AndroidStripILAfterAOT causing "InvalidProgramException: Invalid IL code in Xunit.Assert:True(bool)"

[tranb3r]

Android application type

.NET Android (net7.0-android, net8.0-android, etc.)

Affected platform version

VS 2022 17.8.5

Description

When setting AndroidStripILAfterAOT=true in a test app, some tests are failing the first time we run them, but then they'll pass if we run them again.
The error is 100% reproducible when starting the app again.
Here is the error: InvalidProgramException: Invalid IL code in Xunit.Assert:True(bool): method body is empty.
No issue in Debug. No issue when removing AndroidStripILAfterAOT=true.
This is similar to #104156, but no BroadcastReceiver is involved here.

Steps to Reproduce

1. Open repro in visual studio.
2. Run app in Release on android emulator.
3. Run all tests: one of the test fails.
4. Run all tests again: both tests succeed.

Did you find any workaround?

Remove AndroidStripILAfterAOT=true.

@fanyang-mono & @vitek-karas could you take a look into this? Thanks! :)

[fanyang-mono]

I will work on this.

Any update?

Hi @tranb3r, sorry for the delay. I tried building and running the app that you linked in this issue. I tried with .NET8 sdk and .NET8 service 1 sdk. I was not able to reproduce with either of them. Here are my steps:

• Get .NET8 sdk
• Install maui workload
• Add <AndroidStripILAfterAOT>true</AndroidStripILAfterAOT> in Issues/MauiAppXunitInvalidILCode/MauiAppXunitInvalidILCode/MauiAppXunitInvalidILCode.csproj
• Open an Android arm64 emulator
• Build and runt the app from Issues/MauiAppXunitInvalidILCode/MauiAppXunitInvalidILCode using dotnet build -t:Run -f net8.0-android -p:AndroidSdkDirectory=/Users/yangfan/android-sdk -p:EmbedAssembliesIntoApk=true

Did I miss anything?

@fanyang-mono
I run my tests on an x64 android emulator. Maybe this is the difference?

[fanyang-mono]

@tranb3r From AndroidStripILAfterAOT feature's perspective, it shouldn't make a difference. Could you share the apk file where the failure happened?

[tranb3r]

@fanyang-mono I think you're building for Debug instead of Release.

Here is a simple command to build and run the apk:

• x86_64: dotnet build -t:Run -f net8.0-android -c Release -r android-x64
• arm64-v8a: dotnet build -t:Run -f net8.0-android -c Release -r android-arm64

Here are the corresponding apks:

• com.companyname.mauiappxunitinvalidilcode-Signed-x86_64.zip
• com.companyname.mauiappxunitinvalidilcode-Signed-arm64-v8a.zip

I've reproduced the error both on x86_64 simulator and arm64-v8a device.

@tranb3r I was able to reproduce with the apk file that you provided. Will look into it.

@fanyang-mono Hi, any progress? Thanks

[fanyang-mono]

@tranb3r I was caught up by some other projects. Will find some time to look into this this week. Sorry about the delay.

@fanyang-mono Sorry to ask again. Did you have the time to work on this issue? Thx.
