Android

The Android generator produces a Gradle android-library template with:

• Kotlin wrapper WeaveFFI that declares external funs
• JNI C shims that call into the generated C ABI
• CMakeLists.txt for building the shared library

Generated artifacts

• generated/android/settings.gradle
• generated/android/build.gradle
• generated/android/src/main/java/com/weaveffi/WeaveFFI.kt
• generated/android/src/main/cpp/{weaveffi_jni.c,CMakeLists.txt}

Build steps

1. Ensure Android SDK and NDK are installed (Android Studio recommended).
2. Open generated/android in Android Studio.
3. Sync Gradle and build the :weaveffi AAR.
4. Integrate the AAR into your app module. Ensure your app loads the Rust-produced native library (e.g., libcalculator) at runtime on device/emulator.

The JNI shims convert strings/bytes and propagate errors by throwing RuntimeException.
