Java or Kotlin for Android app development?

Question

Android

I ask this question in connection with the recent events where Google declared Kotlin the official language of Android (according to the translation of the article). However, before that, everyone used Java, but now it turns out that it is not relevant?

Answer 1

Official languages ​​are C++, Java, Kotlin. Support for these languages ​​is guaranteed in Android Studio. Kotlin is fully compatible with Java. Moreover, in one project, you can use both Kotlin and Java at the same time. Java will always be relevant.
