Export from Unity for Android Games?

So, I’ve recently finished my game, and it’s device is for android. So, should I export it as a Google Android Project? And, I’ve heard that if you export it with Google Android Project, that means that you’re using it in Android Studio/Eclipse that kind of thing. What are Android Studio/Eclipse for?? Aren’t you finish with your game? Can someone plz explain this.

When you publish from Unity for Android you’ll get an APK. There is nothing else you need to do.
