No lecture audio, no concept explanation, lots of copy & paste (It's roughly written in the expected question Q&A) In fact, you can learn the concepts and implement projects for various latest Android technologies just by referring to the official documentation and Googling, but the learning process can be more boring and long than you think, so I think it's okay to buy it if you want to skip that and just complete the project and learn. Conclusion: This is a lecture that teaches you how to set up a feast on the table and eat the rice, but omits information about each food and how to eat it deliciously.

I bought it because I could study exactly what I wanted at a low price. However, since it was a lecture from two years ago, there were many codes that could not be applied, so I had a hard time. I had problems from the first DSL. There were parts that caused errors even when I changed the code posted in the notice. Fortunately, I had also taken other Hilt lectures, so I was able to write it so that it would run by comparing it with the code I used then. However, I couldn't finish the app because the API used in the lecture was deprecated. If you want to check the example codes for using the MVVM pattern, Hilt, and Firebase, you can buy it, but I don't recommend it to those who want to know in detail why they should be used and how the code works.

First of all, in the part where there is no sound... I think it will be hard for those who don't know much to understand. I bought it without knowing that there was no sound because I wanted to see how to use parts like hilt... There are subtitles, but they are a bit poor.. The source codes are also taught by pasting and pasting codes uploaded on GitHub (without any explanation), so honestly, it feels like I just paid for the codes.. I think it would have been better if they had put a little more money on the lecture and made it a lecture with sound. I think it was really good that I was able to experience Clean Architecture. I look forward to the future lectures with Ansop Woohwa's voice.

While taking the lecture, I didn't really know how to use Clean Architecture and MVVM design patterns, but thanks to the lecture, I learned a lot about those areas.

I don't think there is an Android lecture as good as this one. I didn't know how to use a realtime database, but I think I learned it through this lecture. I'm going to make a chat app based on what I learned in this lecture! If you are willing to learn Firebase application or dependency injection, I recommend it to those people! Even if you are not, I think it's worth watching at least once.

This year, after I started Android development, I studied the basics vaguely and had no direction on what to develop, when I came across this lecture. I didn't even know the concept of MVVM, but this lecture taught me how to apply MVVM and developed practical Firebase skills, so I was able to create an app. I will become a person who studies even more in the future.
