I'm learning Android for the first time and I'm learning very well. The only thing I regret is that the recording doesn't work properly, so it's giving me a headache. :(
I am satisfied with the overall content.
I think it will be helpful to you to tell me the problem when you make future lecture videos. There is a phenomenon where the sound suddenly gets smaller or something. There is a habitual sound that the instructor makes after he finishes talking. I try not to pay attention to it as much as possible ^^;
Thank you for your hard work.
