What you need to know to move to the development of android applications?

Question

Java

Hello, what do you need to know for Android development? I know that they are developed in JVM languages ​​(Java, Scala, etc.). Interested in whether knowledge of only one of these languages ​​is enough, or will it be necessary to learn something additionally? It seems like Android Studio uses XML to design the interface (as an example).

Answer 1

Java+Android SDK + Understanding the Android Architecture + Application Life Cycle.
