Unity Getting started in Java phone programming

Recommended Posts

I have been looking over tons of websites trying to get everything together that I need for programming Java J2ME, specifically for my SPH-a660/VI660. I have been learning to program normal Java at a community college and have a little game experience in various other languages, and want to move into mobile game programming. I have still seem to be missing quite a bit though, such as the SDK. I'm not sure what I need for an SDK or where to find it (Sun doesn't seem to offer the actual SDK). Also, is it possible to use BlueJ to write the source (since that is what I learned on)? Not quite as related to programming, I can't seem to find the data transfer cable anywhere. Is there a certain site that I should look for it on? Thanks for the help!

The only SDK you need is the Sun WTK (Wireless Toolkit), which can be downloaded from Sun.

I'm not familiar with BlueJ, but any decent Java development environment should be fine to write code in. What's less clear is whether you'll be able to build and test your MIDlets from that IDE; if not, you'll have to use WTK for building and testing.

I seem to recall that many Samsungs don't do cable-based provisioning; you may need to do OTA (over-the-air) provisioning.

I just wanted to agree with Sneftel and add a few things...
Here is a link to the latest WTK from sun, which is basically all you need to start developing. You can write your code in anything you want, but personally I use the free version of JCreator.

You may have seen it already but this site has a nice little intro to J2ME that might clear up any questions you have. here

Good Luck!

And a cable won't do you any good. Samsung phones don't allow installation like that. Only over the air.

I didn't realize that included everything I need, I was expecting something more like J2SM. It doesn't seem to include any documentation though, about the J2ME only functions.

> I seem to recall that many Samsungs don't do cable-based provisioning; you may need to do OTA (over-the-air) provisioning.

That would explain why I couldn’t find the cable anywhere. Are there any guides to doing OTA? I'm guessing it is more complicated than just uploading it to a website and accessing it from your phone, right?

> but personally I use the free version of JCreator.

When I looked into that software I didn't see that there was a freeware version. I will definitely try it.

Thanks for the help everyone!

You're not far off. The only part you missed is where you set the MIME types for jad and jar in the web-server. Click for more in depth explanation.

As i recently have jumped into j2ME myself, i can tell you what i did.
(caution I develope on a mac)


Well First I read this nice little article sitting on GameDev.net:
An Introduction to Developing for Mobile Devices Using J2ME/MIDP (Part 1)

This gave me the basic idea of how things are going to work out, and so i set it up on my PC.

*This is as far as i made it on the Windows Platform*

So the next steps i would take is installing Eclipse then run a google search on J2ME integration with Eclipse lots of stuff comes up.

Now for the mac user...

Went on over to the URL http://www.mpowerplayer.com/developer/ and grabed me up the mpowerplayer SDK.

I then installed such software.

I then browsed on over to the Developer Forums on mpowerplayers website.
S very nice gentleman posted an xCode template to get things up and running, Xcode Template


The only thing i haven't tryed was downloading to my phone... Nothing worth trying out on the phone yet.

Good Luck

      New indie game development studio Knife Entertainment expects to release their debut project My Little Story: Reborn.

      Reborn is the first-person horror containing the spirit of the occultism and mystery. We decided to give players something, which they miss so much in games of this genre: you don't have to hide in dark corners trying to escape from some invulnerable monster. It will be vice versa. We gave players everything to make even the most savage and malicious enemy tremble with fear. You'll face the cruel world full of danger, to expose dark secrets and to fight with ancient evil.

      Our principal credo is our great attention to various details. That's why there are a lot of easter eggs in the form of references and visual quoting of such cult films, games and art works, as The Evil Dead, True Detective, Silent Hill, etc. The release is scheduled for the end of this year.

      Have you ever dreamed of fighting with dinosaurs? If so, then this game is for you. Hold out against the bloodthirsty prehistoric lizards for as long as possible. Seize more weapons, including a shot gun, sword and other stuff. Good luck!

      This is the perfect opportunity to get into the game development industry. Being an Indie team we do not have the creative restrictions often imposed by publishers or other third parties. We are extremely conscientious of our work and continuously uphold a high level of quality throughout our project.
      We are unable to offer wages or per-item payments at this time. However revenue-sharing from crowd-funding is offered to team members who contribute 15-20 hours per week to company projects, as well as maintain constant communication and adhere to deadlines. Currently the crowd-funding campaign is scheduled for the year 2018. Your understanding is dearly appreciated.
       
      Thank you for your time! We look forward to hearing from you!

      Hey everyone
      I've hit a milestone for a side-project of mine I've been working on for some time. It's been a frustrating labor of love, but reached my version 1.0 mark recently
      The asset can be used to create procedural music configurations that are editable in real time in a game. You're able to edit dozens of variables like the scale, mode, tempo, instruments, effects and dozens of other settings to react and adapt to gameplay or other events (or just use it as an easy tool to custom make music for your game). 
      It's available on the unity asset store here: https://www.assetstore.unity3d.com/#!/content/99791
      A demo is available on my github page: https://stickandbindlegames.github.io
      Video Link-Main: https://youtu.be/kDLc6GFdZTk

      Video Link-Features Overview: https://youtu.be/TGQM11iRRUQ
      Video Link-Chiptune example: https://youtu.be/P3BNIbOhSfU
      It's still in active development, despite this release, so I'd be very interested in any feedback ( good or bad), advice, or suggestions for what may make it more appealing to you as developers. It'd be useful to know what features would make it more useful to you as a developer, or feedback on any aspect of the player, really, as I have a few directions I can take the generator for future updates.
      Thanks for your time! I look forward to anyone's thoughts :).
