Up-to-date resources on Kotlin and mobile development?

Question

Android

I'm starting to learn kotlin and android to run mobile applications (not games). Faced with the fact that everything is either about Java, or very old, or all together. I found the newest book in Russian on Kotlin in 2020, written in 2019, and infa there 2018. And there is only one such book, all the rest are still from mammoths. In addition, it is based on Kotlin on the web, and not in android. In total, there are 3 books on Kotlin in Russian and they are already quite old.

Is there something exactly according to Kotlin with a bunch of android, so as not to collect little everywhere and then try to blind it all somehow? Courses, websites, channels or something else, but only in Russian. I watched an interview with one proger on YouTube, he said that because. the company that created Kotlin is Piterskaya, then there is a lot of information in Russian, but on their website everything is in English and I did not find anything special on the net. Maybe there is something? I would be glad for any info

. I also saw similar questions in the header, but they were already many many years ago and the resources there are sometimes already in 2011, so I ask again

PS: Only free options

Answer 1

That is, you could not even find the documentation for Kotlin in Russian? So you don't want to invest a dime? What do you expect?
Infa has not changed much over the years, especially at your level. If you copy Java code, then it will automatically convert to Kotlin. I suspect that in the "old" books there will not be about coroutines, but this is definitely not your level, when you get there it will be possible to read articles on coroutines specifically. The startandroid channel on YouTube is still there.
In general, it is better to first learn how to use the search engine better. All the answers to your questions and mistakes are already on the Internet and most likely in English.
Start by learning programming, not the language
