Java – is there a common language?

We are designing an application that can run on windows, OS X, IOS and Android It would be nice to use at least one language for most of the code, instead of having to use objective C for apple, c# or C for windows, and Java for Android

We are considering flex (and all its problems) as a way to avoid using different languages for each version, but Adobe has abandoned it, which is impossible in the long run Java once promised to be universal, but it seems that Apple no longer supports it as part of the distributed operating system. As far as I know, Microsoft has never supported it We don't want our users to have to download and install something so that they can use our application

Is there a solution? Or do we insist on building applications in multiple languages?

Solution

"Global" language is most likely to use virtual machine, so you can't escape "users must download and install something to use this application"... I think Java is your best choice. I don't want to deal with the language problem of compiling cost machine code
