[paho-dev] automatically subscribe after a successful connection

["陈健" <772929989@xxxxxx>]

In order to automatically subscribe after a successful connection. I write a broadcastreceiver  to receive  the intents  of  "MqttService.callbackToActivity.v0". ‍‍I think this should be easy.‍

-------------------------------------------------------------

private void registerReceiverMqtt() {

broadcastReceiver = new BroadcastReceiver() {

static final String TAG = "MqttService";

static final String CALLBACK_ACTION = TAG + ".callbackAction";

static final String CONNECT_ACTION = "connect";

static final String CALLBACK_STATUS = TAG + ".callbackStatus";

@Override

public void onReceive(Context context, Intent intent) {

String action="">

Bundle data = "">

Status status= (Status) data.getSerializable(CALLBACK_STATUS);

if (CONNECT_ACTION.equals(action)) {

if(status ==Status.OK){

try {

mqttClient.subscribe(Constants.TOPIC, 1);

} catch (MqttSecurityException e) {

e.printStackTrace();

} catch (MqttException e) {

e.printStackTrace();

}

}

}

}};

IntentFilter filter = new IntentFilter();

String  fileName="MqttService.callbackToActivity.v0";

filter.addAction(fileName );

registerReceiver(broadcastReceiver, filter);

}‍
