SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables developers to compile Rust code into Android native libraries (.so) and integrate them into Android projects via Gradle JNI, streamlining cross-platform native development and performance-sensitive modules.

Core Features & Use Cases

  • Cross-compile Rust crates for Android targets (aarch64-linux-android, armv7-linux-androideabi, x86_64-linux-android, i686-linux-android) and produce stable .so artifacts.
  • Build and link native Rust libraries using cargo alongside the Android NDK toolchain, with a standard entrypoint (:core:engine:buildRustNativeLibs) registered by the ripdpi Android convention plugin.
  • Integrate the resulting libraries into an Android app via the Gradle jniLibs mechanism for seamless runtime loading and packaging.

Quick Start

Run the Gradle task :core:engine:buildRustNativeLibs to compile the Rust libraries and generate the Android-compatible .so files.

Frequently Asked Questions about rust-android-ndk

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I cross-compile Rust code to Android .so libraries using Gradle?▼

Cross-compile Rust code to Android .so libraries by running the Gradle task :core:engine:buildRustNativeLibs, which uses cargo and the Android NDK toolchain to build native libraries for Android targets.

What Android ABIs are supported when cross-compiling Rust native libraries?▼

Rust cross-compilation supports common Android ABIs including aarch64-linux-android, armv7-linux-androideabi, x86_64-linux-android, and i686-linux-android, producing stable .so artifacts for each target.

Do I need the Android NDK and cargo to build Rust libraries for Android?▼

Yes, building Rust libraries for Android requires both cargo and the Android NDK toolchain to cross-compile the code, alongside the ripdpi Gradle convention task :core:engine:buildRustNativeLibs to trigger the build.

How does Gradle JNI integrate Rust .so files into an Android app?▼

Gradle JNI integrates Rust .so files via the jniLibs mechanism, packaging the compiled native libraries into the Android app for seamless runtime loading and execution.

When should I use Rust for Android native development instead of C++?▼

Use Rust for Android native development when building performance-sensitive modules that require memory safety, compiling the Rust code into .so libraries and integrating them via Gradle JNI for cross-platform native development.

Why won't my Rust Android build task :core:engine:buildRustNativeLibs work?▼

The build task fails if cargo, the Android NDK toolchain, or the ripdpi Android convention plugin are not properly installed and configured, as these are required to cross-compile Rust and generate the .so files.
