-Bevy may require `libc++_shared.so` to run on Android, as it is needed by the `oboe` crate, but typically `cargo-ndk` does not copy this file automatically.

-To include it, you can manually obtain it from NDK source or use a `build.rs` script for automation, as described in the `cargo-ndk` [README](https://github.com/bbqsrc/cargo-ndk?tab=readme-ov-file#linking-against-and-copying-libc_sharedso-into-the-relevant-places-in-the-output-directory).

-Alternatively, you can modify project files to include it when building an APK. To understand the specific steps taken in this project, please refer to the comments within the project files for detailed instructions(`app/CMakeList.txt`, `app/build.gradle`, `app/src/main/cpp/dummy.cpp`).
