How can one develop iPhone apps in Java? [closed]

Answer 1

I think Google Open Sources Java To Objective-C Translator will make it possiblöe to develop in Java for iOS https://code.google.com/p/j2objc/

Answer 2

I think your teacher sent you down the wrong path.

This is a classic example of trying to put a square peg into a round hole. The best way to develop for the iPhone is with the iPhone SDK and objective C. The best way to develop for Andriod is Java and the Android SDK. The best way to develop for WinMobile is C#/VB and the .Net Framework.

As you can see each has their own "best" SDK. Since you are only learning Java I would second the suggestion to play around with Java and Android.

Answer 3

take a look at codenameone.com project, it's a cross platform mobile framework where the ui part is a fork of LWUIT. This project leverage xmlvm to translates the java bytes code to Objective C

Answer 4

try to use TotalCross. It is a Java Framework to help devs create iOS and Android apps with only one source code. Different from the others platforms, it doesn't require any knowledge in iOS (Objective-C or Swift) nor Android (SDK or NDK)

there is a maven integration https://gitlab.com/totalcross/TotalCross/wikis/building-with-maven

Answer 5

To add to this there's: http://www.oracle.com/technetwork/developer-tools/adf-mobile/overview/index.html

A Java & HTML5 Based Framework for Developing
Oracle ADF Mobile enables developers to build and extend enterprise applications for iOS and Android from a single code base. Based on a hybrid mobile architecture, ADF Mobile supports access to native device services, enables offline applications and protects enterprise investments from future technology shifts.

Answer 6

Even if the question states Java, most of the answers have digressed. So I thought I would do the same :)

We have been using Adobe AIR for the last 5 years and it is truly cross-platform and provides native-like performance with the same code base (at least 99% of our code is the same). Adobe AIR got some bad press at the beginning during the 'beta' period (slow, no GPU, Flash 'dead' etc.) But now, it's amazing what you can do with it. Not to mention the wealth of open source libs out there.

With the same code base you can push your app onto:

• iOS
• Android (x86 and ARM)
• Flash (still VERY useful)
• ChromeBook
• PC (as native with installer)
• Mac (as native with installer)

Why bother with Java or Objective-C ?

The only common platform not covered is Window Phone. But that's coming soon too.
