Looking at the logcat output, and the output is "interesting". PID 4955 is the relevant process; only PID 4955 output: What looks particularly "interesting" is: I don't know where this message is coming from; I don't see it in xamarin-android or in dotnet/runtime. |

`dotnet new android` apps would crash on startup when built with

`java_interop_jvm_list` should *never* be called on Android, it is the
result of `new AndroidRuntime()` having not been called yet?
The problem being that the static `Android.App.Application.cctor` was
somehow running *before* `JNIEnv.Initialize()` was complete? And this
only happens with LLVM?
Reviewing the code:
[UnmanagedCallersOnly]
internal static unsafe void Initialize (JnienvInitializeArgs* args)
{
//...
SynchronizationContext.SetSynchronizationContext (Android.App.Application.SynchronizationContext);
}
We do indeed access `Android.App.Application`...
To fix this, we can move this to a new method decorated with
`MethodImplOptions.NoInlining`. Apps built with LLVM now launch for
me.
We can also enable the LLVM `Mono.Android-Tests` again.

I kept these disabled because of: dotnet/runtime#73304
I think we should merge this with the tests disabled, because it does get things further.

Since 0084162, this Condition wasn't actually doing anything. We weren't passing in RunAOTCompilation=true because that is the default value for Release builds.
InetAccess seems to crash the tests when EnableLLVM=true, however... So let's keep the condition for that case.

Can you please also open an issue for the InetAccess test crashes with LLVM enabled?

The designer tests should be getting fixed by: #7227 And going to ignore these, unrelated:
Going to merge, with a decent commit message shortly. |

Is it necessary to disable profiled AOT?

This one was: dotnet/runtime#73003
Using Profiled AOT and LLVM at the same time can hit:

However, we can't really enable the LLVM `Mono.Android-Tests` quite
yet. Read on!
