Just a comment of appreciation. This video its 5 hours long, has subtitles (no automatic, writted subtitles), its well recorded, the concepts are well explained and the audio its really good. This channel really takes his time to make this content with a good intention and tries to create something with the best quality possible. Im really gratefull for their job and I really appreciate that they take their time to make this thing really good. For them, probably it would be easier/cheaper to not make the subtitles and upload more videos faster, but they put the effort and the time. They reslly care. Im deaf, I need the subtitles and for me its a gift to have the possibility for enjoy this content and learn it. I know that in the past they didnt make subtitles but they improved with time. Thank you amigos code for your content. I wish you the best! Have a good day! Lots love!

It's really good, just one thing to make it even better is remove the "join the waitlist" from beginning of every chapter, it's a bit distracting, I know you worked hard for it and it should be here, but before every chapter is a bit overkill, include it after, say, every 4-5 chapter and we are good to go, promotes your product and also give viewers 15-20 sec of relax timing. win-win for both.

Recommended but java is on its way striking for its position. Look at its amazing look of java21 boom. Okay it may not be the number one (recommended) language for Android development but its code is getting precise and more expressive each update. For the love of Java, lets wait for the premiere.
