How to switch to Android development?

Question

Java

Good afternoon! Have there been questions.
How to switch to android development (native)?,
where is the best place to start?
What test project do you recommend? preferably Kotlin.
The fact is that I am not a beginner (good knowledge in js / c #) in the world of programming, but for some reason native development is a bit difficult. I would be grateful for advice and suggestions.

Thank you for attention!

PS I have already begun to quietly study the development
