Use method in .jar for Android Unity build

I have an SDK for native Android in a .jar file and want to use that for building on an Android device within Unity. There’s one method in that .jar that I would like to call on my opening scene.

What’s the best way to access the .jar’s method such that I can call it in C# on my Unity scene?

You need to put the jar into the proper folder (Plugins/Android) and then use the JNI script interface.
