create build.rs in project `fn main() { let target = std::env::var("TARGET").unwrap(); if target.contains("android") { println!("cargo:rustc-link-lib=c++_shared"); println!("cargo:rustc-link-arg=-fexceptions"); println!("cargo:rustc-link-arg=-frtti"); } }` and ,copy libc++_shared.so to your android project
