Loading image from Resources causes native crash in Release

According to Microsoft, this is the correct way to load an image

Assembly assembly = GetType().GetTypeInfo().Assembly;
using Stream stream = assembly.GetManifestResourceStream("Ringotan.KanjiControl.Resources.next_arrow.png");
_arrowImage = PlatformImage.FromStream(stream);

This works perfectly in Debug. However, in Release it causes the entire app to crash with the native exception

[libc.so] __memcpy_aarch64_simd

    SIGSEGV

backtrace:
  #00  pc 0x0000000000058158  /apex/com.android.runtime/lib64/bionic/libc.so (__memcpy_aarch64_simd+280)

because it's a native crash, there's no way to catch it or handle it gracefully.

Is there any way to fix this? If not, is there a better way to load an IImage?

Notes:

Solution

  • I was able to work around (but not fix) the issue by not loading the image from a separate assembly, and not loading the image using GetManifestResourceStream. I'm not sure which of those two are necessary.

    1. Moved Resources/next_arrow.png from class library to main app project (under Resources/Images/next_arrow.png). The Build Action should be "MauiAsset"
    2. Added Android-specific code which calls Application.Context.Assets.Open("Resources/Images/next_arrow.png").
      (I believe the iOS equivalent would be something like File.Open( Path.Combine(NSBundle.MainBundle.ResourcePath, "Resources/Images/next_arrow.png")), but don't quote me on that because I started the iOS port yet)
    3. Called the Android-specific code from the class library using dependency injection.
