AndroidEnvironment build task doesn't work properly when environment text file changes

Android application type

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

Affected platform version

VS 2022 17.10 P2

Description

AndroidEnvironment environment variables aren't updated when the environment text file changes.

AndroidEnvTest_Debug_AnyCPU_net8.0-android_Build_2024-04-01T12_13_05.9187908-04_00.binlog.txt

Steps to Reproduce

Clone https://github.com/BretJohnson/AndroidEnvTest
Build & run it, on Android. Note that environment variables are output to Debug, e.g. ENV1=YYYY is in the Debug output on VS.
Update myenv.txt, say changing the first line to be ENV1=NEWVALUE. Stop & restart, which triggers a build.

Result: Note that the Debug output still has ENV1-YYYY, not the new value.

Did you find any workaround?

No, not yet - and a workaround is what I'd most like here, so looking for hints on that.

Relevant log output

See attached binlog (renamed to have a .txt extension so I can attach it, but it's a .binlog).

The corresponding target does appear to be set up to build incrementally correctly. _GeneratePackageManagerJava is fully rebuilt as shown below, but the updated environment contents do not make it into the app. Perhaps the issue lies somewhere in ApplicationConfigNativeAssemblyGenerator?

   1:7>Target "_GeneratePackageManagerJava" in file "/usr/local/share/dotnet/packs/Microsoft.Android.Sdk.Darwin/34.0.85/tools/Xamarin.Android.Common.targets" from project "/Users/peter/source/AndroidEnvTest/AndroidEnvTest.csproj" (target "_CompileJava" depends on it):
       Building target "_GeneratePackageManagerJava" completely.
       Input file "myenv.txt" is newer than output file "obj/Debug/net8.0-android/stamp/_GeneratePackageManagerJava.stamp".

Unfortunately after a quick look I can't think of an easy workaround without having to drop in a .dll with a patched _GeneratePackageManagerJava task, unless you want to delete your bin/obj folders in between builds temporarily...

@BretJohnson

Looking at the logs even _CompileNativeAssemblySources is running.
This is part of the native side. I guess the app is not being deployed which is why the new values are not showing up.

@BretJohnson are you able to repo using the -t:Install target from the command line?

If I make C# code changes and restart those are applied, so the app must be getting redeployed.

@BretJohnson

@BretJohnson I ment if you just change the myenv.txt file and then call -t:Install does that re-deploy the binaries?

I did that test: I updated myenv.txt and then did dotnet build -f net8.0-android -t:install -bl.
Here are the results:
msbuild.binlog.txt
