Rust Binaries

Let us start with a simple application. At the root of an AOSP checkout, create the following files:


rust_binary {
    name: "hello_rust",
    crate_name: "hello_rust",
    srcs: ["src/"],


//! Rust demo.

/// Prints a greeting to standard output.
fn main() {
    println!("Hello from Rust!");

You can now build, push, and run the binary:

m hello_rust
adb push "$ANDROID_PRODUCT_OUT/system/bin/hello_rust" /data/local/tmp
adb shell /data/local/tmp/hello_rust
Hello from Rust!
