Project Description

Dear bidders,

We are looking for help to improve the performance of Java application (J2ME CLDC) accessing files system.

What we have:


We're implementing an off-line mobile GPS navigation system based on an existed system called GPSMID ([url removed, login to view]). Our version is customized to work with off-line and large local zipped file on the mobile handset. The local file could extend to hundreds of MB to cover the whole country data.

What we need from the bidder:


Improving the speed of loading the vector data of the map from file system and showing the map on the handset screen so that the map could be seen immediately at a given coordinate or after zooming or panning the map. This should work fast like typical navigation applications do (i.e. without jamming and breaking up) in phones like Nokia E50.

We can accept two approaches:

1) improving the way of working with big file


2) configure application to work with higher number of smaller files (in this approach bidder must also propose and implement solution enabling configuring phone in such a way that it will not ask user every time when one of those smaller files is accessed. As well during development when new versions are released often as well for final version they should be runnable without asking user every time)

Please bid on this project ONLY if you have experience and can show previous similar projects in your portfolio. Please include your high level solution to this project and information about SIMILIAR AND RELEVANT projects you made providing demo of them.
