Add the Android target with rustup and specify it in the cargo build command to compile Rust code for Android.
Add the Android target to your Rust toolchain and specify it during compilation to build for Android devices.
rustup target add aarch64-linux-android
rustup target add x86_64-linux-android
cargo build --target aarch64-linux-android --release
This installs the necessary compiler support and generates a binary optimized for Android ARM64 or x86_64 architectures.
Rust needs specific instructions to create apps that run on Android phones, just like a car needs a different engine for racing versus city driving. Adding the Android target gives your compiler the right tools to build these mobile apps. You then tell your build command to use these new tools instead of the default ones for your computer.
