QUESTION
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:
...ANSWER
Answered 2020-Sep-30 at 11:23When 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.
QUESTION
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:

QUESTION
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:
ANSWER
Answered 2020-Feb-26 at 20:20You 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.
QUESTION
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:
ConnectFragment.kt
...ANSWER
Answered 2020-Jan-25 at 10:25First 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
QUESTION
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?
...ANSWER
Answered 2018-Apr-29 at 02:25It was just a rookie mistake, I was trying to set the options outside the code section of the main activity.
Never mind.
