cargo-ndk - Build Rust code for Android
This cargo extension handles all the environment configuration needed for successfully building libraries
for Android from a Rust codebase, with support for generating the correct jniLibs directory structure.
Installing
cargo install cargo-ndk
You'll also need to install all the toolchains you intend to use. Simplest way is with the following:
rustup target add \
aarch64-linux-android \
armv7-linux-androideabi \
x86_64-linux-android \
i686-linux-android
Modify as necessary for your use case.
Usage
If you have installed the NDK with Android Studio to its default location, cargo ndk will automatically detect
the most recent NDK version and use it. This can be overriden by specifying the path to the NDK root directory in
the ANDROID_NDK_HOME environment variable.
Example: building a library for 32-bit and 64-bit ARM systems
cargo ndk -t armeabi-v7a -t arm64-v8a -o ./jniLibs build --release
This specifies the Android targets to be built (ordinary triples are also supported), the output directory to use for placing the .so files in the layout
expected by Android, and then the ordinary flags to be passed to cargo.
Supported hosts
- Linux
- macOS (x86_64 and arm64)
- Windows
Local development
git clone and then install the crate with cargo:
cargo install --path .Similar projects
- cargo-cocoapods - for building .a files for all Apple platforms, and bundling for CocoaPods
