`SamplesApp.Skia.netcoremobile` with Android+NativeAOT doesn't work right: some UI elements are clickable, but e.g. clicking the **▶️ Apply** button doesn't *do* anything. Update `App.xaml.cs` to enable *all* the logging categories when `NATIVE_AOT_EXTRA_LOGGING` is set, and update `SamplesApp.Skia.netcoremobile.csproj` to set `NATIVE_AOT_EXTRA_LOGGING` when `$(SkiaPublishAot)`=true. Additionally, unit test execution crashes on CI: F DEBUG : *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** F DEBUG : Build fingerprint:

`SamplesApp.Skia.netcoremobile` with Android+NativeAOT doesn't work right: some UI elements are clickable, but e.g. clicking the **▶️ Apply** button doesn't *do* anything. Update `App.xaml.cs` to enable *all* the logging categories when `NATIVE_AOT_EXTRA_LOGGING` is set, and update `SamplesApp.Skia.netcoremobile.csproj` to set `NATIVE_AOT_EXTRA_LOGGING` when `$(SkiaPublishAot)`=true. Additionally, unit test execution crashes on CI: F DEBUG : *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** F DEBUG : Build fingerprint:

What *appears* to be happening is that the CoreCLR & NativeAOT GC is collecting a managed instance while it's "native side" is still being used by native code: 1. Main thread: calls `CompositionHelper.Render()`, which sets `CompositionHelper._lastRenderedFrame`. 2. Render thread: reads `CompositionHelper._lastRenderedFrame` into `lastRenderedFrame`, eventually calls `canvas.DrawPicture(lastRenderedFrame.frame)`; 3. Render thread is suspended within native code, "within" `canvas.DrawPicture(lastRenderedFrame.frame)`. 4. GC thread comes along, sees that (`picture` parameter in `SkiaRenderHelper.RenderPicture()` / `lastRenderedFrame.frame` value within `CompositionTarget.Draw()`) is no longer referenced from managed code. 5. GC thread invokes `lastRenderedFrame.frame.Finalize()` 6. `SKPicture` (SkiaSharp) / `SkBigPicture` (Skia) is finalized. 7. Render thread resumes within native code, accesses the `SkBigPicture` *destroyed* in (6). 8. SIGSEGV A plausible solution to the above scenario is to extend the lifetime of `lastRenderedFrame.frame` until *after* `canvas.DrawPicture()` completes. This can be done via `GC.KeepAlive()`.
