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.

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 

Usage

You'll also need the NDK installed somewhere, and the path to it exported as the ANDROID_NDK_HOME environment variable. If you use Android Studio and have ANDROID_SDK_HOME defined, cargo ndk is smart enough to detect the ndk-bundle subdirectory as well.

Building is very similar to any other Rust project, with the addition of the --platform flag for selecting which Android API platform to target. By default, 21 is a good choice.

cargo ndk --platform 21 --target x86_64-linux-android build

Add --release for a release build, as per usual.

NOTE: Minimum supported NDK version is r19c. Has been tested up to r21.
