描述

Area: App Runtime bug trimmable-type-map

Android framework version

Other, net11.0-android (Preview)

Affected platform version

11.0 RC2

Description

When you have <AndroidTypeMapImplementation>trimmable</AndroidTypeMapImplementation> in your csproj and you use a method that retuns Java.Lang.Object and you use a regular type cast. Like in my repro sample I use this.GetSystemService(Context.StorageStatsService) and cast it to StorageStatsManager? then the StorageStatsManager type is trimmed away and the code ends up throwing a InvalidCastException.

var service = (StorageStatsManager?)this.GetSystemService(Context.StorageStatsService);

If I use .JavaCast<StorageStatsManager>() the type is retained and all is good.

var service = this.GetSystemService(Context.StorageStatsService).JavaCast<StorageStatsManager>();

Steps to Reproduce

I have a small repro here: https://github.com/Cheesebaron/JavaLangObjectCastIssueNet11
Run it with dotnet run --project net11cast/net11cast.csproj /p:Configuration=Release

Create new Android project targeting net11.0-android
Add <AndroidTypeMapImplementation>trimmable</AndroidTypeMapImplementation> in your release config
Use a method like GetSystemService() which returns Java.Lang.Object
Type cast the Java.Lang.Object to something concrete like StorageStatsManager
Run in release mode

Did you find any workaround?

No response
