Notification is not removing when we set setForegroundService in mqtt client

[Monika-Paliwal]

We have added the notification in mqtt for show the notification in notification bar but when we logout the app the notification bar still showing.
We have used below mentioned code.
mqttClient!!.setForegroundService(notification.build(), notificationId)

And also used code for cancel notification
val notificationManager = context getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager notificationManager.cancel(notificationId)

Can you please provide the solution for stop the foreground service.

[hannesa2]

I guess you have to do something like this https://stackoverflow.com/a/35721582/1079990

[Monika-Paliwal]

No, We are using below mentioned code in kotlin class so need a solution for stop mqttClient service
mqttClient!!.setForegroundService(notification.build(),notificationId)`
if we are using this.stopForeground(true) then it will show create member function.

Sorry for the late response.
Please use https://github.com/hannesa2/paho.mqtt.android/releases/tag/3.6.0-beta7 and please tell me, how it works after several connect/disconnect. I didn't tested this.

still have issue of this , removing notification after disconnect

[NinaTietje]

Hey Hannes, I searched for an already working solution to remove the foreground notification for the 3.x versions.
So I tested the 3.6.0beta7 branch with the extendedSample. Showing and removing the notification via the connection switch is working fine, but it doesn't really reconnect and messages can't be received. Only after an app kill and restart the connect via the connection switch would work (but only for the first time after the app started).
I also tested adding the changes from here #560 to 3.6.3. Here the reconnect works all the time, all messages are received. Using the connection switch the notification will be removed but not shown again except when the connection has been terminated AND the app was killed before. Just killing the app doesn' t remove the notification.
Maybe you have an idea how to improve #560

[hannesa2]

Hi, you mean we should apply #560 on 3.x branch as well ?
Not sure if it will work, when we do something on onTerminate() of application.

To be honest, I would put afford to 4.x. May I ask you, why you still using 3.x ?

[NinaTietje]

Yes, that's what I meant. But just the changes from #560 would not be enough to work completely fine.

Sure, I rely on receiving messages and displaying notifications while the device is asleep and currently this is only working well on the 3.x versions. On the 4.x versions (with started foreground service) the connection will be lost after a few minutes and it won't reconnect while the device is asleep. (Also tested with the extendedSample from 4.2.4)

[NinaTietje]

Found out that #560 already works fine (only in the extendedSample something seemed to be missing).
I would be very grateful if you could add a release for 3.x with it or just a beta version. I know at some point the foreground service will become obsolete and I still want to find out why the workmanager solution for 4.x doesn't work completely.

[hannesa2]

Here is the release https://github.com/hannesa2/paho.mqtt.android/releases/tag/3.6.4

I still want to find out why the workmanager solution for 4.x doesn't work completely.

I'm looking forward for your help

@NinaTietje
I did a 4.x test drive on a real device and lock device. But I'm not sure if device falls asleep during USB debugging.
I never see a lost connection and for me it looks not wrong

[hannesa2]

Without debugging I see with built in logcat view

this error
