The lecture is interesting, thank you

Even though it's clearly 6 years ago, it seems much better than the lectures given recently. Other people do it all by themselves and then wonder why it doesn't work, but this person definitely tells you that you have to see this before it doesn't work so you can know if there's an error, so you can predict if there's an error or solve it while watching the video if it's difficult. There's also the textbook you mentioned on Google, and it's definitely fun to learn.

Thank you for the Firebase lecture.

Thank you for the long lectures from Java to Android. I'm completely brainwashed. Take care of your health.

Thank you for sharing the good lecture.

You can learn in a fun way by making games as examples!

Thank you~!!!
