is there a way to catch global application exceptions?

Question

Is it possible to catch all the unhandled exceptions in a centralized place? i.e. let's say that the game could through server connection exceptions in several places, I want them to be caught from an unique place, for example to show a message box.

You can use Application.RegisterLogCallback to get everything that goes into the unity log - it gives you the type, the stack trace and the logging string of exceptions and, of course, a bunch of other things - would that help you?

yes I thought about that, but I am not sure it is a good idea. I mean if I cannot use catch, I will not either use throw then. I could implement something on my own (like a messaging system that works in a similar way)

Yeah, understood - thought it was worth pointing out.

I mark it as correct, because eventually it was a correct answer

This was exactly what I was looking for.

It is deprecated however, the new callback is "Application.log$$anonymous$$essageReceived".

So you would do:

 private void Awake(){
     Application.log$$anonymous$$essageReceived += handleUnityLog;
 }
 
 // then
 
 private void handleUnityLog(string logString, string stackTrace, LogType type) {
     // do stuff
 }

That sounds like a bad idea.

Nevertheless, these pages discuss some options:

That Stack Overflow thread is not primarily discussing the Mono runtime, so may not apply.

oh thanks for the answer...yeah in c# it is easy, but I was wondering how to do it in the Unity Environment. In a standard c# application I have the concept of mainform, which I do not have in Unity.

 using UnityEngine;
 using System;
 
 
 public class test : MonoBehaviour {
     public string output = "";
     public string stack = "";
     void OnEnable() {
         Application.RegisterLogCallback(HandleLog);
     }
     void OnDisable() {
         Application.RegisterLogCallback(null);
     }
     void HandleLog(string logString, string stackTrace, LogType type) {
         output = logString;
         stack = stackTrace;
     }
 }
