How can one develop iPhone apps in Java

Question

I was wondering if is it possible to develop iPhone applications using Java plus XMLV  which claims to cross-compile Java-based Android applications to native iPhone applications  Is XMLV a viable way to develop iPhone applications using Java  Here are a few Java code examples used to build and application in an iPhone  http   www xmlvm org iphone

I think we will have to wait a couple of years more to see more progress. However, there are now more frameworks and tools available:

Here a list of 5 options:

Codename One
RoboVM <-- Closed
Avian no maintainer
XMLVM
J2ObjC
Multi-OS Engine not maintained

You can t   Note however that Monotouch allows you to develop in C  instead of Objective-C   http   monotouch net

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

You need to know at least basics of Objective-C to develop for iPhone  However  it is possible to use C   classes   As far as I know Adobe is working on building Flex Flash applications for iPhone  Read more here  http   theflashblog com  p 1513

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

Perhaps you should consider Android applications instead of iPhone applications if you really want to develop in Java for smartphones  Android natively uses Java for it s applications  so perhaps this might be a better option   As for iPhone  I would recommend you to look into Obj-C or C C   depending on the type of applications you want to make  Should be fun to dabble into a new language

I m answering this question 2 years down the line and I  must  stress that I did have pretty much the same problem as you did  However I m so happy that Android has evolved into what it is today       Having said that  I do regret that I did not learn C C   while I could have and I don t want to blame my teachers for it cos where was my brain when the time was right      I m sunk in Java today and I m glad that I did not make the mistake of learning too many languages and being less productive     However I did learn HTML5 which really made things a lot easier  maybe someday  I might get motivated to learn C C     Or if I get an Apple mac at a real throw-away price  I might learn Objective-C

You can try iSpectrum   get it at http   www flexycore com   You ll be able to develop and debug your Java apps in Eclipse  You ll still need a Mac and XCode to launch it on the simulator  or install it on the real device  though   But you won t have to actually use XCode editor  Plus you can use it for free if you re planning to work on an open source project

Build a hybrid app  Anyways Java is not enough for a software engineer   you need to learn JS HTML5 CSS as well for becoming a full stack mobile app developer  Build the complete backend using Java  amp  frontend using Cordova Phonegap   I m assuming you dont need the last drop of juice from the hardware even hybind app should suffice your needs   Build a responsive webapp using Bootstrap 4   React JS  Use https   github com ipselon structor to quickly build up the frontend  Now the web app becomes an app in the browser   You could also take the same app and build it using cordova to publish a app on ios android platform

If you ve completed your other projects  why not take the time to learn Objective-C   There is a ton of material out on the web to help you get started   Honestly  it won t be that hard and learning to do some memory management will be a great learning exercise   Have you programmed in C before   Most cross compilers won t do a great job in converting your code  and debugging your project may become much more difficult if you develop them this way

http   www xmlvm org android   Specifically talks about Java based Android apps being ported to the iPhone using non-Apple hardware   You might also want to check out MonoTouch  C  rather than Java   but the two are very similar

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

User · Answer

You can also take a look at RoboVM   It translates Java byte-code into native ARM or x86 code which can run directly on the processor without any VM or interpreter needed  Most of the Obj-C UI elements are already bridged into Java and follows the usual Java design patterns   Edit Robo VM recently announced that it would be shutting down the service - Source

If you plan on integrating app functionality with a website  I d highly recommend the GWT   PhoneGap model   http   blog daniel-kurka de 2012 02 mgwt-and-phonegap-talk-at-webmontag-in html http   turbomanage wordpress com 2010 09 24 gwt-phonegap-native-mobile-apps-quickly   Here s my two cents from my own experience  We use the same Java POJOs for our Hibernate database  our REST API  our website  and our iPhone app  The workflow is simple and beautiful   Database ---1---  REST API ---2---  iPhone App   Website   1  Hibernate 2  GSON Serialization and GWT JSON Deserialization   There is another benefit to this approach as well - any Java code that can be compiled with GWT and any JavaScript library become available for use in your iPhone app

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
