Breakpoints is not hitting while debugging a .NET MAUI android application

I have been working on a MAUI android application and when debugging, the breakpoints is not hitting and the application enter in a break state. But for windows app it works well.
I think this is an issue with the .NET 6 Android Tooling in visual studio 2022. Is there any solutions for this problem ?

Here is a few steps I did to make things work with debugging MAUI Android apps. I was able to debug and get my regular exceptions and hit breakpoints after this.
Add this code to Android platform main activity OnCreate method
AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
Then this hander method in the same class
private void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{ System.Diagnostics.Debug.WriteLine(e.ToString());}
Reset Your Exceptions for CLR. Shortcut is (Ctrl+Alt+E).
Just double-click on the CLR Exceptions checkbox to reset.
Disable Debug Your Code Only in Options

I was also having problems debugging some projects. (Preview 17.1.0) The ones that were failing had the following project settings.
<PropertyGroup>
<TargetFrameworks>net6.0-ios;net6.0-android;net6.0-maccatalyst</TargetFrameworks> ...
Moving Android first fixed my problem
<PropertyGroup>
<TargetFrameworks>net6.0-android;net6.0-ios;net6.0-maccatalyst</TargetFrameworks> ...

I had the same problem and it is now working, try this:
Windows -> Settings -> Update & Security -> For Developers -> Developer Mode - On
Solution Properties -> Deploy - On
Visual Studio -> Tools -> Options -> Xml Hot Reaload -> Disable all
The you can just set your project has startup and run it.

Kotlin Debugging doesn't start in visual studio code

I'm new to Kotlin programming language. so... i have downloaded a few extensions such as Kotlin, Kotlin language,Kotlin Formatter, and when i press F5 it gives an ERROR...just one important question which is, should i use another IDE like intellij ?? because i don't really wan't to spend my time on fixing problems, also my computer can't handle android studio so it's between intellij and Vscode.
Error in the link below:
fun main(args: Array<String>) {
println("Hello World!")
}
that's the image of what i tried to debug + ERROR

I also had a hard time with setting up the debugger, and what worked for me was to checkout a template repository from https://github.com/fwcd/kotlin-quick-start and add the following debug configuration (.vscode/launch.json):
{
"version": "0.2.0",
"configurations": [
{
"type": "kotlin",
"request": "launch",
"name": "Kotlin Launch",
"projectRoot": "${workspaceFolder}",
"mainClass": "quick.start.AppKt"
}
]
}
As a bonus, Gradle is set up then, and one can build, run, and test the app out of the box.
Prerequisites
In VS Code I have installed the following plugins:
https://marketplace.visualstudio.com/items?itemName=fwcd.kotlin
https://marketplace.visualstudio.com/itemsitemName=mathiasfrohlich.Kotlin
https://marketplace.visualstudio.com/items?itemName=naco-siren.gradle-language
And I have installed the following packages locally:
snap install openjdk
snap install --classic kotlin

Of course you can debug your Kotlin code in Visual Studio Code. No need for IntelliJ or Android Studio.
To enable debugging in VS Code, you should install the Code Runner extension
https://marketplace.visualstudio.com/items?itemName=formulahendry.code-runner
and should have the Kotlin command-line compiler installed and configured in your system as well:
https://kotlinlang.org/docs/command-line.html
See the pages below for further, detailed infos:

https://medium.com/#agavatar/programming-with-kotlin-in-visual-studio-code-1d745d6b4ad1

Yes. You can proceed with intellJ. There is first priority i.e. Android Studio but as you mentioned it can not be handled, so you can use IntelliJ.
The advantage of Intelli J it provide by default support files and libraries for Kotlin Development so you don't need to install external extension.
he Kotlin plugin provides language support in IntelliJ IDEA and Android Studio.

null is not an object (evaluating 'RCTToastAndroid.SHORT')

I am attempting to convert my react-native project into an expo project, one small issue I've encountered is when I run the expo project I get an error as such
null is not an object (evaluating 'RCTToastAndroid.SHORT')
After doing some research online on how to fix this problem a user requested that a problem like this can simply be resolved by removing the Android part of RCTToastAndroid.SHORT this user stated that RCTToast is universally compatible with both iOS and Android. However when I do this I receive an error saying null is not an object (evaluating 'RCTToast.SHORT')
What can I do that will help ease the transition from my react-native project to an expo project?

All apps created with create-react-native-app, are compatible with Expo CLI without changes.
Ref link:- https://github.com/react-community/create-react-native-app/blob/master/CHANGELOG.md#upgrading-from-1140-to-201

only do like this
import {ToastAndroid}from 'react-native '
return ToastAndroid.show("some error msg", ToastAndroid.LONG);

I had the same exact problem.
Check to see if you've imported a library called 'react-native-simple-toast'. Remove it from your dependencies.
According to this issue:
this library has a custom native module for ios, and expo does not support that. This lib will not work with expo
it will only work with a bare React Native project.
If you do need to use Toasts
Here's a library that will work with Expo on both Android and iOS. The only downside is that it's pure Javascript.
You can use it like this:
import Toast from 'react-native-root-toast'
Toast.show('Your message here', {
duration: Toast.durations.SHORT,
position: Toast.positions.BOTTOM,
shadow: true,
animation: true
});

More than one file was found with OS independent path 'kotlin/reflect/reflect.kotlin_builtins' - Unity Project

I was trying to create Android build after exporting from Unity Project.
When I tried to export signed APK file, I got many errors and step by step , I have cleared all others.
But at present, get stuck on this one :
This is my Gradle file content :
I have tried Stackoverflow posts with similar problems. So I expect some other solution that work for me.

It seem it's an old post , but i m writing down here a solution it may help somebody else to solve this issue
In your app gradle (Kotlin DSL), add this block :
android {
//...
packagingOptions {
exclude("META-INF/kotlin-stdlib-common.kotlin_module")
exclude("META-INF/kotlin-stdlib-jdk7.kotlin_module")
exclude("META-INF/kotlin-stdlib-jdk8.kotlin_module")
exclude("META-INF/kotlin-stdlib.kotlin_module")
exclude("kotlin/annotation/annotation.kotlin_builtins")
exclude("kotlin/collections/collections.kotlin_builtins")
exclude("kotlin/coroutines/coroutines.kotlin_builtins")
exclude("kotlin/internal/internal.kotlin_builtins")
exclude("kotlin/kotlin.kotlin_builtins")
exclude("kotlin/ranges/ranges.kotlin_builtins")
exclude("kotlin/reflect/reflect.kotlin_builtins")
}
// ....
}
This will fix the build error.

Prism Xamarin.Forms monoandroid81 Add a reference to "MonoAndroid

I keep getting this error. (I'm using Android v8.1 and Prism default template)
Severity Code Description Project File Line Suppression State
Error Your project is not referencing the "MonoAndroid,Version=v8.1"
framework. Add a reference to "MonoAndroid,Version=v8.1" in the "frameworks"
section of your project.json, and then re-run NuGet restore.d#
PrismHelloWorld.Android
So I went into my project.assets.json and change the "monoandroid71" to "monoandroid81"
"originalTargetFrameworks": [
"monoandroid71"
...
"monoandroid71": {
"projectReferences": {
...
"frameworks": {
"monoandroid71": {
I also changed
"projectFileDependencyGroups": {
"MonoAndroid,Version=v7.1": [
and ...
"targets": {
"MonoAndroid,Version=v7.1": {
I hit save and rebuild and it works absolutely fine! The problem is something is editing the json file and turning it all back to 71 and 7.1. I am not sure what is doing it but I will hit built and see the error again, about me needing a reference to v8.1.
Has anyone encountered this issue before?

Go to Android project Options -> Application -> Compile using Android version: (Target framework) and choose Android 8.1 (Oreo). Try different options

I just had the same problem on MvvmCross with Xamarin and I did your solution (changing "monoandroid71" to "monoandroid81" and "v7.1" to "v8.1") but it reverts back after closing and reopening the solution. What I did was do the same thing and do a "Restore NuGet Packages" at the end.

got the same issue, and able to fix it using below option,
Change the target version and rebuild.

I had the same issue, what I did was just restarted VS, and its back to normal

I resolved it by:
Right click Android project => Properties => Application => Compile using Android version => Android 7.1
Clean and Build project => build success, and restart IDE.
Right click Android project => Properties => Application => Compile using Android version => Android 8.1
Clean and Build project => build success
File obj/project.assets.json updated to "MonoAndroid,Version=v8.1"
