When working with Unreal and trying to build for Android (like the Oculus Quest) it recommends having 
version r14b of the Android NDK tools installed. You could install this manually by 
[downloading it](https://developer.android.com/ndk/downloads/older_releases.html) or you can install it via `homebrew`. 

Unfortunately the version available via `homebrew` is r19. The [legacy](https://raw.githubusercontent.com/Homebrew/homebrew-cask/249c1cf49bff6ddd6dc7c19fb8b6b33f2de0ccd5/Casks/android-ndk.rb) formula has some problems. 
This formula uses the legacy formula and adds the more recent installation fixes.

```bash
brew cask install https://gist.githubusercontent.com/jeffrafter/93e4efc2119e5ecd84b4367c9f9c655a/raw/058499c99a697649d5116fce1c9dfa204bb25e54/android-ndk.rb
```
