i tried to publish message in loop to check load on broker. but only 20 messages pushed successfully when pushed 100 messages.

But working fine while sending with QOS = 0 ; i tried 2000 messages, that was working fine and delivered all messages.

I got this problem"Error:(org.eclipse.paho.client.mqttv3.persist.MqttDefaultFilePersistence$2) that doesn't come with an

Hi, first of all, thank you for creating this project. It's been so helpful to learn android while developing an MQTT app.

In ConnectionDetailsActivity.java I am trying to get the messages received from the MQTTCallbackHandler.java.

I believe the code for it resides in:
public void run() {

      connectionDetails.invalidateOptionsMenu();
      ((HistoryFragment) connectionDetails.sectionsPagerAdapter
          .getItem(0)).refresh();

      updateButtons();

    }

I created several logs to figure out where that data is, but I just have been unable to find it.

I tried:
Log.v(((HistoryFragment) connectionDetails.sectionsPagerAdapter
.getItem(0)).getArguments().toString(),"Arguments");

but am still unable to figure out where it is.

The goal is to listen to the subscribed message and update the status of a button on the screen.

In the MQTTCallbackHandler, I was able to identify that it is stored in args[0], but when it is passed to c.addAction(messageString) I don't know where it ends up for me to read in ConnectionDetailsActivity.java.

Thank you for your help!

Hi, sorry, maybe this is not the right section ... I tried your project on my Xiaomi note 5 mobile and it works very well. I recently carried out an IOT project with arduino for opening an electric gate via a WiFi relay card that uses an integrated ESP8266 programmed with arduino and controlled via the MQTT protocol. I also tried to make a small android app that uses the PAHO library and now I wanted to try to do something through my huawei watch 2 smartwatch with Wear OS 2.0. I tried to do something but even if there are no compilation errors (Android Studio), it doesn't want to know how to work. I wanted to ask you if you planned something for Wear OS ... Thanks a lot.

Hi, I'm trying to understand how I can connect in a secure way to a mosquitto broker, running on a Raspberry PI. I have configured mosquitto to ask for valid certificates, signed by my own CA. Now I'm looking in your Android Studio project and I have found the Advanced activity in which it's possible to set the SSL flag and to insert a file path. Which file does it ask for? I'm in possess of .crt and .key files for the client, but I think the application needs something different.
Thank you in advance for your help!
