Description
What is this course about?
This course will help you understand how to work with the Internet on an android device, how to download and display a picture, which libraries and tools to use for this.
My course will have a number of distinguishing features:
I will use the startup method. That is, try to do things so that we can see the results faster, whatever they may be, and write less code at the same time. Because, from my point of view, visual validation helps us know that we're moving in the right direction. So the initial versions of the application will not be quite architecturally correct. However, we will fix this later on.
I will try to use all new technologies: Glide, Picasso, Jetpack compose, HttpURLConnection, OkHttp, Json, Gson, RxJava, coroutines, Flow, Retrofit, MVP and others. Exactly the ones that are required in the android developer jobs.
I will try to do one action in several ways, so that you have a choice and an understanding of what's going on.
I will provide complete code so that you can insert it into your project and reproduce it without too much difficulty.
We will go from the simple to the complex, but always rely on the visual result.
After completing the course, you will be able to make an application that will display a list of photos from the Internet.
Who will benefit from this course?
This course will be useful for intermediate-level android developers who have no experience with the Internet yet. Beginner developers who have no experience at all will probably not be able to take it. You're better off taking the beginner's course and then coming back to this course.

Leonid Ivankin
senior android developer
I wanted to be a programmer when I first saw a computer 25 years ago. Then it was old computers running MS-DOS and the recently released Windows 95. Unfortunately, fate decreed that after university I did not work as a programmer, as I wanted. However, I always dreamed of becoming a programmer, and as a result, I became one.
I became involved in android development, because I was struck and still is struck by the number of people who use devices with this operating system. I also like the fact that you see the result of your work every day and can show it to your family and friends. You can open the app and say, " Look! I did it!"
I try to constantly expand my horizons of android development and around it. Every day I read documents, articles, books. I was involved in the internal accelerator to understand how everything works on the outside. I follow the principle: either I don't take the job, but if I take it, I will finish it, no matter what it takes. I really appreciate the good relations in the team.
