⭐️⭐️⭐️⭐️⭐️ I'm leaving an additional star because five stars are not enough. This is the best lecture. The concept is explained in detail and easy to understand. I liked that difficult concepts such as the delegate pattern, MVC pattern, synchronous/asynchronous, MVVM pattern, and dependency injection were explained in an easy to understand way. I couldn't find a good explanation of similar concepts in Android, so thank you for helping me grasp the basic concepts.
