Can I run or develop iPhone apps in Java?
I'm actually a little confused ...

This is an open discussion.
Any ideas are welcome.

Thanks to everyone.

Answer 1

There is currently no JVM on the iPhone. This means that the only way to develop iPhone applications in Java is to have a compiler that compiles your Java code to Objective-C.

There are several solutions that do just that:

Codename One - focuses on building Java applications with visual tools and simulators. An open source SaaS backend that eliminates the need for a Mac.

XMLVM is a translator for converting Java bytecode to C / Objective-C. Open source, but at the moment you need to write specific iOS code.

There are also some proprietary solutions, but I have no experience with them. For example. AG software has a tool called web objects.

Answer 2

Sun has discovered that they can port Java to the iPhone, but the SDK license prohibits it. So this is not a technical, but a political issue.

Answer 3

I would say: No

If you want to create “real” native iPhone apps, you'll have to go with Objective-C and the iPhone SDK

There are other ways, for example http://phonegap.com/ , but I personally do not have experience with this project.

Answer 4

There is an implementation of the Java virtual machine called "Classpath", but the disadvantage is that you can only get it using Cydia / Installer.

So you need to jailbreak your iphone to install JVM.

gui can be designed as AWT-Gui.

in general: there is no solution (the apple does not allow applications that run other applications on their devices)

if you don't mind hacking the devices your application is deployed to: yes, there shouldn't be a big problem. there are a large number of tutorials on how to hack your iphone if you're interested ...

EDIT: there is a problem! If you do not have a libuicaboodle file, then every Java-based GUI application for iPhone is looking for, you will not be able to run the application. Is there anybode that still has this file? You can no longer find it: o (

Answer 5

Webapp can be developed in Java, of course, but you cannot run Java applications on Iphone (virtual machines are not authorized on the device).

There is some effort in Java to convert objective-c, as in XMLVM (check out the Google TechTalk video).

Answer 6

In the end, I can conclude that with the iPhone you can easily create web applications for the iPhone. To develop native iPhone applications in Java, you can use alcheMo or XMLVM with a small workload. I have no experience with alcheMo or XMLVM , but of course I'm looking forward to it.

Thanks to everyone.

Answer 7

There are several ways to write an iphone application for java using the xmlvm to c lens converter, but it is difficult, but it is a suitable and compatible way to make a ur application. You need to learn the XML language.

Answer 8

An interesting approach is to combine the Google Web Toolkit with the Appcelerator Titanium to develop iPhone applications using Java.

Google Web Toolkit (GWT) allows you to compile Java code in Javascript, while Titanium allows you to create visual iPhone applications in Javascript. I started a project called " gwt-titanium " to combine the two, you can find an explanation of the project and building instructions on the iPhoneJava.org blog.

Good luck

Answer 9

What about other Java compilers for native compilers, although there was one called Jet ?

Compiles java for native.
