I want to create an app using Android Studio, should I learn all three languages (cpp, Java and Kotlin) or just one??

Question

Should I learn all three or just one or two?

Answer 1

Android studio is easy for app making you dont need much code to learn but you want to have a basic idea of code you can, also watch some tutorial in youtube it can help you

Answer 2

just one, among Kotlin or Java (former is the new 'official' android language, later is the old one, but still valid as both are compiled in almost same bytecodes)

C++ is only used as complementary language, for advanced uses, not to develop apps with only it ^^
