Uploading .jar midlets larger than 2MB?

« on: August 25, 2008, 02:18:04 PM »

I'm working on an application. The .jar file is now ~2.5MB. Now that it's this big, rumkin and all its clones cease to work; I simply can't find a way to upload this file to my phone.

Does anyone know a way to upload a 2.5MB jar online? I can hardly compress the .jar any more...

Use better compression on the enclosed media files? Whatcha using, 8MP raw jpgs? Wink

Can you post the file in another location and send the URL to yourself via a text message? When you get the text message with the link, you will be able to click on the link and download the file.

Egidio, I've tried uploading the .jar file and then texting myself the link, but I get this in the browser:

"The Requested Page can not be displayed".

mykoleary, my jar contains 3,007 1-bit PNG files, each one being a 220 x 251px Kanji character. They're 1-bit, like I said, so.. we're talkign ~800bytes each. Maybe they're not compressed..? I'll look into it. I thought 1-bit PNG's by default had RLE compression applied. Not sure.

mewantbfp, I'm in Vancouver, hence I don't have a Sprint phone. That link you seems to want a phone number; I'll need to be using my SMS address.

I tried it with my non-sprint phone number just in case, and I get a connection error message anyway; seems like the upload size is the issue, regardless of my Canadian number.

I guess if you open the jar with WinZip etc you should be able to see the actual sizes in there.

If all else fails you could upload the images to your phone's filesystem via USB and then modify the code to read them from there until you figure out how to fix the problem.

This would all be avoided if they actually supported the entire Unicode character set natively. =P

PS - I'm developing an application that is really targeted for a niche audience, most people here won't find it useful. To spill the beans a little, it's for those studying Japanese.

I'm using the 'get resources' method to access the files; no special permission required. It's a much faster/easier way than reading from the file system. The images are all included in the jar as packaged resources. I'm going to double check the compression of the 1-bit PNG's after work. Thanks for the advice..

I'll have to lower the size somehow; if it's this big of a problem for me, then it's surely a hint that mass deployment will be a pain.

Even at 800 bytes each, that's 2.294 megs for just those graphics... Leaving about 210K for code and overhead like comments.

Maybe try making a build script that extracts the comments out before compilation. Also try things like a constant for the path to the resource so you can save characters when referencing it (make it a short name...) Even a shorter directory path might make the zip smaller since it has to reference the path to the graphics.

Comments shouldn't be included in compiled bytecode, anyway. I don't think they're an issue. I'm not exporting the source code/javadocs.

I'm referencing resources, so the directory is '/'; top level. Anyway, 99% of the space is going to the images, so clearly I have to focus on that.

In WinZip, the jar shows a compression of 0% applied to the images. Since I compile using the 'compress jar' option, that means that the PNG's *are*, in fact, compressed, which is why further compression did not succeed.

Does anyone know what other image formats are supported?

you could package your code separate from the images. then have the app download the images the first time it starts up. then write the images to the memory card for future use.

That's true. Again, this is a pain for deployment, though. Am I to make apps that are downloaded by a reasonable number of people, asking them to do the same would be a pain. Sad

Alas, I have cut the width and height of my font 1-bit PNG's exactly in half, and wrote code which scales Image instances. (J2ME scrapped Image scaling/AffineTransformations, so scaling functions have to be implemented manually.)

This leaves my resulting jar at 1.5MB, which I can upload just fine here:

http://pcs.cruz-network.net/

Rumkin doesn't have a 2MB cap, it seems; I get a 'too large' error.

100px images stretched to 200px don't look too great, but it seems to be my best option for now...

Thanks guys for the help!
