation'}

步骤、2——创建工具方法，调用即可

// MqttProxy.init(this);//dlc的mqtt类使用// MqttMgr.get().publish();//dlc发送mqtt对象

MqttMgr.get().publish(MqttInformation.GDJBHSX_RECEIVE, 0, openBackBean);

public static final String GDJBHSX_RECEIVE = "sdfyhsx_receive/" + DeviceUtil.getAndroidId();

/*** @author : LGQ* @date : /05/18 10* @desc :*/public class MqttProxy {private static Activity activity;public static void init(Context context) {activity = (Activity) context;DlcMqttConnectOptions dlcMqttConnectOptions = new DlcMqttConnectOptions(context,MqttInformation.SERVER_URI, MqttInformation.USER_NAME, MqttInformation.PASS_WORD);// MqttMgr.get().addSubscribeTopics(MqttInformation.GDJBHSX_PUSH_APKBG, 0);MqttMgr.get().addSubscribeTopics(MqttInformation.GDJBHSX_PUSH, 0);LgqLogutil.e("主题地址=== "+MqttInformation.GDJBHSX_PUSH);// MqttMgr.get().addSubscribeTopics(MqttInformation.GDJBHSX_PUSH_UDCOMPANY, 0);// MqttMgr.get().addSubscribeTopics(MqttInformation.GDJBHSX_PUSH_ERRORKE, 0);// MqttMgr.get().addSubscribeTopics(MqttInformation.GDJBHSX_PUSH_UPDATEAPK, 0);MqttMgr.get().init(context, dlcMqttConnectOptions, new BaseMqttCallBack() {@Overridepublic void messageArrived(String topic, String message, int messageId) {handleMessageArrived(topic, message, messageId);// ObServernotice.getInstance().notifyObserver(5481,5,message,null);LgqLogutil.e("mqtt注册成功sxxxx00000=== "+message);}@Overridepublic void onSuccess(DlcMqttToken asyncActionToken) {LgqLogutil.e("mqtt注册成功sxxxx");}@Overridepublic void onFailure(DlcMqttException e) {LgqLogutil.e("成功sxxxx1111111");}});}public static void onDestroy() {MqttMgr.get().onDestroy();activity = null;}private static void handleMessageArrived(String topic, String message, int messageId) {try {// JSONObject json = new JSONObject(message);// String typeName = json.getString("topic");LgqLogutil.e("返回数据====="+message);// switch (typeName) {//// }} catch (Exception e) {e.printStackTrace();}Log.e("))))))))))))", "topic:" + topic + ",message:" + message + ",messageId:" + messageId);}}

2、使用原生mqtt类实现mqtt推送以及上报数据

步骤、1——创建工具方法，调用即可

public class MainActivity extends AppCompatActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);// MqttProxy.init(this);//dlc的mqtt类使用// MqttMgr.get().publish();//dlc发送mqtt对象initMqtt();//原生mqtt类使用}private void initMqtt() {Looper.get().looper();}}
