Usage

Before:

final MqttAsyncClient client = new MqttAsyncClient(url, id, persistence)

client.setCallback(new MqttCallback() { // message
    @Override
    public void connectionLost(@Nullable final Throwable e) {
        if (e != null) {
            e.printStackTrace();
        } else {
            (new RuntimeException("Connection Lost")).printStackTrace();
        }
    }

    @Override
    public void messageArrived(@NonNull final String topic,
                               @NonNull final MqttMessage message)
            throws Exception {
         Gson.parse(message.getPayload(), Telemetry.class)
    }

    @Override
    public void deliveryComplete(IMqttDeliveryToken token) {
        // nothing
    }
});

MqttConnectOptions options = new MqttConnectOptions();
options.setCleanSession(true);
client.connect(options, null, new IMqttActionListener() {
    @Override
    public void onSuccess(@NonNull final IMqttToken token) {
        client.subscribe(topic, 0, null, new IMqttActionListener() {
            @Override
            public void onSuccess(@NonNull IMqttToken token) {
                // nothing
            }

            @Override
            public void onFailure(@NonNull final IMqttToken token,
                                  @Nullable final Throwable e) {
                if (e != null) {
                    e.printStackTrace();
                } else {
                    (new RuntimeException("Connection Lost")).printStackTrace();
                }
            }
        }, new IMqttMessageListener() {
            @Override
            public void messageArrived(String topic, MqttMessage message)
                    throws Exception {
                // nothing
            }
        });
    }

    @Override
    public void onFailure(@NonNull final IMqttToken token,
                          @Nullable final Throwable e) {
        if (e != null) {
            e.printStackTrace();
        } else {
            (new RuntimeException("Connection Lost")).printStackTrace();
        }
    }
});

After:

For pure Java:

  RxMqtt.message(RxMqtt.client("tcp://test.mosquitto.org:1883"), "#"))
  .subscribe(System.out::println);

For Android:

RxMqtt.message(RxMqtt.client(context, "tcp://test.mosquitto.org:1883"), "#")
  .subscribe(System.out::println);
