Updating Android project after making changes in Unity?

Hello,

I’ve exported Unity project as Android project and imported it to Android Studio. In Android studio, I’ve added some methods which call C# methods.The problem is when I make changes to Unity project. If I export everything as a new Android project, I lose all the methods that were previously there. Is there a way to just update existing Android project after I’ve made some changes in Unity?

You can export project to new folder, copy assets folder and replace in Android Studio.
