Article. How to set up an Android project from scratch?

Question

Android

Hello!
Somehow I came across an interesting article on Habré, which talked about Android programming for beginners. Its peculiarity was that it described in detail what works and how, all the details of setting up a project from scratch, as well as how to make the project as easy and efficient as possible (without using unnecessary libraries).
Now I tried to find it - I did not find it. Unfortunately, I couldn't remember more details.
Help me find.
