Java ME Application Development Discussion

A couple of people, in replies to one of my posts, have shown an interest in writing Java apps for the Eternity. I figured why not start a topic about it so that we can help each other. These are the tools I use:

• JDK 6 Update 12
• NetBeans IDE 6.5 - one of the two packages that supports Java ME
• I also had to modify one of the emulators so that it supports touch screen and is 240x400

If you know anything about Java or programming in general, it is pretty straightforward. Although, there are some things I haven't figured out yet.

One in particular is sound. I can play sound easy enough but it blocks the game thread while it is loading to play. It works fine on the emulator but not the phone. I have tried running it in a different thread.

Awesome thread! too bad I don't know anything about java.

EDIT: ACTUALLY... I will be more than happy to help with graphics/audio engineering. If you need help with anything like that, just ask me.

EDIT2: I'd also like to learn Java. Any good tutorials?

Awesome! I'll work on it tomorrow. You'll have to tell me how you want the buttons/menu though. Shape, color, etc. I can make it look good

EDIT: I'm actually working on it now :p I've already made the bubbles and I'm working of a mock up of a menu. It's gonna be hard though, making a menu for a game about popping bubble wrap 

EDIT2: Sent.

Hey, i found this article the other day when I was searching for any progress on Java accelerometer games... It says its for Sony Ericsson phones but I figured Id post it anyway incase someone might find it useful.

http://developer.sonyericsson.com/site/global/techsupport/tipstrickscode/java/p_jsr256sensorapi_jp8_w910.jsp

Yeah, I took a look in that source and they are using some proprietary Sony-Ericcson libraries that the Samsung certainly wouldn't have.  Does have some interesting stuff on standard J2ME api for looking at sensors so we might be able to get something out of it.

Of course, supposedly Samsung is releasing their Java APIs on http://innovator.samsungmobile.com/ tomorrow so that could give us exactly what we need to write apps that use the accelerometer.

BTW, I wrote up a quick scribble app last night that runs on the Eternity (just to get my feet wet with J2ME).  If you guys are interested I'm happy to post up the source here.  The executable is on Rumkin: Jump Code 3537124

i was wandering if you have looked at the tumbling dice app and see how it works and use it as a guiding point not sure if youre able to but its just a thought

well that sucks i dont know anything about java but maybe there will be something soon...

My theory is that java won't even be able to access the accelerometer.
As you may notice, when you run the Tumbling Dice app,
It doesn't show the Java loading screen, it just goes straight to the app.

With that, I'm not sure if this is a unique type of file that Samsung just made up.
If it is, I'm sure it would be difficult to decode.
If it's a more common type of program, then hopefully, we'll be seein some 3rd party apps
that can access the accelerometer in the near future.
