Re: [paho-dev] Support for Mqtt 5.0

Thanks Ian. Really appreciate your effort on this. Will look forward for updates on this.

I need to migrate my current application to support MQTT 5. This is .NET C# based application.

Thanks & Regards,
Seena L.S.

Hello,

I'm currently working on MQTT V5 support for the Java client, have a PR for the Python client which I have to get back to, and then the JavaScript and embedded C clients.? (I completed the C client last year).

The C++ and Rust client rely on the C client, so they will pick up V5 support too.

There is no-one currently actively maintaining the .Net client, so if it ends up that I'm the only candidate for adding V5 support, then it will take a while, behind all the others!? And it might not happen at all.? 
We have asked for volunteers for maintainers, but to no avail so far.

Dear all,

I am using the current Paho Android Service version "
org.eclipse.paho:org.eclipse.paho.android.service:1.0.2"
in my gradle.

I have declared compileSdkVersion 28 and targetSdkVersion 28 in my gradle also.

When I run the application on Android 9.0 (simulator and device) I receive the following exception:
"Bad notification for startForeground:  java.lang.RuntimeException: invalid channel for service notification:  Notification(channel=null pri=0 contentView=null vibrate=null sound=null defaults=0x0 flags=0x40
color=0x00000000 " and the application crashes.

However, if I run the same application on Android 8.1 (emulator and device), I do not receive this exception and the application connects to MQTT server properly.

Moreover, I noticed that If I have declared compileSdkVersion 26 and targetSdkVersion
26 in my gradle, the application works properly on both Android OS 81. and 9.0.

So, I was wondering if the paho version 1.0.2 is compatible with Android OS 9.0.

Regards,
Kostas

Hi, Kostas.
Our team use paho.android.service 1.1.1 version and our project works fine on both Android N and and Android O with project target setting 28. Try the latest stable version. It may fix the problem.

Regards,
Alan
