Description of Bug:

Steps to re-create

  1. init MQTT Client. MqttAndroidClient mqttAndroidClient = new MqttAndroidClient(this, "mqtt://test.mosquitto.org:1883", MqttClient.generateClientId());

  2. Connect to the initiated client.

    try {                 
        IMqttToken iMqttToken = mqttAndroidClient.connect();
        iMqttToken.setActionCallback(this);
    } catch (MqttException e) {
        e.printStackTrace();
    }

  3. That's it. I am facing error in below callback method.

    @Override
public void onFailure(IMqttToken asyncActionToken, Throwable exception) {
    exception.printStackTrace();        
}

    printStackTrace already shown as below.

Has the problem been solved?

june5753 commented 3 years ago

You can do like this: Inside proguard.cfg file,add this -keep class org.eclipse.paho.client.mqttv3.internal. { ; } -keep class org.eclipse.paho.client.mqttv3.spi. { ; }

Good luck!

Connect to EMQ, please replace mqtt to tcp, like this:MqttAndroidClient mqttAndroidClient = new MqttAndroidClient(this, "tcp://test.mosquitto.org:1883", MqttClient.generateClientId()); Only 5 protocol supported: tcp/ssl/local/ws/wss
