What is the best way to start learning android development in 2018?

Question

Java

I have experience in programming in JS and Python (flask), but my soul is drawn to mobile development for Android, but which language is better to start with, there is a large variety of React native, Xamarin, Java-Kotlin, what would you advise?

Answer 1

You should definitely start developing android applications using Android Studio and Java for the following reasons:
1) Android Studio is the official development environment
2) Java is the native language for Android
3) A wide variety of books and lessons
4) A large community

Answer 2

React and Xamarin are environments for making cross-platform apps. IMHO, it's better to know Java and Swift than to depend on react or switch to sharps, which, of course, will never be natively supported by the bucket
