simplechat | small one-room chat | Runtime Evironment library

I am writing an android app with firebase and kotlin. Now I created a kotlin class that extends Service class.

The problem is, after start service if I close the app it crashed!

If I write same code with java all working fine! I can't understand why it crashed when I use kotlin?

Look my code bellow.

myService.kt

I have a simple Meteor app just the basic meteor create test. I want to be able to route traffic to the "/" directory to a template.

I want to be able to route data from a facebook web-hook to a simple js response.

My issue is that when I fire the web-hook URL using postman it returns HTML and not my response.

I've tried many different options for other posts I have read but now have the most basic version to just get it working.

Here is the code I've used

main.html

I try to run the tutorial from Anthony Chu. https://www.youtube.com/watch?v=4d0wor7uAgQ

He implemented a "SimpleChat-Application" with Azure CosmosDB, Azure Functions and SignalR. Where you can send messages between Clients in Realtime. I tried different settings and version but i can´t make it work.

Source Code in my "index.html": (JavaScript)

I set a php/javascript chat for my site, the problem is that I want to show only the last 5 messages, and then the older ones after 5 must disappear. These messages are entered in the pre . How can this be done? This is all the code I am using

How can I get an RpcDispatcher to remotely invoke the methods of a different class? The examples I've seen online all seem to demonstrate how it works when they're all instances of the same class. E.g. this one from the JGroups manual works fine for me because you just start multiple instances of RpcDispatcherTest and they all contain the print(int) method.

So how excatly could I get said RpcDispatcherTest to invoke from another, separate JGroups class, e.g. something like the SimpleChat example (also from the JGroups manual).

I've tried asking RpcDispatcherTest to connect to the same channel as SimpleChat: channel.connect("ChatCluster");. They seem to register eachother, and you can see the updated view with the multiple classes running, but I've failed to get the RpcDispatcherTest to actually invoke a method from SimpleChat, even if I copy the exact same print(int) method into it.

This Android code for MainActivity but its not working in my case but from where i copied it working fine there so please tell where i messed up.

I am new to Android development so please help me.
