`checkRequiredEntryPoints` no longer accepts `android_main` as an
Android entry — `#jni_main #jni_class("...")` is now the sole accepted
path. The diagnostic walks the user through declaring an Activity +
Bundle foreign decl. `isExportedEntryName` drops `android_main` and
`ANativeActivity_onCreate` (both were for the legacy NativeActivity
glue path R.2 stopped linking by default).
Migrates the two cross-compile examples that previously carried an
`android_main` trampoline to a minimal `#jni_main #jni_class(...) { }`
stub:
- `examples/ffi-jni-call-02-void.sx` — tests `#jni_call(void)` lowering
- `examples/ffi-objc-call-10-os-gate.sx` — tests `inline if OS` gating
Both stubs are empty (no `onCreate` body) so they exercise the
entry-point check + R.3's JNI-symbol synthesis pass produces no
symbols. 131 host / 4 cross / zig build test all green.
`examples/99-android-egl-clear.sx` still uses `android_main` and the
AndroidPlatform/native_app_glue stack — its Android-target build now
fails the entry-point check. R.5 removes it along with the rest of
the legacy NativeActivity surface.

// Phase 1 step 1.15 (PLAN-FFI.md): `#jni_call(void)` codegen.

|
|
// `#jni_call(T)(env, target, "method_name", "(Sig)RetSig", args...)`
|
|
// dispatches a JNI instance-method call. The lowering hand-emits the
|
|
// vtable indirection:
|
|
//
|
|
// ifs = *env // JNINativeInterface*
|
|
// cls = ifs->GetObjectClass(env, target)
|
|
// mid = ifs->GetMethodID(env, cls, name, sig)
|
|
// ifs->Call<Type>Method(env, target, mid, args...)
|
|
//
|
|
// Phase 1.17 introduces method-ID caching via static slots populated
|
|
// at module-init; this step keeps the per-call-site lookup.
|
|
//
|
|
// Host can't dlopen libjvm via the JIT, so the JNI body is gated
|
|
// behind `inline if OS == .android`. The macOS test path strips the
|
|
// body and prints "skipped"; the cross_compile.sh Android target
|
|
// verifies that the gated body actually compiles + links against
|
|
// libjvm in the Android sysroot.
