I'm curious as to what methods for reducing jar size exist.

What I have tried so far:
- used pngout
- moved static classes into one single class

I saw on an older thread on this forum that someone suggested Image Optimizer from xat.com. I'll try that.

I still need some more methods.
Thanks.

- obfuscate your code with proguard, with the -overloadaggressively option
- you can combine your png resources into one big resource (the drawback of this method is the heap size)
- you can combine any resource into one resource, but you must be able to read the right resource at the right position
- if your application uses http, you may download resources instead...
- if you initialized static (or not) arrays in your classes, you can use resources to initialize arrays instead. You may gain some bytes...
- move your variable declarations, seems like you can gain some bytes, if the ones most used are placed first (but I've never tried it...)
- avoid interfaces or extension...
- avoid object conception, put everything in one class ;)
- you can try to unjar your jar application, and use "7-zip" (7-zip.org) to re-compress it, and change the midlet size in the jad.
