android-kotlin-fundamentals-apps VS guide-to-kotlin

Anyway, there is minimal Codelabs example with a tutorial. Also from my experience you might want to find and watch video with explanation - somehow it can be perceived easier than a wall of text. So maybe this or this can be helpful.

Read through https://github.com/Zhuinden/guide-to-kotlin/wiki and you'll know Kotlin. That, and you can also check the collection APIs which are pretty much the best thing in Kotlin compared to Java.

I would recommend learning Kotlin for Android though, it does help. I wrote this guide https://github.com/Zhuinden/guide-to-kotlin/wiki but you can also look at this video https://www.youtube.com/watch?v=wuiT4T_LJQo

I wrote this guide for Java => Kotlin a few years ago, other than me not adding coroutines it still holds: https://github.com/Zhuinden/guide-to-kotlin/wiki

Check this guide by me to learn Kotlin: https://github.com/Zhuinden/guide-to-kotlin/wiki

but you can read through https://github.com/Zhuinden/guide-to-kotlin/wiki and you will know what you need to know for Kotlin basics (except coroutines, then you watch https://www.youtube.com/watch?v=6P20npkvcb8 )

I wrote https://github.com/Zhuinden/guide-to-kotlin/wiki a few years ago for people who know Java and don't know Kotlin, I've heard many positive feedback for how simple it is to transition from Java to Kotlin once reading through it.

you should probably look into Kotlin (see https://github.com/Zhuinden/guide-to-kotlin/wiki and/or https://www.youtube.com/watch?v=wuiT4T_LJQo ),

You actually can just read through https://github.com/Zhuinden/guide-to-kotlin/wiki and you'll know how to use kotlin lo

I wrote this guide a while ago specifically to cover this kind of migration https://github.com/Zhuinden/guide-to-kotlin/wiki it should be fairly no-nonsense and I've heard people like it (they said it helped them).

I didn't need to because by the time it came out I already knew Kotlin, personally I wrote this https://github.com/Zhuinden/guide-to-kotlin/wiki
