I had been continuously trying to study Android for several years, but I couldn't reach the level where I could create apps. I had a strong desire to make apps, but I couldn't actually create them, which was very disappointing. Then I discovered instructor 개복치's lecture on Inflearn, and I had a feeling that if I took this course, I would be able to gain enough knowledge to create apps. I diligently watched the video lectures from Kotlin basics to dating app development, and during this process, I encountered bugs and went through continuous trial and error, but the instructor's bug-solving tips were helpful. Of course, when bugs occurred, the resolution process was difficult, but with diligent googling, it wasn't at an impossible level - it was challenging but solvable. (I think there were about 7 bugs, but I managed to solve them somehow) Bug solving seemed to be an experience that gradually improved my low-level skills. Thanks to instructor 개복치, I completed the dating app by following the lectures, and additionally developed SMS text verification functionality, which became a great learning experience. I recommend this course to those who are starting Android app development for the first time and those who have started but are experiencing difficulties~^^ Thank you for reading.
