UNITY JNI android plugin GetApplicationContext()

Question

I'm developing a plugin for Unity Android using JNI. I create the .jar file with my Java code, and then .so file with the c++ bridge. Everything works fine when I call my library from Unity side. So, my problem is that in several parts of my Java code, I need to access to the context of the main activity (UnityPlayer3d). I need a pointer to this activity to call the function GetApplicationContext().

How can I obtain this pointer? I think about passing the pointer from Unity to my Java class as a parameter, but first I have to get it in Unity side.

Here's some code to get the activity JNI style:

var unityPlayerClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
var unityActivity = unityPlayerClass.GetStatic<AndroidJavaObject>("currentActivity");
