The stale LLVM IR manifest (which uses compat JNI names like "android.apptests.App") remained while the JCW was generated with the CRC-based name ("crc64.../App"), causing a name mismatch at runtime. Fixes: 1. Add a sentinel file (.trimmable) written when _GenerateTrimmableTypeMap runs. A new target _CleanStaleNonTrimmableState deletes the stale typemap DLL when the sentinel is missing, forcing regeneration. 2. Pass extraBuildArgs to the Clean step in apk-instrumentation.yaml so the Clean imports the same targets as the build and properly cleans trimmable-specific files.

Split TrimmableTypeMap.Initialize() into CreateInstance() + RegisterNativeMethods(). CreateInstance() runs BEFORE JniRuntime creation (so ManagedPeer..cctor() can resolve types via TrimmableTypeMap.Instance). RegisterNativeMethods() runs AFTER (because it needs JNI). This fixes a chicken-and-egg crash where ManagedPeer's static constructor triggered type resolution before the typemap was initialized. 2. Catch TypeLoadException in OnRegisterNatives for open generic definitions (e.g., TestInstrumentation`1). These types have JCW classes but can't be loaded via Type.GetType() as open generics. Registration is skipped — their native methods will be registered when the concrete derived class loads.

Use Java.Lang.Object as the JavaPeerProxy type parameter instead of the open generic type. Loading the proxy type forces the CLR to resolve its base class generic argument, and open generics from external assemblies can't be resolved by the TypeMapLazyDictionary loader. The T parameter only affects CreateInstance, which already throws for generic definitions. 2. Skip TypeMapAssociation emission for generic definitions. The association attribute references typeof(TestInstrumentation<>) which triggers the same cross-assembly open generic resolution failure when the runtime scans assembly-level attributes.

Export Runtime.registerNatives as a JNI native method from C++ so it's available via JNI auto-discovery when libmonodroid.so is loaded. Without this, calling registerNatives before the managed runtime initializes causes UnsatisfiedLinkError. The C++ stub is a no-op fallback — once the managed runtime starts, TrimmableTypeMap.Initialize() re-registers the method with the managed OnRegisterNatives callback. 2. Propagate CannotRegisterInStaticConstructor to all descendants of Application and Instrumentation types. Android loads Instrumentation subclasses before the native library, so ALL types in the hierarchy must use the lazy __md_registerNatives pattern instead of static {}.

Fix _RemoveRegisterAttribute override to reset _ShrunkAssemblies to _ResolvedAssemblies. When PublishTrimmed=true, ProcessAssemblies points shrunk items to R2R/shrunk/ which is only created by the (now no-op) _RemoveRegisterAttribute. Without this fix, CompressAssemblies and CreateAssemblyStore fail with DirectoryNotFoundException. 2. Exclude DoNotGenerateAcw types from ApplicationRegistration to prevent referencing deprecated android.test framework types. 3. Export Runtime.registerNatives from C++ as a JNI native method and propagate CannotRegisterInStaticConstructor to all Instrumentation/ Application descendants.

Add registerNativesFn to JnienvInitializeArgs struct 2. Set it to OnRegisterNatives during Initialize 3. C++ stub calls through the function pointer when set This ensures the correct class identity is maintained because the C++ stub receives the exact jclass from the JVM, and passes it directly to the managed callback. The managed RegisterNatives JNI call is removed since the C++ function pointer handles the routing.

Verified via unconditional logging during a full device test run that Java_mono_android_Runtime_registerNatives is never called when the managed TrimmableTypeMap.OnRegisterNatives handler is wired via JniEnvironment.Types.RegisterNatives. - src/Mono.Android/Android.Runtime/JNIEnvInit.cs: drop the now-unused registerNativesFn assignment. - src/Mono.Android/Microsoft.Android.Runtime/TrimmableTypeMap.cs: restore the 'u8' optimized JNI type name literal 'mono/android/Runtime'u8. All 794 CoreCLRTrimmable device tests still pass.
