Bumps [external/Java.Interop](https://github.com/dotnet/java-interop) from `b881d21` to [`6820a9cb`](dotnet/java-interop@6820a9c). ## Java.Interop changes pulled in - [`6820a9c`](dotnet/java-interop@6820a9c) [Java.Interop] Make JavaProxyObject.RegisterNativeMembers private again ([#1468](dotnet/java-interop#1468)) - [`a2159d7`](dotnet/java-interop@a2159d70) Remove NuGet dependency grouping from Dependabot config ([#1459](dotnet/java-interop#1459)) - [`a0ca676`](dotnet/java-interop@a0ca6760) [ci] Update agentic workflows to claude-opus-4.8 ([#1461](dotnet/java-interop#1461)) - [`6d8aef7`](dotnet/java-interop@6d8aef7b) Bump to dotnet/android-tools@1fb68b6 ([#1457](dotnet/java-interop#1457)) - [`cfca8ad`](dotnet/java-interop@cfca8ad) Upgrade gh-aw to v0.79.6 and recompile workflows ([#1460](dotnet/java-interop#1460)) - [`0104236`](dotnet/java-interop@0104236e) [JniValueManager] Make TryConstructPeer virtual ([#1456](dotnet/java-interop#1456)) - [`d7dbad5`](dotnet/java-interop@d7dbad5) Remove Java.Interop.Dynamic ([#1449](dotnet/java-interop#1449)) - [`0244c10`](dotnet/java-interop@0244c10) Split reflection-based JniTypeManager and JniValueManager behavior ([#1441](dotnet/java-interop#1441)) - [`9ca7064`](dotnet/java-interop@9ca7064) [Java.Interop] Remove legacy `NET` preprocessor paths ([#1451](dotnet/java-interop#1451)) - [`cd2fc12`](dotnet/java-interop@cd2fc12) Remove Java.Interop.GenericMarshaler ([#1450](dotnet/java-interop#1450)) See full diff in [compare view](dotnet/java-interop@b881d21...6820a9c). ## Changes in this PR (beyond the submodule bump) The Java.Interop bump — particularly [#1441](dotnet/java-interop#1441) (split reflection-based `JniTypeManager` and `JniValueManager`) and [#1449](dotnet/java-interop#1449) (removal of `Java.Interop.Dynamic`) — required a number of follow-on changes in `dotnet/android`: ### Runtime / `Mono.Android` - **Adapt Android runtime to Java.Interop reflection managers** — switch the `JavaInteropTypeManager` / `JavaInteropValueManager` hierarchy to the new reflection-based base types and update type/value manager construction to match. - **Change base type of value managers and type managers** so the runtime composes correctly with the new Java.Interop split. - **Suppress reflection manager trim warnings only** — narrow the existing trim suppressions so they apply to the reflection-only managers and don't hide other warnings. - **Suppress IL2068 on `ManagedTypeManager.GetTypeForSimpleReference`** — annotate the entry point that legitimately requires reflection so trim analysis is satisfied. ### Tests / apkdescs - **Regenerate `BuildReleaseArm64SimpleDotNet.MonoVM.apkdesc`** to track size changes from the Java.Interop bump. - **Regenerate Simple `BuildReleaseArm64` apkdescs** (`MonoVM` + `NativeAOT`) from a `Release` SDK so they match what CI produces. - **Update NativeAOT warning expectations** — `Mono.Android` now produces fewer trim/AOT warnings, so loosen the strict `4 Warning(s)` checks in `SupportedOSPlatformVersion` and `CheckSignApk` to `AssertHasAtMostWarnings (2)` (new helper in `AssertionExtensions`) and drop the `BuildHasTrimmerWarnings` data counts (`3 → 2`, `4 → 3`) accordingly. ### Merges - Two merges from `origin/main` to keep the branch current and resolve a conflict in `Microsoft.Android.Sdk.TypeMap.Trimmable.targets`.
