Does this need to be documented anywhere? nvm that! |

@vargaz these options are a little bit difficult for embedders to use - Here's how XA does it now: https://github.com/xamarin/xamarin-android/blob/169838082a55f8a280d4179ca3a12f852ef6002c/src/monodroid/jni/monodroid-glue.cc#L835 @steveisok is there some way to pass options to our Android template? It would be nice if we could modify one of the functional tests to use this https://github.com/dotnet/runtime/tree/main/src/tests/FunctionalTests/Android/Device_Emulator |
We'd have to tweak a few things, but it shouldn't be too difficult. |
Will fix that. I think it is parsed when parsing MONO_ENV_OPTIONS. |
|
Also, options.h could become part of the embedding api in the future if the api looks ok. |
… referenced by AOT images lazily. Note that this requires the assemblies used at AOT time to exactly match the assemblies loaded at runtime, otherwise the runtime will abort when it loads the mismatching reference.

There was a problem hiding this comment.
Should we make the default true for HOST_ANDROID, HOST_WASM, HOST_DARWIN && !HOST_OSX?

I think platforms should set it themselves.

Or maybe we can set it in the runtime startup code.

Have we tried using this on Maui Android and gotten any before/after startup perf numbers? |

Fixes: dotnet#6935 Context: dotnet/runtime#67024 Add support for enabling lazy loading of AOTd assemblies and their associated shared libraries, when targetting .NET6+. The feature is enabled by default when AOT is enabled for `Release` builds and can be disabled by setting the new `$(AndroidAotEnableLazyLoad)` MSBuild property to `false`.

… referenced by AOT images lazily.
Note that if this is enabled, and a referenced assembly is not found or its not
the exact version used to AOT the referencing assembly, the runtime will abort
because these kinds of errors can only be handled when loading the AOT image,
not later.
