On Android you already have java :)

The big question is iOS for which there is no mature tool yet. hopefully j2objc will be enough.

Windows phone ...i think that we will wait to see a higher market share before to dig into it

> On Android you already have java :)

Java 6! Java 7 is only fully available for 4.4 upwards, and only the language, with cherry updates for the library.

Meanwhile one needs to resort to Xtend and Scala, if I want to enjoy a bit of Java 8 on Android, across versions. Or use hacks like retrolambda.

On Windows Phone vs iOS, it depends on your target market. On countries like mine (Portugal) you will surely see more WP on the street.

Of course, US and others are a different matter.

I am using java 1.5 features only :) Actually i never understood this spike about language features. For me the focus is always on the problem what i am trying to solve (VoIP in this case) and never the language. Actually any language would do for me in which i can apply some encapsulation for better code management (think of java classes). The rest doesn't matter :) I was started with C and then C++, but for me C++ is still C with classes :)

You should really read about the Blub Paradox. Imagine writing all your coded in assembly. It would suck because assembly is an inferior language To those you mention. Now imagine working in a language that is higher level than what you've (yet) been exposed To.

We are working hard on making RoboVM as mature as possible. There's already plenty of applications on the App Store using RoboVM. Happy to talk if you need more info for decision making. Ping us at [email protected].
