Cargo.toml

[lib]
crate-type = ["lib", "cdylib"]

Wraps main function using attribute macro ndk::glue::main:

src/lib.rs

#[cfg_attr(target_os = "android", ndk_glue::main(backtrace))]
pub fn main() {
    println!("hello world");
}

src/main.rs

fn main() {
    $crate::main();
}

cargo install cargo-apk
cargo apk run

Stdout is redirected to the android log api when using ndk-glue. Any logger that logs to stdout should therefore work.

Android logger can be setup using feature "logger" and attribute macro like so:

src/lib.rs

#[cfg_attr(target_os = "android", ndk_glue::main(logger(debug, "my-tag")))]
pub fn main() {
    println!("hello world");
}
