            MQTT Android client not connecting to broker
            Asked 2020-Nov-01 at 19:06

            I'm playing around with MQTT and Android, but I can't seem to connect the client to the broker. This is how the code looks like:



            Answered 2020-Nov-01 at 19:06

            Turns out the MqttService needs to be declared in the manifest to be able to bind to the Paho Android Service correctly:

            NoClassDefFoundError -> How can I make this kotlin code work to implement a MQTT connection?
            Asked 2020-Oct-02 at 10:33

            I found this code on this site, it implements an MQTT client for Android, and it's written in Kotlin.

            I have really few experience with this language, so I don't understand how to make it work. I copied it into my MainActivity.kt file and I'm calling connect(this) from onCreate function:



            Answered 2020-Sep-30 at 11:23

            When running within an Activity, you can provide this as the Context (as Activity is a Context class). When running elsewhere, you'd need to see where to obtain the Context from, which is eg. this.getContext() within a Fragment (assuming the Fragment is attached to an Activity). In this case, even the (non-themed) ApplicationContext should suffice.



            Create a callback function with another callback inside
            Asked 2020-Jul-30 at 12:55

            My apologies for the bad title, I'm fairly new to callbacks and I'm not sure how to explain what I'm trying to achieve.

            I have a class called MyClass that has a function connectToService inside of it.

            The function connectToService does some calculations and then calls a function with a callback, like this:

            Why my android app is giving "your app keeps stopping" while connecting to mqtt broker
            Asked 2020-Apr-07 at 13:07

The moment I click the connect button, I get the message your android app keeps stopping. here is my code. I have uploaded necessary repositories and dependency and also permissions

            QoS=1 with MqttAsyncClient subscription miss messages
            Asked 2020-Feb-26 at 20:20

            I have foreground service acting as MQTT client. I'm using MqttAsyncClient mqttClient for this purpose.
            I'm using QoS=1 on subscribe to topic:



            Answered 2020-Feb-26 at 20:20

            You are setting cleansession to true (options.setCleanSession(true)); from the docs for setCleanSession:

            If set to true the client and server will not maintain state across restarts of the client, the server or the connection. This means

            • Message delivery to the specified QOS cannot be maintained if the client, server or connection are restarted
            • The server will treat a subscription as non-durable

            I think that the mqtt specs state this more clearly:

            If CleanSession is set to 1, the Client and Server MUST discard any previous Session and start a new one. This Session lasts as long as the Network Connection. State data associated with this Session MUST NOT be reused in any subsequent Session

            So when your application looses the connection the session is discarded and new messages will not be queued up for delivery. In addition unless you resubscribe when the connection comes back up you will not receive any additional messages.

            However be aware that if you set cleansession to false then any new messages received while your client is offline will be queued for delivery (subject to the configuration of the broker) and this might not be what you want to happen if the client could be offline for a long time.



            Can't pass data to another fragment in Android (Kotlin)
            Asked 2020-Jan-25 at 10:25

            I've got a problem. I'm making an application for Android of the client of MQTT and I need to use the same parameters for MqttAndroidClient() method in different fragments. I've already tried to pass them in the bundle, with intent putExtra(), making objects of the class. The bundle and putExtra send the data to another fragment, it shows in the debug mode, but in the target fragment I get nulls. When I'm trying to receive the value instantiating the first fragment, it sends me the lateinit variable without any value in it. I have no ideas what can I do more. I thought about using setters and getters to get it, but I'm not sure that is the solution.

            First fragment where I send the data:




            Answered 2020-Jan-25 at 10:25

            First of all to create a fragment you should have a newInstance method and this method should except the parameters that you want to pass to the fragment, in your case SubscriberFragment should have following function in companion object



            MqttConnectOptions members not recogized by Android Studio 3.1.1
            Asked 2019-Nov-21 at 02:14

            I am writing a straightforward mqtt client. For some strange reason Android studio 3.1.1 can't resolve any member function of MqttConnectOptions.

            None of the members functions of MqttConnectOptions are recognized by the compiler.

            All the examples I can find on the web use the MqttConnectOptions members. I'm baffled!

            What simple thing am I missing?



            Answered 2018-Apr-29 at 02:25

            It was just a rookie mistake, I was trying to set the options outside the code section of the main activity.

            Never mind.
