(A review after listening to all the lectures) (I wrote it in a modified format (sound font) to make it easier to read, so please understand.) - The 'Basics' section organized before entering the section was 'very'well' organized - The instructor's know-how is included - This is a great place for test lectures. I didn't understand the tests in Google Code Lab, but I learned a lot from this lecture. (I was impressed by the basics section that previews the test section in the appendix. If you're worried about paying, take a look here.) - The lectures are simple and easy to understand. It'll be easy to complete, and I'm happy that I'll have a completed app as a reference after listening to the lecture. (Since there are many parts that have already been used in code labs, it was easy for me because it felt like a review, but I don't know about others.) (However, the fact that it is simple and easy can be both an advantage and a disadvantage -> It would be good for learners to supplement and look for parts that they don't understand or are lacking.) - Google teachers must have created Jetpack to make apps easy... The content is quite extensive and it's not easy to study. You won't be able to get everything you want just by watching this lecture, and it seems like learners will have to search and study more. - The lecture fee is definitely worth it, and if the company provides learning support, just pay without hesitation! You should do it yourself with your own money, but it would be good to buy it during the Inflearn discount and study with a sunk cost(?) (In conclusion, I recommend the lecture. You will get more from listening than not listening, and if you pay and watch it instead of worrying about the lecture fee or lecture quality, you will probably study up to Section 3.) - The instructor is kind and quick to answer questions. - If there's an Android lecture that I need next time, I'm willing to buy it. - There was a 3-star review on the course review, and I agree with some of it. (The screen transition is applied to the architecture, and since the file is split a lot, it can't be helped, but you have to follow the code and look at it, but the code is covered by the editor, or you end up pressing the undo button a lot when the scroll transitions. It would be good to have a 5-second gap so that you can press the next video on YouTube? It would be good to have a 3-5-second gap so that you can stop the video after the code is completed. Also, the instructor seemed to speak a little fast, but I don't know if it's because I lack listening skills or because it's my first time taking an English class and library, but there were parts that I had to listen to repeatedly to understand. The speaking speed is a matter of the student's likes and dislikes, and... it would be difficult to control, so I think you can just listen to it repeatedly.) I listened to a good lecture. Thank you.
