You can use plug-ins to deliver resources and call Java and C++ code created outside of Unity from your C# scripts. They enable you to access features, like third-party code libraries and operating systems calls, that would otherwise not be available to Unity. For more information about plug-ins with Unity, see Plug-ins.
This section describes how to create your own plug-ins and use them 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 Native plug-ins.
