What are the programming languages supported by mobile devices? Is there some list or can anyone make a list of some?
I don't what to search, but I as able to find 3:
Are these the most used? What other languages are there that are used quite often?
It's hard answering this question, because "used most" implies the need for some kind of statistics to back it up. Instead I present you with some examples.
Objective-C is more or less the default language for iPhone and iPad applications. Flash is verboten, but I think Adobe AIR is allowed, and MonoTouch (.NET)
Java is commonly used for Android applications, although you can probably use any language with a JVM application, so technically it could be Scala, Rhino, Jython.
You can use Lua, Python and more on Android with a program made for running scripts, released by Google outside of Market I think.
Nokia Maego and Symbian favours C++ if I recall correctly but I wouldn't be surprised if you could use virtually anything provided it is runnable on the platform.
Anyhow it varies a lot, and depending on the OS vendor, you can often use a multitude of languages as long as they allow it.
