Does this make sense going to android-tools? and use that nupkg?

Yes, we should open a PR here to test out any new Adb APIs from dotnet/android-tools. None are merged yet, right?
It would be proof the new APIs work, though.
…trumentation support Context: #10683 Add a new `androidtest` .NET project template that creates an Android test project using MSTest with Microsoft.Testing.Platform. The template includes a TestInstrumentation class that runs tests via `am instrument` and reports results (passed/failed/skipped) back through Android's instrumentation protocol. Add `--instrument` option to Microsoft.Android.Run so `dotnet run` can launch test projects via `am instrument -w` instead of `am start`. Fix an issue where NuGet packages like MSTest add assemblies as both properly-resolved publish assets (with DestinationSubPath metadata) and as None items (without DestinationSubPath) that flow into `_SourceItemsToCopyToPublishDirectory`. When NuGet conflict resolution arbitrarily picks the None-based copy, the assembly loses its DestinationSubPath and TargetPath metadata, causing it to either be missing from the APK or deployed to the wrong directory on device. The fix conditionally removes only items without DestinationSubPath, then re-adds any assemblies that were completely stripped with a cleared TargetPath so that downstream targets (ProcessAssemblies, FastDeploy) can set the correct per-architecture paths. Changes: - New `androidtest` template under src/Microsoft.Android.Templates/ - New GetAndroidInstrumentationName MSBuild task to resolve the instrumentation runner class from AndroidManifest.xml - Updated Microsoft.Android.Sdk.Application.targets to pass `--instrument` when EnableMSTestRunner is true - Added AdbHelper class to Microsoft.Android.Run for shared adb process management - Added `--instrument` CLI option to Microsoft.Android.Run/Program.cs - Fixed _ComputeFilesToPublishForRuntimeIdentifiers to preserve properly-resolved publish assets and recover missing assemblies - Added DotNetNewAndroidTest device integration test TODO: - In a future PR, add support for `dotnet test` end-to-end.

Check pe.HasMetadata before calling GetMetadataReader() to avoid InvalidOperationException when processing native DLLs (e.g. from BenchmarkDotNet/TraceEvent NuGet packages) that don't have .NET metadata. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

MSTest test platform assemblies fail AOT compilation because the IL linker trims types (DoesNotReturnAttribute, MemberNotNullWhenAttribute) from Microsoft.TestPlatform.CoreUtilities that are still referenced via custom attributes in other test platform DLLs. Use MtouchInterpreter=all to bypass AOT and run all assemblies through the interpreter instead. See: dotnet/android#10862 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

…tifiers Compare by filename instead of full ItemSpec path when checking if assemblies from _SourceItemsToCopyToPublishDirectory already exist in ResolvedFileToPublish. Native DLLs like KernelTraceControl.dll (from Microsoft.Diagnostics.Tracing.TraceEvent NuGet) can exist under different paths, causing the old Remove-by-path to miss them and re-add duplicates that crash GetPerArchAssemblies with XALNS7004.

…meIdentifiers When _SourceItemsToCopyToPublishDirectory contains multiple items with the same filename from different source paths (e.g., KernelTraceControl.dll), _MissingAssemblyNames ends up with duplicate entries. These duplicates get re-added to ResolvedFileToPublish, causing a Dictionary duplicate key error in GetPerArchAssemblies (XALNS7004). Use RemoveDuplicates task to deduplicate by filename before re-adding, following the same pattern already used for NativeAOT deduplication.

NuGet packages like microsoft.diagnostics.tracing.traceevent (a
dependency of BenchmarkDotNet) include native Windows DLLs under
lib/native/{arch}/ paths. These were flowing through
_SourceItemsToCopyToPublishDirectory into _MissingAssemblyNames and
being re-added to ResolvedFileToPublish. When the linker tried to
load them with Mono.Cecil, it threw BadImageFormatException
(XALNS7000/XA0009).
Filter out items whose OriginalItemSpec contains a /native/ path
segment, which covers both lib/native/ and runtimes/*/native/ NuGet
layout conventions.
