[rokmeglicbit]

How to know why the app is crashing? It works If I run it as active debugging session in Visual Studio, but it does not work after I stop this debugging session and I run the app without active debugging session from the phone (app click).
All latest version (10.0.90).

How to get more information why this happen?

I watched your video, @jfversluis , and got excited, but it doesn't work for me. 🙂

[jfversluis]

@rokmeglicbit thanks for sharing! Is this with your own project? Or just a file > new MAUI project? If it's your own project, are you able to share it? So if I understand correctly if you run from Visual Studio with debugging it works, but not when you then stop the debugging session and launch it again? What Android version? Is this on an emulator or physical device?

@jonathanpeppers @simonrozsival

[jonathanpeppers]

If this is .NET 10, you can do:

# enable verbose logging for Mono runtime
adb shell setprop debug.mono.log default,debugger,assembly,timing=bare,mono_log_level=debug,mono_log_mask=all
# clear the current log
adb logcat -c
# make the app crash
# save the log
adb logcat -d > log.txt

If the C# stacktrace is in dotnet/maui, it can be a new issue here. Otherwise, you can file a new issue at dotnet/android, or just share here and we can look.

[rokmeglicbit]

@jfversluis yes, correct. Android, Google Pixel 8 Pro, physical device, client project.

<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'android'">26.0</SupportedOSPlatformVersion>
<TargetPlatformMinVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'android'">36.0</TargetPlatformMinVersion>

We updated all the NuGet and now I can not reproduce it, I do not know why.
Thank you @jonathanpeppers . I will report back If I can reproduce it again.

Lately I have sometimes wierd problems, like ObjCRuntime.RuntimeException, or Cannot access disposed object, but when I try to reproduce them, I can not :)

[rokmeglicbit]

Is this related? It does not crash the app, just a warning.

I can not reproduce on Android now, but it happens on iOs.
If I remove SourceGen it works normally / nothing else changed.

This looks like an unhandled managed exception rather than a native crash. Mono calls Environment.FailFast while ShellSectionRootRenderer.ViewDidLoad() is creating the first Shell page, but the crash report does not include the original exception.

Could you share the device-console/logcat output immediately before SIGABRT? That should contain the managed exception and identify the generated XAML or binding that failed. The VibrationEffect$Composed warning appears unrelated.

Since disabling MauiXamlInflator=SourceGen avoids the crash, a small reproduction project would also be very helpful.
