How to make an app for Android?

Question

What is needed for it? Which language I should leran to make it?

Answer 1

What field of Android development do you want to do?
But I know that you should know Java almost for anything.

Answer 2

Java is the most popular language for coding Android applications. One way to do so may be to use the Eclipse IDE (IDE being a program to write code-in) with an Android Development Tools plug-in (plug-in being a piece of software that adds additional functionality to an existing program), set-up an Android virtual machine and get to coding. I'd search up how to do all this, but Java is your go-to. Though you can use other languages.
