Well, you can already build apps for Mac just using the standard JVM and iOS using http://www.robovm.com/, so I'm not sure what Codename One brings to the table that you couldn't already do?

Codename One has one Java API to access all device capabilities such as:camera, gps, file system, maps and more... and it has one Java API for lightweight GUI, which allows great portability between supported platforms. robovm is good but mostly relevant for games with libgdx.

Oh so it's like Xamarin but for Java?

Codename One and RoboVM solve different use cases. If you can live with the limitations of a "common denominator" API, a UI toolkit that tries to mimic the native look and feel ala Swing and a limited subset of Java 5, Codename One is great since it allows you to use a single codebase and deploy to many different device types.

RoboVM on the other hand lets you use all the native iOS APIs from within Java and has a runtime library based on Android which limits you only to roughly the Java 6 APIs. As long as you structure your code properly RoboVM makes it possible to reuse large portions of your code between the Android and iOS versions of your app. So if you'd rather build an app that is truly native with a native UI and still want to be able to share code with Android RoboVM may be a better fit. And it's definitely not just for games even though libgdx+RoboVM is a killer combination.

Codename One predated RoboVM by more than a year. Its a WORA solution whereis RoboVM Java for iPhone more like a tool to replace Objective-C.

It's a bit confusing - from looking at the tutorial videos in the docs, it seems you have to purchase the server in order to actually make the real build for a device, but the site doesn't really clearly state this.

I'd stick with robovm for cross platform capabilities, or, use Haxe.

That's not true, you can build apps for free. Codename One has a build server on the cloud, which simplifies the whole build env for the developer.(you can use a Win machine to develop for iPhone). The uses of this build machine has free account and paid accounts.

Can I build applications for free from start to finish directly on my computer without any internet connection? yes or no?

Please consider adding a support of building locally, without your servers. E.g. when you're already on mac, with iOS SDK and Android SDK set up, you shouldn't need to use some online services.

I wander how does it compare with Qt.

invalidname4• 12 years ago

Actually not that far from it. Although its in Java so its higher level abstraction and its more WORA oriented in the Java style. More like Swing.

So what is the difference between Codename One and libGDX? Gaming focus?

fishyfishy5• 12 years ago

well, yes this is one of the major differences
