Android: new cil-strip feature causes app crashes #88538
Description
Description
This was originally implemented in:
- [Mono] Add the capability of trimming IL code of individual methods #86722
- [Xamarin.Android.Build.Tasks] implement $(AndroidStripILAfterAOT) android#8172
But the app crashes at runtime, log snippet with mono --trace on:

The method in question, looks like it is stripped as expected:
I also get the log message:
07-07 08:33:25.712 18759 18759 D Mono : AOT: FOUND method Android.Runtime.JNIEnvInit:Initialize (Android.Runtime.JNIEnvInit/JnienvInitializeArgs*) [0x74d4760990 - 0x74d4760d10 0x74d476a970]
Reproduction Steps
- Build the branch of [Xamarin.Android.Build.Tasks] implement $(AndroidStripILAfterAOT) android#8172
- (Or you could potentially edit the
.targetsfiles locally)
- (Or you could potentially edit the
dotnet new android- Build & run the app with IL-stripping enabled:
dotnet build -c Release -p:AndroidStripIL=true -t:Run
Expected behavior
A dotnet new android app runs.
Actual behavior
dotnet new android app appears to crash at the first managed method that was stripped away.
Regression?
No, this is a new feature.
Known Workarounds
Don't use -p:AndroidStripIL=true, as this is the new feature.
Configuration
.NET SDK 8.0.100-preview.7.23330.16
