Bottom Tabs throws a Java.Lang.RuntimeException: 'Font asset not found sans-serif' as a FirstChanceException #13601

Open mfeingol opened 3 years ago

mfeingol commented 3 years ago

Steps to Reproduce

  1. Build, deploy app, start debugging
  2. Observe 12 Java.Lang.RuntimeExceptions at startup
  3. Hit F5 to continue

I wasn't able to reproduce this in a fresh Xamarin Forms Android app, so I can give you access to build and run my app if needed.

There are two issues here:

  1. Disabling first-chance handling of Java.Lang.RuntimeException in Visual Studio requires disabling all exceptions in Exception Settings. Disabling just Java.Lang.RuntimeException does not work: the exceptions mentioned below are still raised in the debugger. This happens every time I run my app.

  2. The exception is thrown 12 times at startup, even though my app doesn't reference a sans-serif font at all. In order:

Java.Lang.RuntimeException: 'Font asset not found sans-serif'
Java.Lang.RuntimeException: 'Font asset not found Fonts/sans-serif'
Java.Lang.RuntimeException: 'Font asset not found fonts/sans-serif'
Java.Lang.RuntimeException: 'Font asset not found sans-serif'
Java.Lang.RuntimeException: 'Font asset not found Fonts/sans-serif'
Java.Lang.RuntimeException: 'Font asset not found fonts/sans-serif'

... with the following stack trace:

Expected Behavior

No exceptions are thrown at startup. And if handled exceptions have to be thrown, then VS should allow me to silence them without disabling all other exception handling.

Actual Behavior

12 exceptions are thrown at startup. They can't be silenced with disabling all exception handling.

jpobst commented 3 years ago

This looks like it's probably in the Xamarin Forms stack, transferring there.

Feel free to send it back if it's a Xamarin.Android issue.

mfeingol commented 3 years ago

@jpobst: thanks! Any thoughts on the first issue, the fact that it's not possible to disable first-chance Java.Lang.RuntimeExceptions without disabling all exceptions?

jpobst commented 3 years ago

Looking at the place where it is thrown, it definitely isn't thrown like I would expect. My random guess is that this mechanism of throwing has an issue with first chance exceptions?

public static unsafe JniObjectReference CallStaticObjectMethod (JniObjectReference type, JniMethodInfo method)
{
    if (!type.IsValid)
        throw new ArgumentException ("Handle must be valid.", "type");
    if (method == null)
        throw new ArgumentNullException ("method");
    if (!method.IsValid)
        throw new ArgumentException ("Handle value is not valid.", "method");
    System.Diagnostics.Debug.Assert (method.IsStatic);

    var __info = JniEnvironment.CurrentInfo;
    var tmp = __info.Invoker.CallStaticObjectMethod (__info.EnvironmentPointer, type.SafeHandle, method.ID);

    Exception __e = JniEnvironment.GetExceptionForLastThrowable ();
    if (__e != null)
        ExceptionDispatchInfo.Capture (__e).Throw ();   // <-- Thrown here, instead of `throw new RuntimeException`

    JniEnvironment.LogCreateLocalRef (tmp);
    return new JniObjectReference (tmp, JniObjectReferenceType.Local);
}

I'll ask around and see if anyone knows more.

Possibly related?

The short version is that exception handling is a bit "weird", primarily because when an exception is thrown, it's not really possible for Xamarin.Android to participate in the "normal" two-pass "is this exception handled" algorithm that the debugger expects. Thus, either all exceptions are "not handled" -- which is why you're seeing so many first chance exceptions in the IDE -- or all exceptions are handled, which means there would never be a first-chance exception.

I have no good suggestions for workarounds. I can only hope that eventually we'll be able to make things work "better."

Thanks, @jonpryor.

Oddly those links gave me a workaround hint: disable System.Exception in Exception Settings and the debugger no longer breaks when the Java.Lang.Runtime exception is thrown. Kind of odd, but there you go.

So I guess the remaining question is... what is my app, which has nothing to do with sans-serif, doing to trigger these exceptions during Xamarin.Forms bootup?

jsuarezruiz commented 3 years ago

@mfeingol Could you attach a sample where reproduce your same exception?

mfeingol commented 3 years ago

@jsuarezruiz: I can't, but I can give you access to my project on GitHub if you want to reproduce it there.

mfeingol commented 3 years ago

@jsuarezruiz: let me know.

Redth commented 3 years ago

Please, if you can give @jsuarezruiz access to the repo and let us know here when you do, thanks.

mfeingol commented 3 years ago

@Redth, @jsuarezruiz: invite sent.

@mfeingol I'm guessing you have a shell app

Shell by default uses "sans-serif" for the text on the BottomNav I don't have any historical context as to why it does or if that's correct though :-/

mfeingol commented 3 years ago

@PureWeen: interesting guess, but no, I'm not using shell. I'm using FlyoutPage because I need to use tabs in inner navigation pages.

PureWeen commented 3 years ago

It looks like it's anything that uses bottom tabs

https://github.com/xamarin/Xamarin.Forms/blob/80a4dbfb1cd897f478c38d0aafa6a5d67940d2f3/Xamarin.Forms.Platform.Android/Renderers/BottomNavigationViewUtils.cs#L176

Shell and BottomTabs use the same implementation on android

mfeingol commented 3 years ago

I'm using TabbedPage, for what it's worth. But using tabs at the top, not the bottom.

Bumping this issue.

rysbilinski commented 2 years ago

Also bumping. Workaround of disabling System.Exception works

EmilAlipiev commented 1 year ago

is that error still available in Maui? XF latest version at least has it

mfeingol commented 1 year ago

I haven't seen it in Maui. XF definitely still has it.
