Thank you @AIlll for reporting to us. Can you post a code snippet if possible?

@kvasukib

// MQTT Client
mqttManager = new AWSIotMqttManager(clientId, CUSTOMER_SPECIFIC_ENDPOINT);

// Set keepalive to 10 seconds.  Will recognize disconnects more quickly but will also send
// MQTT pings every 10 seconds.
mqttManager.setKeepAlive(10);
// Set Last Will and Testament for MQTT.  On an unclean disconnect (loss of connection)
// AWS IoT will publish this message to alert other clients.
 AWSIotMqttLastWillAndTestament lwt = new AWSIotMqttLastWillAndTestament(TOPIC_LWT,"Android client lost connection", AWSIotMqttQos.QOS0);
mqttManager.setMqttLastWillAndTestament(lwt);

// load keystore from file into memory to pass on connection
clientKeyStore = AWSIotKeystoreHelper.getIotKeystore(CERTIFICATE_ID,  KEYSTORE_PATH, KEYSTORE_NAME, KEYSTORE_PASSWORD);

 mAwsIotMqttManager.connect(clientKeyStore, mqttClientStatusCallback);

thanks for you're reply. but the code which i written is very similar with your example code

@AIlll Thank you for the reply.

1. Do you experience reconnect for every connect? Or does this happen only for certain connect calls?
2. Are there issues with network connectivity during the time you are trying to connect?
3. What type of network are you on?

@kvasukib

1. not every connect , but it happened repeatedly.
2. maybe for sometimes
3. wifi

It seems that I have solved the problem , but I am not sure what the problem is.

mAwsIotMqttManager.connect(clientKeyStore, new AWSIotMqttClientStatusCallback() {
                  @Override
                  public void onStatusChanged(AWSIotMqttClientStatus status, Throwable throwable) {
                       if (status == AWSIotMqttClientStatusCallback.AWSIotMqttClientStatus.Connected) {
                          throw new NullPointerException("When the status is connected,Exception will cause reconnect");
                        }
                   }
               });
