11.1.0-beta1 breaks app near startup on Android Emulator

[AArnott]

Describe the bug

Upgrading from 11.0.7 to 11.1.0-beta1 causes my app to crash. The last lines in the debug output window are:

[monodroid-assembly] open_from_bundles: failed to load assembly Nerdbank.Bitcoin.dll

To Reproduce

Expected behavior

Avalonia version

11.1.0-beta1

OS

No response

Additional context

No response

Are there any useful stacktraces in logcat maybe? Also, you can try to listen for AndroidEnvironment.UnhandledExceptionRaiser (android specific) or Dispatcher.UnhandledExceptions (avalonia specific).

[AArnott]

Neither of the event handlers you suggested I add were invoked for this crash. But thanks for them anyway as I'm sure they'll be useful to keep an eye on.

Here is my logcat log: logcat.txt You may find logs relevant to my app by searching for nerdbank.

Here are some potentially interesting ones, though more logs follow it, so I don't know if this represents the actual crash:

You can request paid support in this case, so we can handle closed source also. Otherwise try to create a minimal sample

[redradist]

I've faced the same issue with Android Emulator ... @maxkatz6 For me issue happens for Android SDK API 35, all older version like API 32, 33, 34 looks like works fine

[AArnott]

I'm on 11.1.0-rc2 now and it works fine for me. But I'm using Android API 34. Feel free to close, or keep open for @redradist's sake.

[timunie]

@redradist which Avalonia version do you use?
