src/android/. 15 Certifique-se de que adb sync funcione com seu emulador ou dispositivo físico e pré-compile todos os exemplos do Android usando src/android/build_all.sh. Leia o roteiro para ver os comandos diretamente, não através do cargo (a maioria dos usuários nunca o faz). – Pode valer a pena mencionar que o próprio Cargo é uma ferramenta extremamente poderosa e abrangente. Ele é capaz de muitos recursos avançados Playground real. 2.3 Executando Código Localmente com o Cargo Se você quiser experimentar o código em seu próprio sistema, precisará primeiro instalar o Rust. Faça isso seguindo as instruções no Livro do Rust
