This application can display map-tiles. Colour map-tiles with 128x128 pixel for multiple resolutions (a multi-resolution pyramid) are used to allow fast zooming. This example displays Munich public transportation. If you figure out the naming convention for the files, you will actually be able to create a JAR archive with your own map. You can send me an image (or a pyramid of images) and I`ll create a JAR/JAD for your mobile, if there are no copyright issues. I`ll then publish the software on the internet. If you need the JAD file, please download it from our website (see link below) because the JAD file created by getjar.com is broken (reference to class file "wedesoft.mobinav.MobiNav" is cropped to "wedesoft.mob")! If you don`t mind bigger Java applications you can download a political world map as well as a New York subway map at the MMVLWiki. You can also get the source-code for this software there under the terms and conditions of the GPL.
