-```
-
-## Issue
-
-The trimmable type map build tried to clean the Java source output directory, but the configured input and output directories resolved to the same path.
-
-Cleaning the output directory in this configuration would delete the input Java sources before they can be copied.
-
-## Solution
-
-This error indicates an internal build configuration problem. File an issue at <https://github.com/dotnet/android/issues> and include the full build log.

-
-## Issue
-
-The post-trim trimmable type map scan expected to copy a generated Java source file from the pre-trim Java source directory, but the file was missing.
-
-This can happen if intermediate build outputs are stale or if the generated Java source list no longer matches the files on disk.
-
-## Solution
-
-Delete the project's `obj` and `bin` directories, then rebuild.
-
-If the error persists after a clean rebuild, file an issue at <https://github.com/dotnet/android/issues> and include the full build log.

+# .NET for Android warning XA4256
+
+## Example message
+
+```
+warning XA4256: Skipping Java peer type 'Google.Android.Material.Shadow.ShadowDrawableWrapper' from assembly 'Xamarin.Google.Android.Material' because referenced type 'AndroidX.AppCompat.Graphics.Drawable.DrawableWrapper' from assembly 'Xamarin.AndroidX.AppCompat.AppCompatResources' could not be resolved in '/home/user/.nuget/packages/xamarin.androidx.appcompat.appcompatresources/1.6.0/lib/net6.0-android31.0/Xamarin.AndroidX.AppCompat.AppCompatResources.dll'. This type will not be included in the trimmable type map.
+```
+
+## Issue
+
+The trimmable type map found a Java peer type whose managed base type or implemented interface references a type that is not present in the resolved assembly set.
+
+This can happen when NuGet packages in the Android binding graph were built against different versions of another binding package. The type may be unused by the app, but NativeAOT compiles a closed world and must resolve rooted managed types eagerly.
+
+## Solution
+
+If your app uses the skipped type, update the affected NuGet packages so the referenced type exists, or update to versions of the binding packages that are compatible with each other.
+
+If your app does not use the skipped type, no action is required. The type is omitted from the trimmable type map so NativeAOT does not fail while resolving unused stale metadata.

+    @(_ShrunkAssemblies) destinations live inside the shared NuGet runtime pack
+    (e.g. .../runtimes/<rid>/lib/net11.0/shrunk/<assembly>.dll).
+
+    On NativeAOT the managed framework/user assemblies are compiled to a native shared

+    therefore unsafe: concurrent builds (multiple projects and the parallel per-RID inner
+    builds) target the same shared files, so they race and fail intermittently with
+    XACIC7028 (FileNotFoundException) on a clean pack cache.
+
+    For NativeAOT, redirect the shrunk copies to a project-local intermediate directory
+    instead of the shared runtime pack. They are still produced with CopyIfChanged so the
+    copies keep stable timestamps (only rewritten when content actually changes), which

+    @(_ShrunkFrameworkAssemblies) as inputs — while never writing into the shared pack.

+    The Copy task below then updates android/src only for Java sources whose content changed.
     We keep _GetGenerateJavaStubsInputs in DependsOnTargets so that downstream targets
     (_GetGeneratePackageManagerJavaInputs) can still read @(_GenerateJavaStubsInputs).
