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

Answer 1

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 :)

Answer 2

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).

Answer 3

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

Answer 4

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.

Answer 5

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

Answer 6

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 & 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.
