Call native plug-in for Android code

The process to call code in native plug-ins for Android is the same as standard native plug-ins.

Note: If you use individual C/C++ source files as plug-ins, use __Internal as the plug-in name in the DllImport attribute.

It’s best practice to wrap all native plug-in method calls with an additional C# code layer that:

  • Checks Application.platform and only calls native methods when the application is running on Android devices using the architecture that you compiled the native plug-in for. On other platforms and architectures, the additional C# code layer should return dummy values.
  • Uses platform defines to control platform dependent code compilation and only compile code that uses the plug-in on platforms that have the plug-in available.

Sample package

The AndroidNativePlugin.unitypackage zip file contains a simple example of a native code plug-in distributed as a Unity package.

The sample shows how to invoke C++ code from a Unity application. The package includes a scene which displays the sum of two values as calculated by a native plug-in. To compile the plug-in, use Android NDK. For information on how to install Android NDK via the Unity Hub, see Android environment setup.
