The RunCheckedBuild flag was temporary validation infrastructure introduced to verify that linker-based JLO scanning produced the same results as the old process. The flag was never set to true (no definitions of _AndroidJLOCheckedBuild exist anywhere), making all code gated behind it dead code. Removes: - RunCheckedBuild property from GenerateJavaStubs, GenerateTypeMappings, GenerateACWMap, and TypeMapGenerator - CompareScannedAssemblies/CompareLists validation methods - Redundant JCW generation in GenerateJavaStubs - NativeCodeGenState-based overload in ACWMapGenerator - Duplicate GenerateACWMap invocation in targets file - scannedAssemblies parameter from XAJavaTypeScanner.GetJavaTypes Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Pull request overview
Removes the unused RunCheckedBuild / _AndroidJLOCheckedBuild validation infrastructure from Xamarin.Android.Build.Tasks, eliminating unreachable comparison/duplicate-generation code paths and simplifying task/target wiring.
Changes:
- Removed
RunCheckedBuild-gated code paths and associated plumbing across tasks/utilities. - Simplified typemap generation decisions to align with actual marshal-methods usage.
- Cleaned up MSBuild target invocations and task parameters related to the removed infrastructure.

| File | Description |
|---|---|
| src/Xamarin.Android.Build.Tasks/Utilities/XAJavaTypeScanner.cs | Simplifies GetJavaTypes API by removing the checked-build-only scannedAssemblies tracking. |
| src/Xamarin.Android.Build.Tasks/Utilities/TypeMapGenerator.cs | Removes checked-build output comparison/duplicate output behavior; always writes the generated typemap output. |
| src/Xamarin.Android.Build.Tasks/Utilities/MarshalMethodsCollection.cs | Updates call site for the new XAJavaTypeScanner.GetJavaTypes signature. |
| src/Xamarin.Android.Build.Tasks/Utilities/ACWMapGenerator.cs | Removes the checked-build-only Generate(NativeCodeGenState, ...) overload, keeping the JLO-driven path. |
| src/Xamarin.Android.Build.Tasks/Tasks/GenerateTypeMappings.cs | Drops RunCheckedBuild property and simplifies conditions/logging around native-state typemap generation. |
| src/Xamarin.Android.Build.Tasks/Tasks/GenerateJavaStubs.cs | Removes checked-build-only JCW generation/comparison plumbing and updates scanner call site. |
| src/Xamarin.Android.Build.Tasks/Tasks/GenerateACWMap.cs | Removes checked-build path and unused task properties; always generates from .jlo.xml ACW map entries. |
| src/Xamarin.Android.Build.Tasks/Microsoft.Android.Sdk/targets/Microsoft.Android.Sdk.TypeMap.LlvmIr.targets | Removes checked-build parameters/duplicate task invocation; aligns MSBuild task parameters with updated task APIs. |

Summary
The
RunCheckedBuildflag (set via_AndroidJLOCheckedBuildMSBuild property) was temporary validation infrastructure introduced to verify that linker-based JLO scanning produced the same results as the old process. The property is never defined or set totrueanywhere in the codebase — no.props, no.targets, no tests — making all code gated behind it unreachable dead code.This PR removes the entire
RunCheckedBuildinfrastructure across 8 files (290 lines deleted).Changes
