What is the programming language for creating Android applications?

Java is the "official" language of the platform. No matter what you are going to do, essentially it is what you will use. So this is the objective answer to the question is that Java is the most used shot.

But it does not mean that only it can be used. I do not say majority, but a lot of people use other things. See more and more use C # or another .NET language using Xamarin . Google appears to be making this option official . Already officially Kotlin .

NDK is a way to use C and C ++ and some people use it.

It seems that Google has decided to invest in making Dart a strong language on Android.

If you prefer a hybrid application or even for the web, JavaScript becomes the option. And a lot of people have used it that way, even if it is not always the best option. It has several solutions in this sense. Cordova is just one of them. There are others .

There are even those who use Corona .
