// `#jni_main` pipeline slice 2 (PLAN-FFI.md): the compiler renders a // `.java` source for a `#jni_main #jni_class("...")` declaration, runs // `javac` + `d8`, and bundles `classes.dex` into the APK. // // Slice 2 only wires the plumbing — the manifest still points at // `android.app.NativeActivity`, so the user's class isn't loaded at // runtime. Slice 3 (manifest synthesis) and slice 4 (RegisterNatives) // land in follow-up commits. // // Build to inspect APK contents (requires Android SDK + JDK): // /Users/agra/projects/sx/zig-out/bin/sx build --target android \ // --apk /tmp/sxjnimain.apk --bundle-id co.swipelab.sxjnimain \ // -o /tmp/libsxjnimain.so examples/ffi-jni-main-01-emit.sx // unzip -l /tmp/sxjnimain.apk | grep classes.dex #import "modules/std.sx"; #import "modules/compiler.sx"; // `*Bundle` resolves through the class registry to `android.os.Bundle` // in the emitted Java — needed for `onCreate`'s @Override to match // NativeActivity's superclass signature. Bundle :: #foreign #jni_class("android/os/Bundle") { } // `#jni_main` flags this as the launchable Android Activity class. The // `onCreate` body is empty for now — slice 4 wires `RegisterNatives` // so the `sx_onCreate` native delegate actually binds to a sx-side fn.
