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

Question

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 ?

Answer 1

I had the same problem and it is now working, try this:

1. Windows -> Settings -> Update & Security -> For Developers -> Developer Mode - On

2. Solution Properties -> Deploy - On

3. Visual Studio -> Tools -> Options -> Xml Hot Reaload -> Disable all

4. The you can just set your project has startup and run it.

Answer 2

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> ...

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.

1. 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());}

2. Reset Your Exceptions for CLR. Shortcut is (Ctrl+Alt+E).

   Just double-click on the CLR Exceptions checkbox to reset.

3. Disable Debug Your Code Only in Options
