In what programming language is it better to write an application for Android?

Question

Android

Hello. Tell me please. I want to write applications for Android, but I can't figure out which language to choose for learning. I read on the Internet that Java is better, but now Kotlin has appeared and it is simpler, and Google is promoting it.

Answer 1

Kotlin is not easier. Java is easier. Kotlin has more concepts than Java, due to which the code on it is more compact. Therefore, IMHO, it should be more difficult to learn it. And it is under Android that you still need to understand what is happening in the jvm.
But in general, now you can learn Kotlin right away.

Answer 2

A modern Android developer needs to know both Java and Kotlin. Kotlin for developing new projects, Java for legacy and studying Android API sources.
Moreover, knowing Java, learning Kotlin is much easier, if only because many guides and tutorials refer to Java.
