 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`).

 For the moment, everything is single threaded, this can lead to stuttering when playing audio in browsers. Not all browsers react the same way for all games, you will have to experiment for your game.
 
 In browsers, audio is not authorized to start without being triggered by an user interaction. This is to avoid multiple tabs all starting to auto play some sounds. You can find more context and explanation for this on [Google Chrome blog](https://developer.chrome.com/blog/web-audio-autoplay/). This page also describes a JS workaround to resume audio as soon as the user interact with your game.
