. This allows you to access features like OS calls and third-party code libraries that would otherwise not be available to Unity.

The pages in this section describe the process of creating your own plug-ins for use in Android projects. The information on these pages assumes you already know how to create native plug-ins for Unity. For more information about native plug-ins and their uses, see documentation on native plug-insA platform-specific native code library that is created outside of Unity for use in Unity.
